CVE-2026-50645

7.5 high SSVC exploitation: none Modified
NVD · CVE.org

There is no restriction on the amount of attachment headers that a message can contain when being deserialized by Apache CXF, which can lead to uncontrolled resource consumption or a denial of service attack. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this issue by imposing a maximum default of 500 attachments per message.
