Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Struts Extras (org.apache.struts:struts-extras) up to and including 1.3.10, and struts:struts version 1.2.9, are affected. When LookupDispatchAction is used, untrusted input can be written to logs without filtering, so an attacker who can supply such input can forge log lines that confuse human or automated log readers. No fix is listed because the project is retired; the source recommends finding an alternative or restricting access to trusted users.
