CVE-2025-54887 jwe: Missing AES-GCM authentication tag validation in encrypted JWEs

jwe is a Ruby implementation of the RFC 7516 JSON Web Encryption JWE standard. In versions 1.1.0 and below, authentication tags of encrypted JWEs can be brute forced, which may result in loss of confidentiality for those JWEs and provide ways to craft arbitrary JWEs. This puts users at risk becau...

CVE-2025-54887

CVE-2025-54887 affects the Ruby library jwe (Ruby implementation of RFC 7516) in versions 1.1.0 and earlier. The auth tag of encrypted JWEs can be brute-forced, enabling modification of JWEs to yield arbitrary plaintext and potentially revealing the GHASH key, which requires rotating keys after u...

JWE 安全漏洞

JWE is a Ruby-based JSON Web encryption library from JSON Web Token open source. A security vulnerability exists in JWE 1.1.0 and earlier versions, which stems from the fact that the authentication tag that encrypts JWE can be brute-force broken, potentially resulting in a loss of confidentiality...
