If the application is configured to use the legacy RESTful action mapper, a crafted request can inject an OGNL expression that may lead to remote code execution.

Applications using the default action mapper, the restful2 mapper, or the Struts REST plugin are not affected.\n\nThis issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0.\n\nUsers are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue.","categories":["Frameworks"],"product":"Apache Struts","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104711","source_modified_at":"2026-10-06T14:09:06.711Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Apache Struts","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"2.0.0","lessThanOrEqual":"2.3.37","versionType":"semver"},{"status":"affected","version":"2.5.0","lessThanOrEqual":"2.5.33","versionType":"semver"},{"status":"affected","version":"6.0.0","lessThanOrEqual":"6.11.0","versionType":"semver"},{"status":"affected","version":"7.0.0","lessThanOrEqual":"7.3.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":9.8,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.01191,"percentile":0.67759,"score_date":"2026-10-23"},"published_at":"2026-10-05T18:35:10.026Z","modified_at":"2026-10-06T14:09:06.711Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104711","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-06T14:09:06.711Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104711","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://cwiki.apache.org/confluence/display/WW/S2-075","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"total","assessed_at":"2026-10-06T14:08:35.909211Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-06T14:09:06.711Z","content_hash":"f3d6798750acee8edba15f35a1cc9defa4d10b73359ee5762d3737432d0fea6a"}}
