Description
CVE-2026-65629 is a vulnerability in the potatosalad jose library versions from 1.10.0 up to but not including 1.11.13. It involves the use of a password hash with insufficient computational effort during the export of password-encrypted private keys. The key derivation uses PBKDF2-HMAC-SHA256 with only 2048 iterations and a 64-bit salt, both far below current security recommendations. This weakness allows an attacker who obtains an exported encrypted private key to perform an offline password-cracking attack to recover the private key.
