CVE-2026-81704 openssl_encrypt before 1.4.9 Weak Key Derivation via D-Bus

opensslencrypt versions before 1.4.9 contain a weak key derivation vulnerability in the D-Bus CryptoService.EncryptFile handler that uses unstretched SHA-256 instead of Argon2id. Attackers can perform offline password guessing against encrypted files roughly six to seven orders of magnitude faste...

CVE-2026-81704

openssl_encrypt versions before 1.4.9 contain a weak key derivation vulnerability in the D-Bus CryptoService.EncryptFile handler. The affected code uses unstretched SHA-256 instead of Argon2id , omitting key stretching and hash rounds. This allows attackers to perform offline password guessing ag...

CVE-2026-81703 openssl_encrypt before 1.4.9 Authentication Bypass via Unencrypted PQC Key

opensslencrypt versions before 1.4.9 fail to validate encryption status of embedded post-quantum private keys in file metadata. Attackers can craft files with unencrypted embedded PQC keys that decrypt under any password, bypassing authentication and producing attacker-chosen plaintext with false...

CVE-2026-81702

openssl_encrypt before 1.4.9 fails to re-derive and validate fingerprints when loading identities from identity.json, enabling silent key substitution . An attacker can replace legitimate public keys in identity stores with their own while maintaining the claimed fingerprint, so that encryption u...

CVE-2026-81701

openssl_encrypt versions before 1.4.9 contain an arbitrary code execution vulnerability in its plugin signature verification mechanism. The root cause is a denylist approach used to identify trusted built-in plugins: unsigned plugins placed in top-level plugins/ directories or unknown subdirector...

CVE-2026-81700 openssl_encrypt before 1.4.9 GPG Signature Verification Bypass

opensslencrypt versions before 1.4.9 contain a signature verification vulnerability in gpgrunner.verifydetached that accepts revoked and expired keys by only checking VALIDSIG status without inspecting REVKEYSIG, EXPKEYSIG, or gpg exit codes. Attackers holding compromised-then-revoked signing key...

CVE-2026-81701 openssl_encrypt before 1.4.9 Arbitrary Code Execution via unsigned plugin

opensslencrypt versions before 1.4.9 use a denylist to identify trusted built-in plugins, allowing unsigned plugins in top-level plugins/ directories and unknown subdirectories to bypass signature verification. Attackers can place malicious unsigned plugins following documented installation paths...

CVE-2026-81700

openssl_encrypt versions before 1.4.9 contain a signature verification bypass in the gpg_runner.verify_detached function. The root cause is that the function only checks the VALIDSIG status without inspecting REVKEYSIG , EXPKEYSIG , or GPG exit codes, causing it to accept revoked and expired sign...
