Technical description

SuperTokens Core is an open source authentication server. From 7.0.0 until 11.0.9, 11.1.4, 11.2.4, 11.3.8, 11.4.8, 12.0.11, 12.1.2, 12.2.1, and 12.3.1, createNewSession can resolve a primary user before unlinkAccounts detaches a login method and then insert the session after unlink has enumerated and revoked the existing sessions. A user who controls the linked login method can exploit this race to retain a signed, database-backed, refreshable session as the former primary identity after that method is unlinked; the session persists until expiry or explicit revocation. This issue is fixed in versions 11.0.9, 11.1.4, 11.2.4, 11.3.8, 11.4.8, 12.0.11, 12.1.2, 12.2.1, and 12.3.1.

———pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev102, pyLoad does not invalidate existing Flask sessions when an administrator changes a user's permissions or password through /api/set_user_permission or /api/change_password. Api.set_user_permission and Api.change_password update the database, but session authorization continues to use role and permission values copied at login by set_session in webui/app/helpers.py. A user can therefore retain revoked privileges or continue using a session established with an old password for the configured session lifetime. API-key authentication is not affected because that path rereads user data from the database. This issue is fixed in version 0.5.0b3.dev102.14h CVE-2026-1237997.4 HIG

——0SuperTokens Core is an open source authentication server. From 11.0.0 until 11.0.9, 11.1.4, 11.2.4, 11.3.8, 11.4.8, 12.0.11, and 12.1.2, Dashboard.isValidUserSession treats any stored session row as valid without comparing DashboardSessionInfo.expiry to the current time. DashboardQueries.getSessionInfoWithSessionId also selects by app and session identifier without an expiry predicate, leaving the periodic DeleteExpiredDashboardSessions cleanup as the only expiration enforcement. An attacker who obtains a dashboard administrator session after its 30-day lifetime can continue using POST /recipe/dashboard/session/verify until the row is removed, and frequent Core restarts can prevent the 12-hour cleanup sweep from running. The stale session retains full dashboard read and write access, but the flaw does not provide a way to guess or acquire the random session identifier. This issue is fixed in versions 11.0.9, 11.1.4, 11.2.4, 11.3.8, 11.4.8, 12.0.11, and 12.1.2.13h CVE-2026-1246225.3 MED

——0A vulnerability was identified in olivier-ls PHP-FTS up to 1.1.3. This impacts the function TrigramIndex::open of the file Storage.php. Such manipulation leads to time-of-check time-of-use. The attack needs to be performed locally. Upgrading to version 1.1.4 will fix this issue. The name of the patch is 0b2fae333d6b022da7ed4c43e2d41aa03f91dff3. Upgrading the affected component is recommended. The project maintainer explains: "[T]he attack requires write access to the index directory by a user other than the one running the application. That is a real shared-hosting scenario and worth defending against, which is why it is fixed but it is a hardening measure rather than a remotely reachable vulnerability, and the "Code Execution" impact additionally assumes the symlink target is a web-served .php file."23h CVE-2026-1064667.5 HIG

——0The JWT Auth WordPress plugin through 3.0.2 does not invalidate previously issued refresh tokens when a user changes or resets their password or removes a connected device, allowing an attacker who obtained a refresh token before such an event to keep issuing valid access tokens and retain authenticated access to the account, up to Administrator.22h CVE-2026-113508—

——0Apache Airflow's logout endpoint attempted to revoke the presented token on the server, but any failure during revocation was silently ignored and logout still reported success. When the auth manager redirects logout to an external logout URL (for example the FAB or Keycloak auth managers), server-side revocation is the only thing that invalidates the Airflow token; it failed on database errors and, reliably, for tokens from an external issuer accepted via `[api_auth] trusted_jwks_url` whose token identifier is longer than 32 characters. Anyone holding a copy of a user's token from before logout could keep using it against the Airflow API until it expired. Users are advised to upgrade to apache-airflow 3.4.0 or later.1d CVE-2026-1231283.7 LOW
