openssl-encrypt has non-cryptographic PRNG used for steganography pixel selection

Summary The generatepseudorandomsequence function in opensslencrypt/plugins/steganography/core/utils.py at lines 89-91 uses Python's random module Mersenne Twister for steganographic pixel/sample selection. Affected Code python random.seedseed sequence = random.samplerangemaxvalue, minlength,...

CVE-2026-21713

A flaw was found in Node.js. The HMAC Hash-based Message Authentication Code verification process uses a comparison method that does not take a constant amount of time. This non-constant-time comparison can leak timing information, which, under specific conditions where precise timing measurement...

CVE-2026-4662

The JetEngine plugin for WordPress is vulnerable to SQL Injection via the listingloadmore AJAX action in all versions up to, and including, 3.8.6.1. This is due to the filteredquery parameter being excluded from the HMAC signature validation allowing attacker-controlled input to bypass security...

Observable Timing Discrepancy

Overview Affected versions of this package are vulnerable to Observable Timing Discrepancy due to the cryptohmac.cc module using memcmp, a non-constant-time comparison function to validate user-provided HMAC signatures, rather than the timing-safe equivalents used elsewhere in the codebase. An...
