CVE-2026-102266

A flaw was found in pyjwt. A remote attacker can forge authentication tokens and bypass security controls by signing tokens with an empty key. When verifying tokens against a JSON Web Key JWK set that contains an empty Hash-based Message Authentication Code HMAC key, the library fails to enforce...

CVE-2026-97025

The Flatpak application is vulnerable to a local information disclosure flaw where it writes the OCI repository authentication token with world-readable permissions (0644 ) in the system-helper's cache directory. This allows other local users on a multi-user system to read the token and impersona...

CVE-2026-97025 Flatpak: flatpak: world-readable oci authentication token in system-helper cache path

Flatpak writes the OCI repository authentication token with world-readable permissions 0644 in the system-helper's cache directory, allowing other local users on a multi-user system to read the token and impersonate the authenticated user against the OCI repository. Only OCI-based sources e.g. as...

CVE-2026-102275

PyJWT is a Python implementation of JSON Web Token standards. From 2.1.0 until 2.15.0, PyJWT OKPAlgorithm.fromjwk in jwt/algorithms.py is affected because private-JWK import path does not compare the public key derived from d with x. This occurs when an OKP private JWK supplies non-corresponding ...

CVE-2026-102273

The PyJWT Python library (versions 2.13.0 through 2.14.0 ) contains a vulnerability in HMACAlgorithm.prepare_key . The flaw occurs because the HMAC key guard fails to recognize container representations, allowing public JWK containers to be accepted as HMAC secrets when an application supports bo...

EUVD-2026-88541

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because HMAC key guard only recognizes top-level public JWK forms and misses container representations. This occurs when an application allows HMAC and asymmetric...

CVE-2026-102273 PyJWT accepts public JWK containers as HMAC secrets

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because HMAC key guard only recognizes top-level public JWK forms and misses container representations. This occurs when an application allows HMAC and asymmetric...

CVE-2026-102272 PyJWT BOM Bypass

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.preparekey in jwt/algorithms.py is affected because raw-JWK detector does not normalize accepted Unicode byte-order marks before checking for JSON. This occurs when a public JWK is prefixed with ...

CVE-2026-102272 PyJWT BOM Bypass

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

CVE-2026-102272

The PyJWT library (versions 2.13.0 up to 2.14.0) contains a vulnerability in the HMACAlgorithm.prepare_key function within jwt/algorithms.py. The root cause is that the raw-JWK detector fails to normalize accepted Unicode byte-order marks (BOM) before performing JSON checks. When a public JWK is ...

CVE-2026-102271

The PyJWT Python library (versions 2.4.0 through 2.14.0 ) is vulnerable in the HMACAlgorithm.prepare_key function. The root cause is that the asymmetric-key guard relies on textual markers that are missing from DER encoding . When an application mixes HMAC and asymmetric algorithms and provides a...

CVE-2026-102271 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.preparekey is affected because asymmetric-key guard relies on textual markers that are absent from DER encoding. This occurs when an application mixes HMAC and asymmetric algorithms and...
