GHSA-Q97C-8QH3-FPC6 phpseclib — non-constant-time X25519 scalar multiplication permits full private-key recovery
The pure-PHP X25519 scalar multiplication in phpseclib is not constant-time. Field addition and subtraction each perform a data-dependent conditional modular reduction, so the cost of each Montgomery-ladder step is a linear function of that step's reduction count which is a quantity determined by...

CVE-2026-84308
phpseclib , a PHP secure communications library, has a non-constant-time X25519 scalar multiplication flaw in versions prior to 3.0.57 and 4.0.1 . The root cause is data-dependent conditional modular reductions in the pure-PHP implementation (Math/PrimeField/Integer.php), which leak per-step timi...

Astra Linux – Vulnerability in openssl1.0
There is an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are...
