CVE-2026-57819

CVE-2026-57819 affects Apache CXF; there is no default limit on the number of form parameters per JAX-RS message due to the maxFormParameterCount setting. This can enable denial-of-service when processing requests with many form parameters. The connected sources state fixes by introducing a defau...

EUVD-2026-53851

Apache CXF allows to control the maximum attachment size via the "attachment-max-size". Prior to Apache CXF 4.2.3 and 4.1.8 and 3.6.12, there was no default placed on this size, meaning that a denial of service attack is possible if the user doesn't explicitly set the limit. Users should update t...
