{"id":"BIT-discourse-2026-91133","summary":"Discourse: Escape LIKE metacharacters in upload paths to prevent disclosure","details":"Discourse is an open-source discussion platform. Prior to 2026.1.8, 2026.6.3, 2026.7.2, and 2026.8.0, authenticated users could supply unescaped SQL LIKE metacharacters to upload-resolution patterns, causing wildcard input to select unrelated upload records instead of matching a literal identifier. The affected upload metadata, URL-lookup, and cooked-video-placeholder paths could resolve uploads the user was not authorized to access. This allowed disclosure of restricted metadata, including original filenames and secure-upload paths, without modifying the upload records. This issue is fixed in versions 2026.1.8, 2026.6.3, 2026.7.2, and 2026.8.0.","aliases":["CVE-2026-91133","GHSA-8hxh-573g-52gx"],"modified":"2026-10-01T10:11:02.080880296Z","published":"2026-10-01T09:29:33.589Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:stable:*:*:*","cpe:2.3:a:discourse:discourse:*:*:*:*:beta:*:*:*"]},"references":[{"type":"WEB","url":"https://github.com/discourse/discourse/commit/113c34d433d564bc69642649d501251a7e820b52"},{"type":"WEB","url":"https://github.com/discourse/discourse/commit/20c48bef712ee3edd4f7af58ca1123cb0c16ef6f"},{"type":"WEB","url":"https://github.com/discourse/discourse/commit/a04cab107a9f57939456181c4b082d0a34ec39bd"},{"type":"WEB","url":"https://github.com/discourse/discourse/commit/cb3ca8420fcc7aba334effd011cf41943a336fa6"},{"type":"WEB","url":"https://github.com/discourse/discourse/pull/42882"},{"type":"WEB","url":"https://github.com/discourse/discourse/security/advisories/GHSA-8hxh-573g-52gx"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-91133"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.8.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2026-91133.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"}
