Answer in brief
CVE-2026-74901 records a Unknown severity vulnerability in openssl_encrypt before 1.4.0 Authentication Bypass via AES-CTR Fallback. The current sources do not mark it as known exploited. The current feed maps jahlives/openssl_encrypt (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

openssl_encrypt versions before 1.4.0 contain an authentication bypass vulnerability in pqc.py where AES-GCM decryption failures trigger fallback to unauthenticated AES-CTR mode. Attackers can modify ciphertext in transit to bypass integrity verification and perform bit-flipping attacks without detection.
