{"cve":"CVE-2025-66473","nvd":{"published":"2025-12-10T22:16:27.850","modified":"2026-09-25T23:10:00.463","status":"Analyzed","description":"XWiki is an open-source wiki software platform. Versions 16.10.10 and below, 17.0.0-rc-1 through 17.4.3 and 17.5.0-rc-1 through 17.6.0 contain a REST API which doesn't enforce any limits for the number of items that can be requested in a single request at the moment. Depending on the number of pages in the wiki and the memory configuration, this can lead to slowness and unavailability of the wiki. As an example, the /rest/wikis/xwiki/spaces resource returns all spaces on the wiki by default, which are basically all pages. This issue is fixed in versions 17.4.4 and 16.10.11.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://github.com/xwiki/xwiki-platform/commit/e3c47745195fb445b054537be86f5c01ee69558b","https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-cc84-q3v3-mhgf","https://jira.xwiki.org/browse/XWIKI-23355","https://jira.xwiki.org/browse/XWIKI-23355"],"products":["xwiki:xwiki"],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-66473","score":0.00403,"percentile":0.34537,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cc84-q3v3-mhgf","url":"https://osv.dev/vulnerability/GHSA-cc84-q3v3-mhgf","summary":"XWiki's REST APIs don't enforce any limits, leading to unavailability and OOM in large wikis","modified":"2025-12-11T16:22:22.102766Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-rest-server","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-rest-server","ranges":["<16.10.11"],"fixed":["16.10.11"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-rest-server","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-rest-server","ranges":[">=17.0.0-rc-1 <17.4.4"],"fixed":["17.4.4"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-rest-server","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-rest-server","ranges":[">=17.5.0-rc-1 <17.7.0-rc-1"],"fixed":["17.7.0-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).
