Title
phpMyFAQ before 4.1.7 2FA Bypass via Remember-Me Cookie
Summary
phpMyFAQ before 4.1.7 contains a two-factor authentication bypass vulnerability where remember-me tokens are issued before 2FA verification completes. Attackers with valid credentials can obtain a remember-me cookie, skip the 2FA challenge, and replay the cookie to gain full authenticated access without second-factor verification.

Title
Serendipity < 2.6.1 Authentication Bypass via Username Collision
Summary
Serendipity before 2.6.1 contains an authentication context confusion vulnerability where password validation and session loading operate independently without ensuring both use the same user record. An authenticated Editor can create a username collision with an Administrator account and obtain administrative privileges by logging in with their own password while the session loads the Administrator's account data.

Title
Apache CXF: OAuth2 Dynamic Client Registration Scope Self-Escalation
Summary
In Apache CXF's OAuth2 Dynamic Client Registration endpoint, the authorization server accepts and stores the `scope` value supplied in the client registration request verbatim, without validating it against an AS-defined allowlist. This could lead to a client self-assigning privileged scopes at registration time. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.

Title
TOTP enrollment hijack: password gate skipped due to unawaited promise
Summary
Pingvin Share X is a secure and easy self-hosted file sharing platform. A vulnerability in versions 1.5.0 through 1.18.0 allow an attacker to bypass password verification when managing Time-based One-Time Password (TOTP) settings. The root cause is a missing `await` keyword on calls to the asynchronous `verifyPassword` method in `authTotp.service.ts` and the `authenticateUser` method in `auth.service.ts`. In JavaScript, an unawaited `Promise` is always truthy. So the logic intended to throw a `ForbiddenException` when a password is incorrect. It never executes because the expression evaluates the existence of the `Promise` object rather than its resolved boolean result. The vulnerability is fixed in version 1.18.1 by ensuring all asynchronous authentication calls are properly awaited. There are no official workarounds. If a user is locked out, an administrator must manually reset the user's TOTP status in the database.

"value": "Pingvin Share X is a secure and easy self-hosted file sharing platform. A vulnerability in versions 1.5.0 through 1.18.0 allow an attacker to bypass password verification when managing Time-based One-Time Password (TOTP) settings. The root cause is a missing `await` keyword on calls to the asynchronous `verifyPassword` method in `authTotp.service.ts` and the `authenticateUser` method in `auth.service.ts`. In JavaScript, an unawaited `Promise` is always truthy. So the logic intended to throw a `ForbiddenException` when a password is incorrect. It never executes because the expression evaluates the existence of the `Promise` object rather than its resolved boolean result. The vulnerability is fixed in version 1.18.1 by ensuring all asynchronous authentication calls are properly awaited. There are no official workarounds. If a user is locked out, an administrator must manually reset the user\u0027s TOTP status in the database."

ChurchCRM: Incomplete fix for CVE-2026-40582: public API login still bypasses 2FA and account lockout in ChurchCRM 7.2.2
Summary
ChurchCRM is an open-source church management system. From 7.2.0 to 7.2.2, The fix for CVE-2026-4058 is incomplete. The hardening commit was merged and then silently stripped from src/api/routes/public/public-user.php by an unrelated PR before any 7.2.x tag was cut. Every shipped 7.2.x release therefore remains exploitable by the PoC published with the original advisory. This vulnerability is fixed in 7.3.1.

Title
Termix: Pending-TOTP temporary token can regenerate backup codes and neutralize TOTP
Summary
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.1.0, /users/login issues a temporary JWT (temp_token) for TOTP-enabled accounts. That token carries a pendingTOTP state and should only be valid for the second-factor flow. However, the auth middleware accepts this token on regular authenticated endpoints. This effectively turns 2FA into single-factor (password) for impacted accounts. This issue has been patched in version 2.1.0.
