CVE-2026-66908

CVE-2026-66908 — camel-platform-http-main JWT iss/aud not validated Runnable proof-of-concept reproducer for the Apache Camel vulnerability where the camel-main embedded HTTP server builds its JWT authenticator from a keystore alone when neither jwtIssuer nor jwtAudience is configured, so inbound...

filelock: StrictSoftFileLock follows a symbolic link swapped in at <path>.filelock and creates claim files in a directory another local user chooses

StrictSoftFileLock and AsyncStrictSoftFileLock check .filelock the coordination directory that holds the lock's state with one lstat call on its name. lstat reports what a name is without following a symbolic link a file that redirects to another path. After that check, the code reaches...

CVE-2026-89315

"JwtClaims.MarshalJSON" built a Go struct at runtime with "reflect.StructOf", synthesising a field named ""A" + claimName" for each untyped claim. "reflect.StructOf" panics when a field name is not a valid Go identifier, or when it duplicates another field. Both conditions are reachable from...

CVE-2026-114618

A flaw was found in Authlib. In the default JSON Web Token JWT bearer grant implementation, audience claims are checked only for existence rather than validated against the target authorization server. A remote attacker holding a legitimate token issued for another service can present it to a...

CVE-2026-98669

In the Linux kernel, the following vulnerability has been resolved: iio: buffer: serialize buffer teardown with mode claims Buffer-mode claims hold mlock to guarantee that the device remains in buffer mode until the claim is released. Normal buffer updates take infoexistlock followed by mlock in...

Improper Handling of Exceptional Conditions

Overview Affected versions of this package are vulnerable to Improper Handling of Exceptional Conditions via the token parsing process. An attacker can cause the service to terminate threads and degrade availability by submitting JWTs with timestamp claims containing out-of-range values...

CVE-2026-110112

Dockhand before 1.0.50 contains a privilege escalation vulnerability that allows users from another tenant to gain admin access because OIDC iss, aud, nonce and exp claims are not validated. Attackers with admin rights in another tenant of a shared provider like Microsoft Entra ID can recreate th...

CVE-2026-107724

fast-jwt provides fast JSON Web Token JWT implementation. In 6.2.4, fast-jwt can classify raw serialized public JWK or JWKS JSON as an HMAC secret because src/crypto.js performDetectPublicKeyAlgorithms treats non-PEM strings as symmetric key material. If HS256 is explicitly allowed or inferred, a...

fast-jwt: createVerifier accepts unsigned JWTs when key is '' or null and algorithms is explicitly set

Summary createVerifier in fast-jwt ≤ 6.3.0 skips signature verification entirely when the key option is a falsy synchronous value '' or null and the algorithms option is set to a non-empty allowlist. An attacker who can present a JWT to the application — regardless of algorithm — can forge...

Summary fast-jwt 6.2.4 silently classifies raw serialized public JWK JSON as an HMAC secret. If an application supplies public JWK JSON text as the verifier key and HS256 is explicitly allowed or automatically inferred, an attacker who knows the same public JSON text can use it as an HMAC key and...
