GHSA-W3JG-PJXF-73P4 Russh: Missing X25519 zero-point validation in hybrid ML-KEM key exchange

Vulnerability The hybrid ML-KEM 768 + X25519 key exchange implementation in russh/src/kex/hybridmlkem.rs does not validate that the remote peer's X25519 public key is not the zero point all-zero 32-byte value. This allows a remote peer to force the X25519 contribution to the combined shared secre...

CVE-2026-84308

A flaw was found in phpseclib, a PHP secure communications library. This vulnerability arises from non-constant-time X25519 scalar multiplication, where data-dependent conditional modular reductions create observable timing differences or variations in libgmp call counts. A local attacker, capabl...

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...
