When a user logs in via the OAuth method, the identityOAuth parameters sent in the GET request is vulnerable to cross site scripting (XSS) and XWiki syntax injection. This allows remote code execution via the groovy macro and thus affects the confidentiality, integrity and availability of the whole XWiki installation. The issue has been fixed in Identity OAuth version 1.6. There are no known workarounds for this vulnerability and users are advised to upgrade.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6},"cwes":["CWE-79","CWE-94"],"references":["https://github.com/xwikisas/identity-oauth/blob/master/ui/src/main/resources/IdentityOAuth/LoginUIExtension.vm#L58","https://github.com/xwikisas/identity-oauth/commit/d805d3154b17c6bf455ddf5deb0a3461a3833bc6","https://github.com/xwikisas/identity-oauth/commit/d805d3154b17c6bf455ddf5deb0a3461a3833bc6#diff-2ab2e0716443d790d7d798320e4a45151661f4eca5440331f4a227b29c87c188","https://github.com/xwikisas/identity-oauth/security/advisories/GHSA-h2rm-29ch-wfmh","https://jira.xwiki.org/browse/XWIKI-20719"],"products":["xwiki:oauth_identity"],"source":"nvd","synced_at":"2026-10-19T21:39:34.467980132+00:00"},"epss":{"cve":"CVE-2023-45144","score":0.01235,"percentile":0.69058,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-h2rm-29ch-wfmh","url":"https://osv.dev/vulnerability/GHSA-h2rm-29ch-wfmh","summary":"XWiki Identity Oauth Privilege escalation (PR)/remote code execution from login screen through unescaped URL parameter","modified":"2023-11-08T04:13:37.383140Z","packages":[{"ecosystem":"Maven","name":"com.xwiki.identity-oauth:identity-oauth-ui","purl":"pkg:maven/com.xwiki.identity-oauth/identity-oauth-ui","ranges":[">=1.0 <1.6"],"fixed":["1.6"]}]}],"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).
