CVE-2026-107938

The Apache CXF Netty-based HTTP client transport (cxf-rt-transports-http-netty-client ) fails to verify that the hostname in a server's TLS certificate matches the host being called. This flaw impacts both HTTP/1.1 and HTTP/2 protocols, even when the disableCNCheck parameter is set to its default...

CVE-2026-107938 Apache CXF: The Netty HTTP client transport does not perform TLS hostname verification.

In Apache CXF, the Netty-based HTTP client transport cxf-rt-transports-http-netty-client did not verify that the hostname in the server’s TLS certificate matched the host being called. This applied over both HTTP/1.1 and HTTP/2, even when disableCNCheck was left at its default value of false. The...

CVE-2026-107937 Apache CXF: The attachment header size and count limits can be bypassed, which allows denial of service through memory exhaustion.

In Apache CXF, the parser for multipart/MTOM attachment part headers did not fully enforce the configured attachment-max-header-size default 300 characters and attachment-headers-max-count default 500 limits. The size limit was applied only to each physical line, not to a header value built from...

CVE-2026-107937

In Apache CXF , the parser for multipart/MTOM attachment part headers fails to fully enforce attachment-max-header-size and attachment-headers-max-count limits. Specifically, size limits are only applied to physical lines rather than continuation lines or repeated headers, and count limits check ...

CVE-2026-97791 Apache CXF: STSTokenValidator can accept untrusted SAML assertions because it shares validation state between requests

In Apache CXF, STSTokenValidator checks whether a SAML assertion is signed by a trusted certificate before deciding to send it to the STS. That result was stored in one object shared by all requests, so one request could read another's result. A remote, unauthenticated attacker could send a forge...
