CVE-2026-74900

openssl_encrypt before version 1.4.0 has a flaw in pqc.py: when KEM decapsulation fails, it silently falls back to simulation mode, deriving a deterministic shared secret from just 16 bytes of the private key plus public encapsulated key data. An attacker with those 16 private-key bytes can compu...

CVE-2026-74894

opensslencrypt before 1.4.0 contains an authentication bypass vulnerability in the verifyapitoken function that accepts any non-empty Bearer token string without validation. Attackers can upload arbitrary public keys, enumerate all keys, and revoke keys belonging to any user by providing any Bear...

CVE-2026-74894

The PHP package openssl_encrypt before version 1.4.0 has a broken verify_api_token function that accepts any non-empty Bearer token, allowing unauthenticated attackers to upload arbitrary public keys, enumerate all keys, and revoke any user's keys. CVSS 9.8 Critical. Upgrade to 1.4.0. No in-the-w...

CVE-2026-74892

opensslencrypt versions before 1.4.0 contain a hardcoded default secret key in the standalone telemetry server configuration that is used for API key hashing. Attackers who know this default value can predict or forge API key hashes to compromise telemetry API authentication...

CVE-2026-74892

The openssl_encrypt package (versions before 1.4.0) ships a hardcoded default secret key in its standalone telemetry server configuration, used for API key hashing. Attackers who know this key can forge API key hashes to bypass telemetry API authentication. CVSS 3.1 rates this HIGH (7.5) due to r...

CVE-2026-74889 openssl_encrypt before 1.4.0 Weak Key Derivation via HKDF

opensslencrypt versions before 1.4.0 use HKDF with no salt and static info parameter in key normalization functions, reducing entropy extraction and determinism. Attackers can exploit predictable key derivation with identical inputs to weaken cryptographic security against multi-target attacks...

CVE-2026-74889

The openssl_encrypt library (PHP package) before version 1.4.0 uses HKDF with no salt and a static info parameter in its key normalization functions, producing deterministic, low-entropy derived keys. Attackers with identical inputs can predict derived keys, weakening cryptographic security again...
