CVE-2026-53622

HTTP/3 mTLS bypass in Traefik router TLSOptions selection

Traefik

This vulnerability affects Traefik deployments with HTTP/3 enabled and router-specific TLSOptions used as an mTLS boundary.

An unauthenticated client could complete QUIC/TLS without a client certificate and still reach a backend the operator expected to be mTLS-protected.

CVE-2026-49980

rclone rc --rc-serve inline remote backend instantiation

rclone

This issue affects the GET/HEAD path in `rclone rcd --rc-serve` when the RC listener was reachable without global HTTP authentication.

A request could force backend creation from an inline remote, leading to local file read or command execution as the rclone process user depending on version.

CVE-2026-49284

ExpectedIssuer and InResponseTo binding bypass in SimpleSAMLphp

SimpleSAMLphp

This vulnerability concerns SAML SP login-state binding in SimpleSAMLphp deployments with multiple IdPs.

A response from a different trusted IdP could be accepted for state created for the expected IdP when `InResponseTo` binding was not cryptographically carried by the signed assertion.

CVE-2026-49283

HTTP-Artifact TLS validator confusion in SimpleSAMLphp SAML2

SimpleSAMLphp SAML2

This issue affects HTTP-Artifact validation in the SimpleSAMLphp SAML2 and SAML2 Legacy libraries.

An ArtifactResponse obtained from one IdP could validate an embedded SAML Response claiming another issuer, creating an authentication-bypass risk in multi-IdP deployments.

CVE-2026-48774

MCP run_sql_readonly multi-statement bypass in ProxySQL

ProxySQL

This vulnerability affects ProxySQL's MCP `run_sql_readonly` tool, which was intended to enforce read-only SQL queries.

Validation checked the full string with a weak blacklist but executed the original SQL on a MySQL multi-statement connection, allowing a second state-changing statement.

CVE-2026-48773

pre-auth first-packet heap overflow in ProxySQL

ProxySQL

This issue affects ProxySQL MySQL and PostgreSQL frontend first-packet handling before authentication.

A remote client could declare an oversized packet length, causing a heap out-of-bounds write before later protocol validation could reject the connection.

CVE-2026-48491

Domain-fronted mTLS bypass in Traefik SNICheck wildcard TLSOptions

Traefik

This vulnerability affects Traefik wildcard router TLSOptions on the regular HTTPS/HTTP2 path.

A client could use a permissive SNI during the TLS handshake and then send a Host value targeting the wildcard mTLS-protected backend, reaching it without the required client certificate.

CVE-2026-46491

Path traversal in SimpleSAMLphp casserver FileSystemTicketStore

SimpleSAMLphp casserver

This vulnerability affects the file-based CAS ticket store in `simplesamlphp-module-casserver`.

Attacker-controlled ticket identifiers were used as filesystem path components, allowing traversal outside the ticket directory and, under specific conditions, file read, unserialization or deletion.
