{"schemaVersion":3,"id":"CVE-2026-104714","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Concurrent execution using shared resource with improper synchronization ('race condition') vulnerability in Apache Struts. Where a localized message formats a date or time argument, the formatter retained for that message by the application-wide text provider is used by concurrently served requests without isolation, so a value belonging to one user can appear in another user's response, or the rendering can fail and surface as a server error. Applications whose localized messages format no date or time arguments 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.","dates":{"published":"2026-10-05T18:36:49.472Z","modified":"2026-10-06T14:13:46.615Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.8,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.8,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.8,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00684,"percentile":0.51681,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-06T00:00:00.000Z","score":0.00176,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00489,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00489,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00684,"percentile":0.51681}],"last30":[{"date":"2026-10-06T00:00:00.000Z","score":0.00176,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00489,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00489,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00684,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00684,"percentile":0.51681}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-362","name":"Concurrent
