    Action Type Old Value New Value
    Added Tag unsupported-when-assigned
    Added Description ** UNSUPPORTED WHEN ASSIGNED ** Improper Output Neutralization for Logs vulnerability in Apache Struts.

    This issue affects Apache Struts Extras: before 2.

    When using LookupDispatchAction, in some cases, Struts may print untrusted input to the logs without any filtering. Specially-crafted input may lead to log output where part of the message masquerades as a separate log line, confusing consumers of the logs (either human or automated). 

    As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.

    NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

    Added CWE CWE-117
