{"id":"BIT-discourse-2026-72731","summary":"Discourse: Strip SQL comments and use non-recursive parameter interpolation in Data Explorer","details":"Discourse is an open-source discussion platform. From 2026.1.0 until 2026.1.7, 2026.6.2, 2026.7.1, and 2026.8.0, anyone able to run a parameterized Data Explorer query, including non-staff members of a group a query is shared with, could craft parameter values that escaped the intended query and executed arbitrary SQL through plugins/discourse-data-explorer/lib/discourse_data_explorer/data_explorer.rb and plugins/discourse-data-explorer/lib/discourse_data_explorer/workflows/sql_action/v1.rb. Recursive parameter interpolation allowed one parameter value to introduce another parameter, and parameter declarations in SQL comments could be used to inject a statement. Queries run in a read-only transaction, so data could not be modified, but any table could be read. This issue is fixed in versions 2026.1.7, 2026.6.2, 2026.7.1, and 2026.8.0.","aliases":["CVE-2026-72731","GHSA-wm63-83xp-59r5"],"modified":"2026-08-17T08:10:36.591616864Z","published":"2026-08-17T05:44:38.149Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://github.com/discourse/discourse/commit/2bdab888cef561348470dee204a4879d83fbb5c3"},{"type":"WEB","url":"https://github.com/discourse/discourse/commit/3dc7f0da7aa18548281152e285244efb1cc8ad0d"},{"type":"WEB","url":"https://github.com/discourse/discourse/commit/674ba6fc64184fd7d8e21183c5d8cb22367faa6e"},{"type":"WEB","url":"https://github.com/discourse/discourse/commit/ce9ccf24ec3538172dc8f8199728e08f63e57693"},{"type":"WEB","url":"https://github.com/discourse/discourse/security/advisories/GHSA-wm63-83xp-59r5"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72731"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.1.7"},{"introduced":"2026.6.0"},{"fixed":"2026.6.2"},{"introduced":"2026.7.0"},{"fixed":"2026.7.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2026-72731.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N"}]}],"schema_version":"1.9.0"}
