{"id":"BIT-discourse-2026-33355","summary":"Discourse filters whisper posts from private-posts feed","details":"Discourse is an open-source discussion platform. Prior to versions 2026.3.0, 2026.2.1, and 2026.1.2, the `/private-posts` endpoint did not apply post-type visibility filtering, allowing regular PM participants to see whisper posts in PM topics they had access to. Versions 2026.3.0, 2026.2.1, and 2026.1.2 contain a patch. No known workarounds are available.","aliases":["CVE-2026-33355","GHSA-g4v5-6gfp-3hjq"],"modified":"2026-09-08T08:46:21.656735184Z","published":"2026-03-27T07:10:48.005Z","database_specific":{"cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"FIX","url":"https://github.com/discourse/discourse/commit/84e5865a279716c6866e8c0648d1d8b42320603c"},{"type":"FIX","url":"https://github.com/discourse/discourse/commit/d25b8ee9ee182dbb34e92b34e39878ce4d59bcdc"},{"type":"FIX","url":"https://github.com/discourse/discourse/commit/d2f317271ad7638f1e2791905472ebd9370946d1"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-g4v5-6gfp-3hjq"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33355"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2026.1.0"},{"fixed":"2026.1.2"},{"introduced":"2026.2.0"},{"fixed":"2026.2.1"},{"introduced":"2026.3.0"},{"fixed":"2026.3.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2026-33355.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
