{"id":"BIT-discourse-2022-21677","summary":"Group advanced search option may leak group and group's members visibility ","details":"Discourse is an open source discussion platform. Discourse groups can be configured with varying visibility levels for the group as well as the group members. By default, a newly created group has its visibility set to public and the group's members visibility set to public as well. However, a group's visibility and the group's members visibility can be configured such that it is restricted to logged on users, members of the group or staff users. A vulnerability has been discovered in versions prior to 2.7.13 and 2.8.0.beta11 where the group advanced search option does not respect the group's visibility and members visibility level. As such, a group with restricted visibility or members visibility can be revealed through search with the right search option. This issue is patched in `stable` version 2.7.13, `beta` version 2.8.0.beta11, and `tests-passed` version 2.8.0.beta11 versions of Discourse. There are no workarounds aside from upgrading.","aliases":["CVE-2022-21677","GHSA-768r-ppv4-5r27"],"modified":"2026-09-08T08:45:32.180715543Z","published":"2024-03-06T11:08:07.875Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:2.8.0:beta10:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:2.8.0:beta1:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:2.8.0:beta2:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:2.8.0:beta3:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:2.8.0:beta4:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:2.8.0:beta5:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:2.8.0:beta6:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:2.8.0:beta7:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:2.8.0:beta8:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:2.8.0:beta9:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://github.com/discourse/discourse/commit/fff8b98485561b12d070c0a8c39f4e503813ab44"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-768r-ppv4-5r27"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-21677"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"2.7.12"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2022-21677.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}],"schema_version":"1.9.0"}
