In affected versions a vulnerability affects users of tag groups who use the \"Tags are visible only to the following groups\" feature. A tag group may only allow a certain group (e.g. staff) to view certain tags. Users who were tracking or watching the tags via /preferences/tags, then have their staff status revoked will still see notifications related to the tag, but will not see the tag on each topic. This issue has been patched in stable version 2.7.11. Users are advised to upgrade as soon as possible.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-200"],"references":["https://github.com/discourse/discourse/commit/cdaf7f4bb3ec268238e4c29a14bb73fad56574b4","https://github.com/discourse/discourse/security/advisories/GHSA-pq2x-vq37-8522","https://meta.discourse.org/t/non-forum-staff-getting-notifications-for-staff-only-tags/184895","https://github.com/discourse/discourse/commit/cdaf7f4bb3ec268238e4c29a14bb73fad56574b4","https://github.com/discourse/discourse/security/advisories/GHSA-pq2x-vq37-8522"],"products":["discourse:discourse"],"source":"nvd","synced_at":"2026-10-19T21:25:41.256909649+00:00"},"epss":{"cve":"CVE-2021-43792","score":0.00857,"percentile":0.58442,"date":"2026-10-31"},"kev":null,"osv":[],"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).
