Then, click on any operation (*e.g.,* Trigger) on any job. If the operation is successful, then the instance is vulnerable.\n\n### Patches\nThis has been patched in XWiki 15.10.9 and 16.3.0.\n\n### Workarounds\nIf you have subwikis where the Job Scheduler is enabled, you can edit the objects on `Scheduler.WebPreferences` to match https://github.com/xwiki/xwiki-platform/commit/54bcc5a7a2e440cc591b91eece9c13dc0c487331#diff-8e274bd0065e319a34090339de6dfe56193144d15fd71c52c1be7272254728b4.\n\n### References\n* https://jira.xwiki.org/browse/XWIKI-21663\n* https://github.com/xwiki/xwiki-platform/commit/54bcc5a7a2e440cc591b91eece9c13dc0c487331\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [Jira XWiki.org](https://jira.xwiki.org/)\n* Email us at [Security Mailing List](mailto:security@xwiki.org)","published":"2024-12-12T18:59:49.733Z","modified":"2026-08-12T15:15:44.262115Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L"},"epss":{"score":0.00564,"percentile":0.43935,"asOf":"2026-08-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-scheduler-ui","fixedVersion":"15.10.9"},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-scheduler-ui","fixedVersion":"16.3.0"}],"fix":{"url":"https://github.com/xwiki/xwiki-platform/commit/54bcc5a7a2e440cc591b91eece9c13dc0c487331","label":"xwiki/xwiki-platform@54bcc5a"},"references":[{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-21663"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/55xxx/CVE-2024-55876.json"},{"type":"ADVISORY","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-cwq6-mjmx-47p6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-55876"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-platform/commit/54bcc5a7a2e440cc591b91eece9c13dc0c487331"},{"type":"PACKAGE","url":"https://github.com/xwiki/xwiki-platform"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T15:15:44.262115Z"}}
