{"id":"BIT-discourse-2022-24782","summary":"Secure category names leaked via user activity export in Discourse","details":"Discourse is an open source discussion platform. Versions 2.8.2 and prior in the `stable` branch, 2.9.0.beta3 and prior in the `beta` branch, and 2.9.0.beta3 and prior in the `tests-passed` branch are vulnerable to a data leak. Users can request an export of their own activity. Sometimes, due to category settings, they may have category membership for a secure category. The name of this secure category is shown to the user in the export. The same thing occurs when the user's post has been moved to a secure category. A patch for this issue is available in the `main` branch of Discourse's GitHub repository and is anticipated to be part of future releases.","aliases":["CVE-2022-24782","GHSA-c3cq-w899-f343"],"modified":"2026-09-08T08:46:10.352015328Z","published":"2024-03-06T11:06:48.469Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://github.com/discourse/discourse/commit/9d5737fd28374cc876c070f6c3a931a8071ec356"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/pull/16273"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-c3cq-w899-f343"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-24782"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.8.3"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2022-24782.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}],"schema_version":"1.9.0"}
