Starting in version 2.17.1 and prior to version 2.18.2, anyone with VIEW access to a user profile can create a token for that user. If that XWiki instance is configured to allow token authentication, it allows authentication with any user (since users are very commonly viewable, at least to other registered users). Version 2.18.2 contains a patch. As a workaround, disable token access.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2},"cvss_v3":null,"cwes":["CWE-285"],"references":["https://github.com/xwiki-contrib/oidc/commit/d90d717172283aaa96bb5bb44e357f910ae64adb","https://github.com/xwiki-contrib/oidc/security/advisories/GHSA-f2hf-pfrj-vrm7","https://jira.xwiki.org/browse/OIDC-240","https://www.vicarius.io/vsociety/posts/cve-2025-49594-detect-xwiki-vulnerability","https://www.vicarius.io/vsociety/posts/cve-2025-49594-mitigate-xwiki-vulnerability"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2025-49594","score":0.00442,"percentile":0.3813,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-f2hf-pfrj-vrm7","url":"https://osv.dev/vulnerability/GHSA-f2hf-pfrj-vrm7","summary":"XWiki OIDC Authenticator: Users with \"view\" access can create tokens for any users they can view","modified":"2025-10-23T17:43:47Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.contrib.oidc:oidc-authenticator","purl":"pkg:maven/org.xwiki.contrib.oidc/oidc-authenticator","ranges":[">=2.17.1 <2.18.2"],"fixed":["2.18.2"]}]}],"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).
