CVE-2026-53939 OpenIDC/cjose uses all-zero Content Encryption Key for AES-CBC-HMAC JWE encryption

OpenIDC/cjose is a C library implementing the Javascript Object Signing and Encryption JOSE. In versions 0.6.1 through 0.6.2.5, when cjose encrypts a JWE using an AES-CBC-HMAC content-encryption algorithm A128CBC-HS256, A192CBC-HS384, or A256CBC-HS512 together with any key-management algorithm th...
