In affected versions a user logged as an administrator can call arbitrary methods on the `SiteSetting` class, notably `#clear_cache!` and `#notify_changed!`, which when done on a multisite instance, can affect the entire cluster resulting in a denial of service. Users not running in multisite environments are not affected. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. Users are advised to upgrade. There are no known workarounds for this vulnerability."}], "lastModified": "2023-04-28T03:50:43.710", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:discourse:discourse:*:*:*:*:stable:*:*:*", "vulnerable": true, "matchCriteriaId": "618BD7ED-B602-46C3-AFDA-55544B4E6264", "versionEndIncluding": "3.0.1"}, {"criteria": "cpe:2.3:a:discourse:discourse:*:*:*:*:beta:*:*:*", "vulnerable": true, "matchCriteriaId": "D3C08972-822D-4657-9B6F-02BC692B7C6E", "versionEndExcluding": "3.1.0"}, {"criteria": "cpe:2.3:a:discourse:discourse:3.1.0:beta1:*:*:beta:*:*:*", "vulnerable": true, "matchCriteriaId": "B9BBED17-A6BA-4F17-8814-8D8521F28375"}, {"criteria": "cpe:2.3:a:discourse:discourse:3.1.0:beta2:*:*:beta:*:*:*", "vulnerable": true, "matchCriteriaId": "888B8ECF-EBE0-4821-82F6-B0026E95E407"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
