Severity: low Affected versions:
- Apache CXF (org.apache.cxf:cxf-core) 4.2.0 before 4.2.2 - Apache CXF (org.apache.cxf:cxf-core) before 4.1.7 Description: 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, which fix this issue by imposing a maximum default of 500 attachments per message.
