{"id":"CVE-2023-23624","state":"PUBLISHED","title":"Discourse's exclude_tags param could leak which topics had a specific hidden tag","description":"Discourse is an open-source discussion platform. Prior to version 3.0.1 on the `stable` branch and version 3.1.0.beta2 on the `beta` and `tests-passed` branches, someone can use the `exclude_tag param` to filter out topics and deduce which ones were using a specific hidden tag. This affects any Discourse site using hidden tags in public categories. This issue is patched in version 3.0.1 on the `stable` branch and version 3.1.0.beta2 on the `beta` and `tests-passed` branches. As a workaround, secure any categories that are using hidden tags, change any existing hidden tags to not include private data, or remove any hidden tags currently in use.","publishedAt":"2023-01-27T23:35:10.242Z","updatedAt":"2025-03-10T21:17:55.270Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["discourse discourse"],"affected":[{"vendor":"discourse","product":"discourse","versions":[{"version":"< 3.0.1","status":"affected"},{"version":"= 3.1.0.beta1","status":"affected"}]}],"references":["https://github.com/discourse/discourse/security/advisories/GHSA-qgj5-g5vf-fm7q","https://github.com/discourse/discourse/pull/20006","https://github.com/discourse/discourse/commit/f55e0fe7910149c431861c18ce407d1be0d6091a"],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T20:05:43.909Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/23xxx/CVE-2023-23624.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-23624","state":"PUBLISHED","datePublished":"2023-01-27T23:35:10.242Z","dateUpdated":"2025-03-10T21:17:55.270Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-01-16T17:07:46.243Z"},"containers":{"cna":{"title":"Discourse's exclude_tags param could leak which topics had a specific hidden tag","descriptions":[{"lang":"en","value":"Discourse is an open-source discussion platform.
