CVE-2026-65630

The potatosalad jose library (versions 1.10.0 before 1.11.13 ) contains an Observable Timing Discrepancy (CWE-208) in its pure-Erlang Curve25519 fallback. The vulnerability arises because the recursive Montgomery ladder uses value-dependent Erlang bignum arithmetic (multiplication, remainder, and...

EEF-CVE-2026-65630 Timing side-channel in pure-Erlang X25519 scalar multiplication leaks the private key in jose

Summary Observable Timing Discrepancy vulnerability in potatosalad jose allows recovery of a long-term X25519 private key through a timing side channel in the pure-Erlang Curve25519 fallback. The pure-Erlang X25519 implementation performs scalar multiplication over the secret private key using a...

CVE-2026-65629

The jose library (versions 1.10.0 to before 1.11.13) is vulnerable to an offline password-cracking attack due to weak PBKDF2 parameters used during private-key export via jose_jwk:to_der/2. The jose_jwk_der:to_binary/3 function in src/jwk/jose_jwk_der.erl uses a hardcoded iteration count of 2048 ...

EEF-CVE-2026-65629 Weak PBKDF2 parameters for password-encrypted private-key export in jose
