Prior to version 3.0.1 of the `stable` branch and version 3.1.0.beta2 of the `beta` and `tests-passed` branches, the count of topics displayed for a tag is a count of all regular topics regardless of whether the topic is in a read restricted category or not. As a result, any users can technically poll a sensitive tag to determine if a new topic is created in a category which the user does not have excess to. \n\nIn version 3.0.1 of the `stable` branch and version 3.1.0.beta2 of the `beta` and `tests-passed` branches, the count of topics displayed for a tag defaults to only counting regular topics which are not in read restricted categories. Staff users will continue to see a count of all topics regardless of the topic's category read restrictions.","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/105fee978d73b0ec23ff814a09d1c0c9ace95164","https://github.com/discourse/discourse/commit/ecb9aa5dba94741d9579f4f873f0675f48b4184f","https://github.com/discourse/discourse/pull/20004","https://github.com/discourse/discourse/pull/20005","https://github.com/discourse/discourse/security/advisories/GHSA-2wvr-4x7w-v795"],"products":["discourse:discourse"],"source":"nvd","synced_at":"2026-10-19T21:37:41.955480748+00:00"},"epss":{"cve":"CVE-2023-23622","score":0.00534,"percentile":0.45131,"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).
