Blacklist Manager for WooCommerce 1.3.0 - 2.3.1 - Blocked User Restriction Bypass via XML-RPC and Application Passwords
The Blacklist Manager for WooCommerce WordPress plugin from 1.3.0 to 2.3.1 does not enforce its user blocking on every authentication path, allowing the holder of an account the site owner has blocked to keep authenticating with that account's privileges, without the block being enforced or recorded.

Snipe-IT: 2FA bypass via the API token flow
Snipe-IT is an IT asset/license management system. Prior to 8.7.0, a password-authenticated session for an account with self.api permission can reach the personal-access-token API flow before completing the account's second-factor challenge because CheckForTwoFactor is enforced in the web middleware group but not the API middleware group. The advisory states that the resulting persistent API token can read and modify resources with the victim's permissions and, for an administrator, can reach the users/two_factor_reset endpoint. Resetting the administrator's enrolled second factor allows the password-holding attacker to enroll an attacker-controlled factor, take over the administrator's web account, and lock out the legitimate user. The token does not create a web session, but it provides broad API access while the same browser session remains blocked at the two-factor page. This vulnerability is fixed in 8.7.0.

CWE-288 Sep 21, 2026
Sync-in Server has a complete 2FA Bypass via `POST /api/auth/token`
Sync-in Server is an open-source platform for file storage, sharing, collaboration, and syncing. Prior to version 2.4.0, `POST /api/auth/token` authenticates with username and password only, then calls `getTokens()`, which returns full access and refresh JWTs without checking whether the account has TOTP 2FA enabled. An attacker with stolen or phished credentials can bypass 2FA in a single request. The parallel login endpoint (`POST /api/auth/login`) correctly enforces 2FA by calling `setCookies(user, res, true)`, which gates on `user.twoFaEnabled`. Version 2.4.0 patches the issue.

Steeltoe: Header-forwarded client cert lacks proof of private-key possession
Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. Prior to 4.3.0, Steeltoe.Security.Authorization.Certificate deployments using AddOrgAndSpacePolicies() and UseCertificateAuthorization() trust the public certificate supplied in the X-Client-Cert request header without proving possession of the corresponding private key. Common Cloud Foundry routers do not remove this header from inbound requests. When inbound requests are not restricted to a known trusted proxy source IP, an attacker who obtains the public certificate of an application instance in the target organization or space and can reach the application can spoof X-Client-Cert to bypass the SameOrg and SameSpace policies for the certificate validity period. This issue is fixed in version 4.3.0.

Kong API Gateway Enterprise: SAML Authentication bypass
A SAML authentication bypass vulnerability affects the Kong SAML plugin when the validate_assertion_signature option is explicitly set to false. This option is enabled by default. When disabled, the plugin may extract the SAML identity from an unsigned assertion and authenticate the user without verifying a valid cryptographic signature.
As a result, an unauthenticated remote attacker may be able to submit a crafted SAML response and impersonate arbitrary users, including administrators

[UNREVIEWED] OAuth Callback Login Bypasses Deactivated-Account Checks
Concrete CMS OAuth callback login path prior to version 9.5.3 did not check whether an account was active or email-validated before establishing a session. A deactivated or unvalidated user with an existing OAuth binding could complete authentication and receive a session that was fully authenticated for the callback response, with the login recorded and login events dispatched. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 6.3 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N.

Capgo AAL1 Session MFA Bypass via Direct RBAC Authorization
Capgo (Cap-go/capgo.app) contains an authentication bypass affecting all versions (no patched version available at time of publication). The Edge authorization path allows a password-only Supabase aal1 session to exercise privileged RBAC permissions even when the account has a verified MFA factor that has not been used for the session: the Edge JWT middleware (foundJWT() in supabase/functions/_backend/utils/hono_middleware.ts) accepts the JWT without validating its assurance level, and the direct RBAC path (checkPermission()/checkPermissionPg() in supabase/functions/_backend/utils/rbac.ts calling public.rbac_check_permission_direct()) authorizes by user ID without passing or checking the session aal, unlike the public.verify_mfa() control which correctly requires aal2. An attacker who knows only the victim's password can therefore authenticate, mint a persistent app-scoped app_admin API key that remains valid after the aal1 session is logged out, and perform privileged operations such as modifying production OTA channel configurations (validated by changing a public production channel from bundle 1.0.0 to 1.0.1), defeating the protection provided by MFA.

n8n: Disabled OIDC SSO Endpoints Remain Active and Issue Valid Sessions
n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the public OIDC login and callback endpoints completed authentication even when OIDC was not the enabled active authentication method. An Enterprise administrator who had configured and later disabled an identity provider still exposed a working route that could issue valid sessions. The affected logic is packages/cli/src/modules/sso-oidc/oidc.service.ee.ts, including generateLoginUrl and the callback flow that lacked assertOidcLoginEnabled. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.

Authentication Bypass Using an Alternate Path or Channel in Siemens Reyrolle 7SR5
A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). Server-side authorization checks in the web-based management interface are not properly enforced, allowing role-based access control (RBAC) restrictions to be bypassed through manipulation of request data. This could allow an authenticated, low-privileged remote attacker to escalate privileges to an administrative level.

fastify vulnerable to authentication bypass via malformed URLs reaching encapsulated not-found handlers
fastify versions >= 4.0.0 and before 5.12.2 can route a malformed URL sent under one plugin prefix to the custom not-found handler of a different sibling plugin, and invoke it without the preHandler hook declared for that handler. The internal not-found router for encapsulated handlers dispatches malformed paths through a single shared handler pointer before URL decoding, ignoring the prefix and skipping the selected handler's normal lifecycle. An unauthenticated attacker can therefore reach an authentication-protected private fallback through an unrelated public prefix and read its full response, bypassing the authentication hook and breaking prefix encapsulation. Users should upgrade to fastify 5.12.2 or later.
