CVE-2026-81702Network attack vectorHinoki check available

Encryption redirection and signature forgery via stored fingerprint

Published Aug 27, 2026 · Updated Aug 27, 2026

Key substitution in jahlives OpenSSL Encrypt before 1.4.9 allows attackers to redirect encryption and validate forged signatures. Identity.load accepts the fingerprint stored in identity.json without recomputing it from the accompanying public-key PEM files. Attackers who can supply or modify an identity store can retain a trusted fingerprint while replacing encryption and signing keys, causing encryption to use attacker-controlled keys and forged signatures to verify.
