NVD Description

Note: Versions mentioned in the description apply only to the upstream wso2is package and not the wso2is package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

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.
