Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

NewCVE-2026-74900 (opens in a new tab)How to fix?
Upgrade openssl-encrypt to version 1.4.0 or higher.
Overview
openssl-encrypt is an A package for secure file encryption and decryption based on modern ciphers using heavy-compute-load chaining of hashing and KDF to generate strong encryption password based on users provided password to ensure secure encryption of files
Affected versions of this package are vulnerable to Unchecked Return Value in the pqc.py process. An attacker can recover the shared secret and decrypt all ciphertext by obtaining 16 bytes of the private key and leveraging publicly available encapsulated key data, as the fallback mechanism triggers on any KEM decapsulation failure without raising an error.
