Starting in versions 6.3-rc-1 and 6.2.4, it's possible to inject arbitrary wiki syntax including Groovy, Python and Velocity script macros via the `newThemeName` request parameter (URL parameter), in combination with additional parameters. This has been patched in the supported versions 13.10.10, 14.9-rc-1, and 14.4.6. As a workaround, it is possible to edit `FlamingoThemesCode.WebHomeSheet` and manually perform the changes from the patch fixing the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-94","CWE-95"],"references":["https://github.com/xwiki/xwiki-platform/commit/ea2e615f50a918802fd60b09ec87aa04bc6ea8e2#diff-e2153fa59f9d92ef67b0afbf27984bd17170921a3b558fac227160003d0dfd2aR283-R284","https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-x2qm-r4wx-8gpg","https://jira.xwiki.org/browse/XWIKI-19757","https://github.com/xwiki/xwiki-platform/commit/ea2e615f50a918802fd60b09ec87aa04bc6ea8e2#diff-e2153fa59f9d92ef67b0afbf27984bd17170921a3b558fac227160003d0dfd2aR283-R284","https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-x2qm-r4wx-8gpg"],"products":["xwiki:xwiki"],"source":"nvd","synced_at":"2026-10-19T21:37:41.955480748+00:00"},"epss":{"cve":"CVE-2023-26477","score":0.74757,"percentile":0.99504,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-x2qm-r4wx-8gpg","url":"https://osv.dev/vulnerability/GHSA-x2qm-r4wx-8gpg","summary":"org.xwiki.platform:xwiki-platform-flamingo-theme-ui Eval Injection vulnerability","modified":"2026-09-10T03:49:53.300130596Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-flamingo-theme-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-flamingo-theme-ui","ranges":[">=6.2.4 <13.10.10"],"fixed":["13.10.10"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-flamingo-theme-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-flamingo-theme-ui","ranges":[">=14.0 <14.4.6"],"fixed":["14.4.6"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-flamingo-theme-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-flamingo-theme-ui","ranges":[">=14.5 <14.9-rc-1"],"fixed":["14.9-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).
