CVE-2026-82454

CVE-2026-82454 is a CRITICAL authentication bypass in the Omnivore API (packages/api), affecting versions before android-0.227.0 . The decodeAppleToken function extracted the alg field from an attacker-supplied JWT header and passed it as the sole allowed algorithm to jwt.verify(). Because jsonwe...

CVE-2026-82454 Omnivore before android-0.227.0 Authentication Bypass via Apple Sign-in

The Omnivore API packages/api before the fix in commit abf53d6 contains an authentication bypass in Apple sign-in token verification. The decodeAppleToken function extracted the 'alg' field from the attacker-supplied JWT header and passed it as the sole allowed algorithm to jwt.verify. Using...

BIT-KEYCLOAK-2026-11800 Org.keycloak:keycloak-services: keycloak: authentication bypass via jwt algorithm confusion

A flaw was found in Keycloak. This JWT algorithm confusion vulnerability in the JWT Authorization Grant flow allows an attacker with valid client credentials to bypass signature verification. By forging an assertion, the attacker can create unauthorized access tokens. This enables the attacker to...

CVE-2026-55165

In Lemur 1.9.0 and earlier, lemur/auth/service.py:130-137 reads the alg field from an unverified JWT header and passes it to pyjwt.decode(..., algorithms=[header_data["alg"]]), letting an attacker choose the verification algorithm. PyJWT 2.x blocks alg=none, so direct ATO requires a separate LEMU...
