Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache CXF's cxf-rt-transports-http package is affected in versions 4.0.0 up to 4.0.5 and 3.6.0 up to 3.6.4. A CXF HTTP client conduit can keep HTTPClient instances from being garbage collected, so memory use can keep growing until the application runs out of memory. The source does not say what an attacker would need to trigger this. Upgrade to version 4.0.5 or 3.6.4.
