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. Check out the EPSS documentation for more details.

NewCVE-2026-81703 (opens in a new tab)How to fix?
Upgrade openssl-encrypt to version 1.4.9 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 Improper Authentication via the openssl_encrypt process. An attacker can gain unauthorized access by crafting files containing unencrypted embedded post-quantum cryptographic keys, which are accepted without proper validation and allow decryption under any password, resulting in attacker-controlled plaintext and false integrity verification.
