CVE-2026-14916 Kong API Gateway Enterprise: JWT Algorithm-Confusion
A JWT signature verification vulnerability affects Kong components that perform JWT validation for MCP OAuth2 or DataKit integrations inside Kong API Gateway Enterprise. The affected code does not properly validate that the JWT signing algorithm is compatible with the type of key used for...
CVE-2026-85394
python-jose through version 3.5.0 contains an algorithm confusion vulnerability in its HMAC key validation logic. The library fails to properly reject DER-encoded public keys that lack PEM armor or SSH prefixes, allowing them to be accepted as HMAC secrets. An attacker who possesses the service's...
CVE-2026-85394 python-jose through 3.5.0 Algorithm Confusion via DER-encoded Public Key as HMAC Secret
python-jose through 3.5.0 fails to properly validate asymmetric keys in HMAC initialization, accepting DER-encoded public keys that lack PEM armor or SSH prefixes. Attackers holding the service's public key can forge HS256 tokens that pass verification when algorithms are not explicitly restricte...

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
Lemur manages TLS certificate creation. Prior to 1.9.2, the JWT verifier in lemur/auth/service.py:130-137 used fetchtokenheader to read headerdata"alg" from an unverified token and passed that attacker-controlled value to decodewithmultiplesecrets. PyJWT 2.x rejects alg=none with the configured...

Lemur manages TLS certificate creation. Prior to 1.9.2, the JWT verifier in lemur/auth/service.py:130-137 used fetchtokenheader to read headerdata"alg" from an unverified token and passed that attacker-controlled value to decodewithmultiplesecrets. PyJWT 2.x rejects alg=none with the configured...
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...
