CVE-2026-58426

Gitea Actions artifact signed URL context confusion

Gitea

This vulnerability affects Gitea Actions Artifacts V4 signed URL handling for UploadArtifact and DownloadArtifact.

An attacker able to run an Actions job could obtain a valid signed URL for their own artifact, rewrite selected context fields and make the unauthenticated endpoint operate in another task or repository context.

CVE-2026-24791

public-only token bypass in Gitea self routes

Gitea

This vulnerability affects Gitea access tokens and OAuth grants marked as public-only.

Some authenticated self routes under /api/v1/user/... did not enforce the public-resource boundary, allowing a token with the required scope to read or modify private account resources.

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.

Score

High
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.

Critical
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.

Score

High
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.
