CWE-524 10/10/2026
SpeedyCache <= 1.4.2 - Unauthenticated Sensitive Information Exposure via Insecure Cache Configuration via Cache Write Gate Missing comment_author_* Cookie Check
The SpeedyCache – Cache, Optimization, Performance plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.4.2 via the 'comment_author_*, comment_author_email_*' parameter. This makes it possible for unauthenticated attackers to extract the full name and email address of returning commenters pre-filled into comment form input fields and persisted as the site-wide cached page by any unauthenticated attacker requesting the same public URL. The read-side handler in advanced-cache.php correctly skips cached delivery for requests carrying comment_author_* cookies, but this check is absent on the write path, meaning the cache poisoning is invisible to the victim commenter yet fully exploitable by any unauthenticated attacker with no cookies.

Contao: Improper access control in the table access voter
Contao is an Open Source CMS. From version 5.7.0 until 5.7.12, TableAccessVoter::hasAccessToModule() in core-bundle/src/Security/Voter/DataContainer/TableAccessVoter.php caches authorization decisions using only $tokenHash, a hash of the user's security token, and omits the table returned by getDataSource(). If one request first checks a table allowed to the user and then a different denied table, the voter can reuse the allowed result, while DefaultDataContainerVoter can convert an incorrect abstention into a grant. A low-privileged backend user can consequently read, create, update, or delete records in tables outside assigned module permissions, including tables containing member or newsletter-subscriber data. This issue is fixed in version 5.7.12.

Next.js: Pending `use cache` fill can leak Draft Mode content into regular responses and persisted pages
Next.js is a React framework for building full-stack web applications. From 16.3.0 until 16.3.8, pending use cache fills for the same key are shared without separating Draft Mode requests from regular requests. An overlapping regular request can receive unauthenticated unpublished content from an editor's Draft Mode fill, while an overlapping Draft Mode request can receive published content from a regular fill. When the regular request prerenders a page, the draft-dependent content can persist in the generated page and be served to later visitors until revalidation. Sites are affected when Cache Components or experimental.useCache is enabled and cached functions return draft-dependent content. This issue is fixed in version 16.3.8.

Next.js: Cache poisoning of SSG and ISR pages in self-hosted Next.js applications
Next.js is a React framework for building full-stack web applications. From 15.0.0 until 15.5.27 and 16.3.8, self-hosted applications using the Pages Router with statically generated or Incremental Static Regeneration pages can key a response cache entry without sufficiently binding it to the source route. A request can replace one page's cache entry with content from a different route, causing the affected page to serve incorrect content to every visitor until revalidation. Applications deployed on Vercel are not affected. This issue is fixed in versions 15.5.27 and 16.3.8.

Next.js: Cache poisoning in Next.js SSG/ISR rendering leads to cross-user content substitution and persistent denial of service
Next.js is a React framework for building full-stack web applications. From 15.0.0 until 15.5.27 and 16.3.8, applications with a root-level catch-all page and statically generated or Incremental Static Regeneration routes can use a shared response cache key that is insufficiently scoped to the source route. A single unauthenticated crafted request can poison that cache, causing cross-user content substitution or persistent denial of service until the poisoned entry is revalidated or replaced. This issue is fixed in versions 15.5.27 and 16.3.8.

CWE-524 01/10/2026
next.js cache leak on warm `use cache` handlers accessing root param
Next.js versions from 16.3.0 to 16.3.7 warm `use cache` handlers using `next/root-params` and can leak their return value to pages with different root params. With Cache Components enabled (cacheComponents: true), a 'use cache' function that calls another 'use cache' function that reads a root param can be keyed incorrectly when the inner call is served from an existing entry: the enclosing function's cache key then omits that root param. The enclosing entry is written once and reused for all root param values, so a response for one root param value can serve content produced for a different value — whether the page is prerendered at build time or at runtime, or rendered dynamically. Shared cache headers let downstream caches redistribute the content further.
What values are leaked cannot be attacker controlled. Which value's content is served depends only on which invocation wrote the entry first.
This has been patched in 16.3.8.

CWE-524 22/09/2026
Token Cache Reuse in mcp-toolbox-sdk-python
A caching flaw in the toolbox-core package of the mcp-toolbox-sdk-python SDK causes the same Google ID token to be cached and reused across different audiences. If an application uses the SDK to authenticate to two or more different audiences within the same process, the module-level token cache fails to key its cached tokens by the requested audience. Consequently, a valid, unexpired token minted for a sensitive service (Service A) can be retrieved from the cache and sent to a secondary service (Service B). An attacker who operates, compromises, or monitors traffic to Service B can capture this token and replay it to impersonate the victim application against Service A.

http-cache-semantics through 4.2.0 Cross-User Cache Disclosure via max-stale
http-cache-semantics through 4.2.0 fails to properly validate security-zeroed cache entries when processing client max-stale directives, allowing unauthenticated attackers to retrieve cached responses belonging to other users. Attackers can request the same URL with a large max-stale value to obtain another user's Set-Cookie session credentials from shared-cache entries that were deliberately zeroed for security reasons.

mpp writes Payment-Receipt and Cache-Control before the wrapped application runs, letting a consumer's own Cache-Control expose paid responses to shared caches
Use of Cache Containing Sensitive Information in ZenHive mpp allows a shared HTTP cache to store a paid response and serve it to clients that never paid.
MPP.Plug.verify_credential in lib/mpp/plug.ex sets payment-receipt and cache-control: private on the connection before the wrapped application runs, and registers no register_before_send/2 callback. Plug.Conn.put_resp_header/3 replaces an existing header, so a mounting application that sets its own cache-control on the paid resource (for example public, max-age=3600) silently overrides the private the library relies on, and a CDN or reverse proxy can then store the paid 200 together with its Payment-Receipt and serve both to unpaid clients. The library-level guarantee is therefore defeatable by the application it protects. For the same reason a downstream non-2xx response still carried Payment-Receipt, issuing a receipt for a response that delivered no resource.
This issue affects mpp: from 0.1.0 before 0.16.2.

ash_authentication_oauth2_server serves tenant-specific OAuth metadata as publicly cacheable without Vary, enabling cross-tenant confusion
Use of Cache Containing Sensitive Information vulnerability in ash-project ash_authentication_oauth2_server allows a shared HTTP cache to serve one tenant's OAuth discovery metadata to another tenant's clients.
The RFC 8414 and RFC 9728 metadata endpoints in AshAuthentication.Phoenix.Oauth2Server.ProtocolRouter return tenant-specific values (issuer, authorization_endpoint, token_endpoint, jwks_uri) when a tenant is set, but sent them with Cache-Control: public, max-age=3600 and no Vary. When the tenant is derived from something other than the URL (a header or the Host) and a shared cache sits in front, the cache key is the URL alone, so a stored response for one tenant is served to another for up to an hour. Affected clients may then send authorization codes and secrets to the wrong tenant's token endpoint and validate tokens against the wrong keys.
This issue affects ash_authentication_oauth2_server: from 0.1.3 before 0.3.1.

Catalyst::Plugin::Static::Simple versions through 0.38 for Perl mark responses as publicly cacheable
Catalyst::Plugin::Static::Simple versions through 0.38 for Perl mark responses as publicly cacheable.
The _serve_static method always sets the Cache-Control header to "public", with no means of overriding it. This advises proxies that the content may be stored in a shared cache, and may be reused in responses to requests from other users. (This includes requests with an Authorization header.)
Configuring the expires time to "0" to disable caching, as documented, is ignored.

Netty: Cache Poisoning and Information Disclosure via CORS Vary Header Overwrite
Netty is an asynchronous, event-driven network application framework. Prior to 4.1.137.Final and 4.2.17.Final, io.netty.handler.codec.http.cors.CorsHandler setVaryHeader replaces application Vary headers such as Authorization or Cookie with Origin, allowing a caching proxy or CDN to reuse authenticated responses across users and disclose sensitive information.

Nuxt is an open-source web development framework for Vue.js. From 4.4.0 until 4.5.1, runtime cache:nuxt:payload entries for /<page>/_payload.json can be returned before route middleware and page guards because import.meta.prerender is not enforced, disclosing another user's SSR data. This issue is fixed in 4.5.1.

Next.js: Response Body Cache Confusion for Requests Containing Bodies
Next.js is a React framework for building full-stack web applications. In versions 12.0.0 through 15.5.20 and 16.0.0 through 16.2.10, a server-side fetch with a request body may return a cached response body from a different request to the same URL but different body. Confidential data in the POST's response body would then leak to unauthorized requests. Though the request itself will not be deduped. This only applies to fetch calls with a request that has a different init than the one passed to fetch. A safe request would be: fetch(new Request(init), init). An unsafe request would be: fetch(new Request(init), aDifferentInit). This issue has been fixed in versions 15.5.21 and 16.2.11.

Directus: Authorization-dependent response served from unsegmented cache key
Directus is a real-time API and App dashboard for managing SQL database content. Prior to 12.0.0, when response caching is enabled, the cache-key derivation in api/src/utils/get-cache-key.ts includes version, path, query, and accountability.user but omits authorization context such as share, role, roles, admin, app, and policies. Directus share tokens and anonymous requests can both reduce to user null, so different shares or anonymous clients requesting the same URL and query can receive a permission-filtered cached response without permission re-evaluation. This issue is fixed in version 12.0.0.

Potential exposure of private data via cached Set-Cookie response
An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16.
`UpdateCacheMiddleware` and the `cache_page()` decorator cache responses that vary on cookies when the incoming request carries unrelated cookies, which allows remote attackers to read private data from the shared cache.
Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.
Django would like to thank Chris Whyland for reporting this issue.

API Platform Core: Cross-user attribute leak in JSON:API and HAL item normalizers due to missing isCacheKeySafe gate
API Platform Core is a system to create hypermedia-driven REST and GraphQL APIs. In versions from 2.6.0 prior to 4.1.29, 4.2.26, and 4.3.12, a missing isCacheKeySafe gate in the JSON:API and HAL item normalizers causes a cross-user attribute leak. #[ApiProperty(security: ...)] is evaluated per request to decide whether a property is exposed. The componentsCache arrays in ApiPlatform\JsonApi\Serializer\ItemNormalizer and ApiPlatform\Hal\Serializer\ItemNormalizer are keyed on $context['cache_key'], which is set unconditionally before delegating to the parent normalizer. The component structure (attributes, relationships, links) computed for one request can therefore be reused for a subsequent request whose user has a different set of accessible properties. A user with lower privileges may end up seeing the structure of properties that the security predicate would otherwise have hidden for them. This issue has been fixed in versions 4.1.29, 4.2.26, and 4.3.12.

Ghost CMS: envenenamento de cache via cabeçalho x-ghost-preview (CVE-2026-53943)
Ghost é um sistema de gerenciamento de conteúdo baseado em Node.js. Desde até 6.37.0, quando o Ghost está atrás de uma camada de cache compartilhada que faz com que o conteúdo em cache seja compartilhado entre visitantes diferentes, um usuário não autenticado poderia enviar um cabeçalho x-ghost-preview que alterava a resposta renderizada do frontend. Em configurações de cache afetadas, essa resposta poderia ser armazenada e servida a visitantes subsequentes que solicitassem a mesma página, permitindo o envenenamento de cache da saída de pré-visualização específica da requisição. Quando o frontend e o painel administrativo do Ghost são executados no mesmo domínio, isso poderia ser usado para assumir contas de usuários da equipe. Quando são executados em domínios diferentes, as contas da equipe não ficam expostas. Esta vulnerabilidade está corrigida na versão 6.37.0.

Angular: Information Leak via Default Caching of Credentialed Requests in HttpTransferCache
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23, a vulnerability was discovered in @angular/common when Server-Side Rendering (SSR) and hydration are enabled. The HttpTransferCache utility optimizes hydration by caching outgoing HTTP requests performed during SSR and transferring the cached state to the client-side application via TransferState. However, the caching mechanism fails to inspect the withCredentials flag or the Cookie header of outgoing requests. As a result, credentialed, user-specific responses may be cached by default in the shared TransferState payload. When these responses are serialized into the HTML, any caching layer (such as a CDN, reverse proxy, or shared server cache) that caches the SSR-rendered HTML page could inadvertently cache and leak one user's private data to other users, leading to a high-severity information disclosure vulnerability. This vulnerability is fixed in 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23.

CWE-524 17/06/2026
undici vulnerable to cross-user information disclosure via shared cache whitespace bypass
Impact:
Undici's cache interceptor incorrectly classifies some responses as cacheable when the upstream Cache-Control header uses whitespace-padded qualified private or no-cache field names such as private=" authorization" or no-cache="\tauthorization". The parser preserves the surrounding whitespace, so later comparisons against the literal authorization field name fail and the response is stored.
In shared-cache mode, this allows a response containing one user's authenticated data to be served from cache to a subsequent caller, including an unauthenticated caller, when both requests resolve to the same cache key.
Affected applications are those that explicitly enable the cache interceptor (interceptors.cache()) in shared mode, forward Authorization headers upstream, and receive cacheable responses with non-canonical qualified private or no-cache directives.
Patches:
Upgrade to undici v7.28.0 or v8.5.0.
Workarounds:
If upgrade is not immediately possible, disable shared-cache mode for traffic that includes Authorization headers, avoid caching responses to authenticated requests, or add Vary: Authorization upstream.
