CVE-2026-103869 Média · 6.5 CWE-488 07/10/2026
Pulp-ansible: bearer tokens are reused across remotes in a worker
A flaw was found in pulp-ansible's bearer-token refresh for collection remotes. The access token is kept in one module-level variable and reused for every token download in that worker. A user who can sync an Ansible remote that uses token refresh, and can point that remote at a server they control, receives an access token obtained for a different remote, and can reuse it at the service that issued it. Content stored in Pulp is not changed, and the service is not stopped.
CVE-2026-103868 Média · 6.5 CWE-488 07/10/2026
Pulp-container: registry credentials are reused across remotes in a worker
A flaw was found in pulp-container when it authenticates to an upstream registry. Basic and bearer credentials from one remote are reused for later downloads in the same worker. A user who can sync a container remote, and can point that remote at a server they control, receives the username, password, or bearer token stored for a different remote, and can reuse that credential at the upstream registry. Content stored in Pulp is not changed, and the service is not stopped.
CVE-2026-82806 Média · 5.3 CWE-488 01/10/2026
Apache APISIX: cross-request permission pollution via static permission list mutation
Exposure of data element to wrong session vulnerability in Apache APISIX. This issue affects Apache APISIX: from 2.3.0 before 3.7.0. Under a supported authz-keycloak configuration, a request's authorization scope could persist into later requests on the same route, leading to unintended authorization expansion and inconsistent access-control decisions. Users are recommended to upgrade to version 3.7.0 or higher, which fixes the issue.
CVE-2026-103544 Média · 6.3 CWE-488 01/10/2026

A vulnerability was found in datadrivenconstruction OpenConstructionERP up to 14.8.1. The impacted element is an unknown function of the file backend/app/modules/ai/ai_client.py of the component Al Provider Configuration Handler. Performing a manipulation results in exposure of data element to wrong session. The attack may be initiated remotely. The exploit has been made public and could be used. Upgrading to version 15.0.0 is sufficient to resolve this issue. It is suggested to upgrade the affected component.
CVE-2026-88017 Alta · 7.3 CWE-488 10/09/2026
rclone: FTP cross-session auth-proxy backend confusion
rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.64.0 until 1.75.1, the FTP auth-proxy driver in cmd/serve/ftp/ftp.go stores one obscured password per username in the server-wide userPass map[string]string instead of binding the credential or VFS to the authenticated session. If two accepted credentials use the same username but resolve to different proxy backends, a later CheckPasswd login overwrites userPass[user], and subsequent getVFS operations on the first session are reauthorized with the later password. The first session can then read, create, overwrite, rename, or delete objects using the second credential’s backend authority. Exploitation requires the later same-username login to occur while the first session remains open. This issue is fixed in version 1.75.1.
CVE-2026-84685 Média · 6.5 CWE-488 08/09/2026
Improper Cache Isolation in auth0/react-native-auth0 SDK Web Platform Credential Management
The react-native-auth0 SDK's web platform implementation does not scope its in-memory token cache to individual user sessions when operating in a server-side rendering (SSR) environment where module state persists across HTTP requests. Under the listed preconditions, tokens cached in module memory can be retrieved across subsequent requests processed by the same server runtime.

CVE-2026-80231 Alta · 7.5 CWE-488 06/09/2026
native CA store conn reuse
A flaw in libcurl makes it wrongly reuse an existing HTTPS connection setup for a given hostname even when using a different Native CA Store setting (`CURLSSLOPT_NATIVE_CA`) than when the connection was created.
CVE-2026-19931 Crítica · 9.8 CWE-488 06/09/2026
Negotiate ambient user conn reuse
A flaw in libcurl makes it wrongly reuse an HTTP connection setup for a given hostname using Negotiate authentication, when the initial request is done using empty credentials. This can make user B's request get sent over user A's previously authenticated connection.
CVE-2026-18489 Alta · 7.4 CWE-488 04/09/2026
IBM ContextForge Translate is affected by cross-client credential context confusion
IBM ContextForge MCP Gateway - Translate utility <= 1.0.8 MCP Context Forge could allow a remote attacker to obtain sensitive information from other sessions due to exposure of data elements to the wrong session.
CVE-2026-82367 Baixa · 2.3 CWE-488 30/08/2026
Re-entrant synchronous publish in AshGraphql subscription batcher delivers one subscriber's records to another's topic
Exposure of Data Element to Wrong Session vulnerability in ash-project ash_graphql can deliver one subscription's resolved records to a different subscriber's topic. AshGraphql.Subscription.Batcher.do_send/5 reads the resolved batch from the process dictionary via Process.get(:batch_resolved) and then unconditionally deletes it. That is sound only inside a task the library owns. On the :backpressure_sync and :noproc fallbacks do_send/5 runs inline in the publishing caller's process, so if a resolver inside an outer do_send/5 triggers another synchronous Ash notification, the inner call finds the outer run's value still under :batch_resolved, adopts it as its own result, and publishes it to the inner topic, a different subscription document with a different actor and tenant. It then deletes the key, so the outer run publishes nothing. The key is not namespaced by run, so records cannot be told apart. The fix saves, clears, and restores :batch_resolved around each run. This issue affects ash_graphql: from 1.4.0 before 1.11.0.
CVE-2026-71850 Média · 4.8 CWE-488 07/08/2026
Hono: `memo()` retains SSR output across requests, leading to cross-user data disclosure
Hono is a Web application framework that provides support for any JavaScript runtime. From 3.8.0 to 4.12.33, memo() from hono/jsx retains the result of a server side render and reuses it for later renders with comparator equal props, and request scoped values read inside the component take no part in that comparison, so a response can contain HTML rendered for another user's request. Components wrapped with memo() are compared by props alone; values read implicitly during rendering, such as JSX Context through createContext() and useContext(), useRequestContext() from hono/jsx-renderer, and getContext() from hono/context-storage, do not participate, and the retained result lives as long as the wrapped component, so it outlives the request that produced it. A user may receive a response containing HTML rendered for another user when both render the same memoized component with comparator equal props on the same warm instance, which may disclose another user's account or profile data, disclose request scoped secrets embedded in HTML such as CSRF tokens, or expose role specific content to users who should not receive it. This issue is fixed in version 4.12.34.
CVE-2026-16326 Crítica · 10.0 CWE-488 29/07/2026
consul-mcp-server vulnerable to cross-tenant credential reuse in streamable-HTTP stateless mode
In consul-mcp-server, versions 0.1.0 up to 0.1.3 did not properly isolate session state in stateless mode, which may allow one client's Consul authentication token to be used for subsequent requests from other clients. This vulnerability (CVE-2026-16326) is fixed in consul-mcp-server 0.1.4.
CVE-2026-16498 Crítica · 10.0 CWE-488 28/07/2026
terraform-mcp-server vulnerable to cross-tenant credential reuse in streamable-HTTP stateless mode
The terraform-mcp-server before version 1.1.0 is vulnerable to a cross-tenant credential reuse issue in the streamable-HTTP stateless transport mode that may allow one user's Terraform token to be used to execute tool calls on behalf of subsequent users. This vulnerability, CVE-2026-16498, is fixed in terraform-mcp-server 1.1.0.
CVE-2026-14621 Baixa · 3.1 CWE-488 04/07/2026
FederatedAI FATE OSX Broker QueuePushReqStreamObserver.java QueuePushReqStreamObserver.initEggroll wrong session
A vulnerability has been found in FederatedAI FATE up to 2.2.0. This affects the function QueuePushReqStreamObserver.initEggroll of the file java/osx/osx-broker/src/main/java/org/fedai/osx/broker/grpc/QueuePushReqStreamObserver.java of the component OSX Broker. Such manipulation of the argument rollSiteSessionId/dstRole/dstPartyId leads to exposure of data element to wrong session. The attack can be executed remotely. A high complexity level is associated with this attack. It is indicated that the exploitability is difficult. The exploit has been disclosed to the public and may be used. The pull request to fix this issue awaits acceptance.
CVE-2026-8458 Média · 6.5 CWE-488 03/07/2026
wrong reuse for different services
libcurl might in some circumstances reuse the wrong connection when asked to do Negotiate-authenticated ones, even when they are set to use different "services". libcurl features a pool of recent connections so that subsequent requests can reuse an existing connection to avoid overhead. When reusing a connection a range of criteria must be met. Due to a logical error in the code, a request that was issued by an application could wrongfully reuse an existing connection to the same server that was authenticated using different services.
CVE-2026-54311 Alta · 7.7 CWE-488 23/06/2026
n8n: Merge Node SQL Mode Prototype Pollution
n8n is an open source workflow automation platform. Prior to 2.25.7 and 2.26.2, an authenticated user with permission to create or modify workflows could pollute the sandbox used by the Merge node's SQL Query mode. Because the sandbox context was cached and reused across all workflow executions on the instance, prototype mutations introduced by one user's workflow persist into subsequent Merge SQL executions belonging to other users or projects. This allowed a low-privileged attacker to intercept workflow data processed by other users on the same instance. This issue only affects multi-user n8n instances where more than one user has permission to create and execute workflows containing the Merge node in SQL Query mode. This vulnerability is fixed in 2.25.7 and 2.26.2.
CVE-2026-34391 Alta · 7.5 CWE-488 27/03/2026
Fleet Vulnerable to Windows MDM cross-device command disclosure
Fleet is open source device management software. Prior to 4.81.1, a vulnerability in Fleet's Windows MDM command processing allows a malicious enrolled device to access MDM commands intended for other devices, potentially exposing sensitive configuration data such as WiFi credentials, VPN secrets, and certificate payloads across the entire Windows fleet. Version 4.81.1 patches the issue.
CVE-2026-23919 Média · 6.0 CWE-488 24/03/2026
Insufficient isolation of JavaScript (Duktape) execution context on Zabbix Server
For performance reasons Zabbix Server/Proxy reuses JavaScript (Duktape) contexts (used in script items, JavaScript reprocessing, Webhooks). This can lead to confidentiality loss where a regular (non-super) Zabbix administrator leaks data for hosts they do not have access to. A fix has been released that makes the built in Zabbix JavaScript objects read-only, but please be advised that usage of global JavaScript variables is not recommended because their content could be leaked. More information <a href='https://www.zabbix.com/documentation/7.4/en/manual/installation/known_issues#preprocessing-global-variables-are-unsafe'>in Zabbix documentation</a>.
CVE-2026-27492 Média · 4.7 CWE-488 21/02/2026
Lettermint Node.js SDK leaks email properties to unintended recipients when client instance is reused
Lettermint Node.js SDK is the official Node.js SDK for Lettermint. In versions 1.5.0 and below, email properties (such as to, subject, html, text, and attachments) are not reset between sends when a single client instance is reused across multiple .send() calls. This can cause properties from a previous send to leak into a subsequent one, potentially delivering content or recipient addresses to unintended parties. Applications sending emails to different recipients in sequence — such as transactional flows like password resets or notifications — are affected. This issue has been fixed in version 1.5.1.
CVE-2026-23646 Média · 6.5 CWE-488 19/01/2026
OpenProject users can delete other user's session, causing them to be logged out
OpenProject is an open-source, web-based project management software. Users of OpenProject versions prior to 16.6.5 and 17.0.1 have the ability to view and end their active sessions via Account Settings → Sessions. When deleting a session, it was not properly checked if the session belongs to the user. As the ID that is used to identify these session objects use incremental integers, users could iterate requests using `DELETE /my/sessions/:id` and thus unauthenticate other users. Users did not have access to any sensitive information (like browser identifier, IP addresses, etc) of other users that are stored in the session. The problem was patched in OpenProject versions 16.6.5 and 17.0.1. No known workarounds are available as this does not require any permissions or other that can temporarily be disabled.
CVE-2025-24934 Média · 5.4 CWE-488 22/10/2025
SO_REUSEPORT_LB breaks connect(2) for UDP sockets
Software which sets SO_REUSEPORT_LB on a socket and then connects it to a host will not directly observe any problems. However, due to its membership in a load-balancing group, that socket will receive packets originating from any host. This breaks the contract of the connect(2) and implied connect via sendto(2), and may leave the application vulnerable to spoofing attacks. The kernel failed to check the connection state of sockets when adding them to load-balancing groups. Furthermore, when looking up the destination socket for an incoming packet, the kernel will match a socket belonging to a load-balancing group even if it is connected, in violation of the contract that connected sockets are only supposed to receive packets originating from the connected host.
