Russh is a Rust SSH client & server library. From version 0.34.0-beta.1 to before version 0.61.0, the russh server authentication path keeps internal userauth state across SSHMSGUSERAUTHREQUEST messages without separating that state when the request principal changes. RFC 4252 allows the user nam...

curl: curl GnuTLS backend accepts a clientAuth-only certificate for HTTPS server authentication
Summary: When curl/libcurl is built with the GnuTLS backend, the current HTTPS server-certificate validation path verifies the trust chain and hostname but does not enforce TLS server Extended Key Usage semantics. As a result, a leaf certificate that chains to a trusted CA, matches the requested...
OSEC-2026-06 TLS-client (with TLS 1.3) does insufficient certificate checks (missing KeyUsage and ExtendedKeyUsage validation)
The ocaml-TLS 1.3 client does not validate the KeyUsage and ExtendedKeyUsage extensions of the server certificate. This can lead to impersonation with a certificate issued to a client. Scenario Every employee at a major bank carries a smart card. The card holds a clientAuth certificate issued by...

Name of the Vulnerable Software and Affected Versions OCaml-TLS versions prior to 2.1.0 Description The client implementation in OCaml-TLS fails to properly validate the KeyUsage and ExtendedKeyUsage EKU extensions of server certificates during TLS 1.3 handshakes. Specifically, the answer...
curl: Schannel custom-CA path skips Extended Key Usage enforcement
Hi all, We believe the Schannel custom-CA verification path in lib/vtls/schannelverify.c may skip Extended Key Usage enforcement. In particular, a certificate that chains to the trusted custom CA but contains only id-kp-clientAuth, rather than id-kp-serverAuth, may pass peer verification on Windo...
