{"id":"CVE-2025-54656","aliases":[],"url":"https://o3.security/vulnerability/CVE-2025-54656","summary":"** UNSUPPORTED WHEN ASSIGNED ** Improper Output Neutralization for Logs vulnerability in Apache Struts.\n\nThis issue affects Apache Struts Extras: before 2.\n\nWhen using LookupDispatchAction,…","details":"** UNSUPPORTED WHEN ASSIGNED ** Improper Output Neutralization for Logs vulnerability in Apache Struts.\n\nThis issue affects Apache Struts Extras: before 2.\n\nWhen 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). \n\nAs 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.\n\nNOTE: This vulnerability only affects products that are no longer supported by the maintainer.","published":"2025-07-30T16:15:28.693","modified":"2026-06-17T09:40:29.180","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://lists.apache.org/thread/so5cn07j2zn9vlf1xnfqp630wts719rr"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/07/30/1"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-06-17T09:40:29.180"}}
