Summary
The fence-agents packages provide a collection of scripts for handling remote power management for cluster devices. They allow failed or unreachable nodes to be forcibly restarted and removed from the cluster.
Security Fix(es):
* pyjwt: pyjwt: Authentication bypass via empty HMAC key acceptance (CVE-2026-102266)
* pyjwt: PyJWT: Authentication bypass via improper public key validation (CVE-2026-102268)
* pyjwt: PyJWT: Authentication bypass via acceptance of DER public keys as HMAC secrets (CVE-2026-102271)
* pyjwt: pyjwt: Verification key substitution via unvalidated JWKS redirects (CVE-2026-102267)
* pyjwt: pyjwt: Token forgery via improper Unicode byte-order mark handling (CVE-2026-102272)

Critical 9.1CVE-2026-102268 Public exploit
PyJWT: Asymmetric-PEM detection bypass: whitespace/line-ending-mutated public keys skip the HS/asymmetric confusion guard
PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, is_pem_format in jwt/utils.py is affected because is_pem_format does not recognize every PEM representation accepted by the cryptography loader. This occurs when an application mix…

High 7.4
PyJWK accepts empty HMAC keys, bypassing PyJWT's empty-key validation
PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.from_jwk is affected because PyJWK verification path used the decoded key without applying prepare_key validation. This occurs when a trusted JWK Set contain…

High 7.4
PyJWT: PyJWKClient follows redirects when fetching JWKS
PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT PyJWKClient is affected because redirect destinations are not revalidated against the JWKS trust boundary. This occurs when a configured trusted JWKS endpoint returns an atta…

High 7.4
PyJWT: Public keys in DER form are accepted as HMAC secrets, bypassing the CVE-2022-29217 guard
PyJWT is a Python implementation of JSON Web Token standards. From 2.4.0 until 2.14.0, PyJWT HMACAlgorithm.prepare_key is affected because asymmetric-key guard relies on textual markers that are absent from DER encoding. This occurs when an application mixes …

High 7.4
PyJWT BOM Bypass
PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.prepare_key in jwt/algorithms.py is affected because raw-JWK detector does not normalize accepted Unicode byte-order marks before checking for JSON. This occ…
