CVE-2026-81685Hinoki check available

Warning-text forgery via unsanitized recovery metadata

Published Aug 27, 2026 · Updated Aug 27, 2026

Output injection in OpenSSL Encrypt before 1.4.9 allows attackers to forge removal-dialog warnings through crafted encrypted files. The desktop GUI decodes unsanitized recovery-slot id and type fields into bare Text widgets, so bidi controls and U+2028/U+2029 separators can create deceptive lines. Exploitation requires a user to open the crafted file and invoke irreversible slot removal; the demonstrated consequence is a misleading confirmation prompt, not code execution or data disclosure.
