When a libcurl-based application performs transfers via SCP:// or SFTP:// and utilizes the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This vulnerability occurs when a server presents a host key type that does not match the specific key type already recorded for th...

CVE-2026-9547

The CVE-2026-9547 issue affects libcurl when performing SCP/SFTP transfers with CURLOT_SSH_KEYFUNCTION in the SSH key callback. A host-key type mismatch for a known_hosts entry may be silently accepted, bypassing the intended validation and allowing connections to succeed without warning, which e...

CVE-2026-8926

CVE-2026-8926 affects curl when using a .netrc file for credentials while the URL contains a username (no password). The vulnerability can cause curl to fetch and use the password of another user for the same host if a matching host exists in .netrc, leading to credential disclosure. The issue is...

SimpleSAMLphp SP accepts a response from an unexpected IdP when unsigned `Response/InResponseTo` is combined with a signed assertion lacking `SubjectConfirmationData/InResponseTo`

Summary SimpleSAMLphp's SAML SP ACS path does not enforce the IdP selected for an SP-initiated login. If a saved SP state contains ExpectedIssuer = IdP A, but the ACS receives a valid response from IdP B, the code logs a warning and continues processing instead of rejecting the response. That...

curl: curl: Insecure connection establishment due to TLS configuration mismatch

A flaw was found in curl. When a new data transfer attempts to upgrade its connection using STARTTLS, it may incorrectly reuse an existing live connection. This reuse can occur even if the Transport Layer Security TLS configuration of the new transfer does not match the existing connection,...

curl: curl: Man-in-the-middle attack via SSH host key bypass

A flaw was found in curl. When a libcurl-based application uses SCP:// or SFTP:// for transfers and employs the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This occurs if the server's host key type differs from the one stored in the knownhosts file. The callback...
