{"cve":"CVE-2023-27479","nvd":{"published":"2023-03-07T19:15:12.577","modified":"2026-06-17T05:45:17.753","status":"Modified","description":"XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions any user with view rights can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of UIX parameters. A proof of concept exploit is to log in, add an `XWiki.UIExtensionClass` xobject to the user profile page, with an Extension Parameters content containing `label={{/html}} {{async async=\"true\" cached=\"false\" context=\"doc.reference\"}}{{groovy}}println(\"Hello \" + \"from groovy!\"){{/groovy}}{{/async}}`. Then, navigating to `PanelsCode.ApplicationsPanelConfigurationSheet` (i.e., `<xwiki-host>/xwiki/bin/view/PanelsCode/ApplicationsPanelConfigurationSheet` where `<xwiki-host>` is the URL of your XWiki installation) should not execute the Groovy script. If it does, you will see `Hello from groovy!` displayed on the screen. This vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10-rc-1. Users are advised to upgrade. For users unable to upgrade the issue can be fixed by editing the `PanelsCode.ApplicationsPanelConfigurationSheet` wiki page and making the same modifications  as shown in commit `6de5442f3c`.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-74"],"references":["https://github.com/xwiki/xwiki-platform/commit/6de5442f3c91c3634a66c7b458d5b142e1c2a2dc","https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-qxjg-jhgw-qhrv","https://jira.xwiki.org/browse/XWIKI-20294","https://github.com/xwiki/xwiki-platform/commit/6de5442f3c91c3634a66c7b458d5b142e1c2a2dc","https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-qxjg-jhgw-qhrv"],"products":["xwiki:xwiki"],"source":"nvd","synced_at":"2026-10-19T21:37:41.955480748+00:00"},"epss":{"cve":"CVE-2023-27479","score":0.01144,"percentile":0.66729,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qxjg-jhgw-qhrv","url":"https://osv.dev/vulnerability/GHSA-qxjg-jhgw-qhrv","summary":"org.xwiki.platform:xwiki-platform-panels-ui vulnerable to Eval Injection","modified":"2026-09-10T03:49:57.007511727Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-panels-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-panels-ui","ranges":[">=6.3-milestone-2 <13.10.11"],"fixed":["13.10.11"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-panels-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-panels-ui","ranges":[">=14.0 <14.4.7"],"fixed":["14.4.7"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-panels-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-panels-ui","ranges":[">=14.5 <14.10-rc-1"],"fixed":["14.10-rc-1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
