{"id":"CVE-2023-37277","aliases":["GHSA-6xxr-648m-gch6"],"url":"https://o3.security/vulnerability/CVE-2023-37277","summary":"XWiki Platform vulnerable to cross-site request forgery (CSRF) via the REST API","details":"### Impact\n\nThe REST API allows executing all actions via POST requests and accepts `text/plain`, `multipart/form-data` or `application/www-form-urlencoded` as content types which can be sent via regular HTML forms, thus allowing cross-site request forgery. With the interaction of a user with programming rights, this allows remote code execution through script macros and thus impacts the integrity, availability and confidentiality of the whole XWiki installation.\n\nFor regular cookie-based authentication, the vulnerability is mitigated by SameSite cookie restrictions but as of March 2023, these are not enabled by default in Firefox and Safari.\n\n### Patches\nThe vulnerability has been patched in XWiki 14.10.8 and 15.2 by requiring a CSRF token header for certain request types that are susceptible to CSRF attacks.\n\n### Workarounds\n\nIt is possible to check for the `Origin` header in a reverse proxy to protect the REST endpoint from CSRF attacks, see [the Jira issue](https://jira.xwiki.org/browse/XWIKI-20135) for an example configuration.\n\n### References\n\n* https://jira.xwiki.org/browse/XWIKI-20135\n* https://github.com/xwiki/xwiki-platform/commit/4c175405faa0e62437df397811c7526dfc0fbae7\n","published":"2023-07-10T16:11:14.120Z","modified":"2026-08-12T14:50:49.356668Z","cvss":{"score":9.6,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},"epss":{"score":0.00669,"percentile":0.48935,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-rest-server","fixedVersion":"14.10.8"},{"ecosystem":"Maven","name":"com.xpn.xwiki.platform:xwiki-core-rest-server","fixedVersion":"14.10.8"},{"ecosystem":"Maven","name":"com.xpn.xwiki.platform:xwiki-rest","fixedVersion":"14.10.8"},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-rest-server","fixedVersion":"15.2"}],"fix":{"url":"https://github.com/xwiki/xwiki-platform/commit/4c175405faa0e62437df397811c7526dfc0fbae7","label":"xwiki/xwiki-platform@4c17540"},"references":[{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-20135"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/37xxx/CVE-2023-37277.json"},{"type":"ADVISORY","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-6xxr-648m-gch6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-37277"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-platform/commit/4c175405faa0e62437df397811c7526dfc0fbae7"},{"type":"PACKAGE","url":"https://github.com/xwiki/xwiki-platform"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T14:50:49.356668Z"}}
