CVE-2026-41407 OpenClaw < 2026.4.2 - Timing Side Channel in Shared-Secret Comparison

OpenClaw before 2026.4.2 contains a timing side channel vulnerability in shared-secret comparison call sites that use early length-mismatch checks instead of fixed-length comparison helpers. Attackers can measure timing differences to leak secret-length information, weakening constant-time handli...

CVE-2026-41407

OpenClaw has a timing side-channel vulnerability in shared-secret comparisons. The issue occurs in call sites that use early length-mismatch checks instead of the fixed-length comparison helper, weakening constant-time handling for shared secrets. Affected software: OpenClaw prior to 2026.4.2 (np...

GHSA-PQF5-4PQQ-29F5 rust-openssl: Deriver::derive and PkeyCtxRef::derive can overflow short buffers on OpenSSL 1.1.1

Deriver::derive and PkeyCtxRef::derive sets len = buf.len and passes it as the in/out length to EVPPKEYderive, relying on OpenSSL to honor it. On OpenSSL 1.1.x, X25519, X448, DH and HKDF-extract ignore the incoming keylen, unconditionally writing the full shared secret 32/56/prime-size bytes. A...

OpenClaw: Concurrent async auth attempts can bypass the intended shared-secret rate-limit budget on Tailscale-capable paths

Impact Concurrent async auth attempts can bypass the intended shared-secret rate-limit budget on Tailscale-capable paths. Concurrent asynchronous shared-secret auth attempts could race the per-key rate-limit budget. OpenClaw is a user-controlled local assistant. This advisory is scoped to the...

OpenClaw: Shared-secret comparison call sites leaked length information through timing

Summary Before OpenClaw 2026.4.2, several shared-secret comparison call sites still used early length-mismatch checks instead of the shared fixed-length comparison helper. Those paths could leak secret-length information through measurable timing differences. Impact The affected paths exposed a...

CVE-2026-34872

A flaw was found in Mbed TLS and TF-PSA-Crypto. This vulnerability, stemming from improper input validation in the finite-field Diffie-Hellman FFDH key exchange, allows a remote attacker to force the shared secret into a small, predictable set of values. This lack of contributory behavior can...

CVE-2026-34872

An issue was discovered in Mbed TLS 3.5.x and 3.6.x through 3.6.5 and TF-PSA-Crypto 1.0. There is a lack of contributory behavior in FFDH due to improper input validation. Using finite-field Diffie-Hellman, the other party can force the shared secret into a small set of values lack of contributor...
