jose-swift has JWT Signature Verification Bypass via None Algorithm

Summary An authentication bypass vulnerability allows any unauthenticated attacker to forge arbitrary JWT tokens by setting "alg": "none" in the token header. The library's verification functions immediately return true for such tokens without performing any cryptographic verification, enabling...

jose-swift has JWT Signature Verification Bypass via None Algorithm

An authentication bypass vulnerability allows any unauthenticated attacker to forge arbitrary JWT tokens by setting "alg": "none" in the token header. The library's verification functions immediately return true for such tokens without performing any cryptographic verification, enabling complete...

CVE-2025-61152

python-jose thru 3.3.0 allows JWT tokens with 'alg=none' to be decoded and accepted without any cryptographic signature verification. A malicious actor can craft a forged token with arbitrary claims e.g., isadmin=true and bypass authentication checks, leading to privilege escalation or unauthoriz...

CVE-2025-61152

The vulnerability CVE-2025-61152 affects python-jose up to version 3.3.0. It allows JWT tokens signed with alg=none to be decoded and accepted without cryptographic signature verification, enabling a forged token with arbitrary claims (e.g., is_admin=true) and bypassing authentication in applicat...

CBL Mariner 2.0 Security Update: ceph (CVE-2024-48916)

The version of ceph installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-48916 advisory. - Ceph is a distributed object, block, and file storage platform. In versions 19.2.3 and below, it is possible t...

CVE-2023-22893

Strapi through 4.5.5 does not verify the access or ID tokens issued during the OAuth flow when the AWS Cognito login provider is used for authentication. A remote attacker could forge an ID token that is signed using the 'None' type algorithm to bypass authentication and impersonate any user that...
