{"id":"BIT-discourse-2026-27162","summary":"DIscourse doesn't prevent whispers to leak in excerpts","details":"Discourse is an open source discussion platform. Prior to versions 2025.12.2, 2026.1.1, and 2026.2.0, `posts_nearby` was checking topic access but then returning all posts regardless of type, including whispers that should only be visible to whisperers. Use `Post.secured(guardian)` to properly filter post types based on user permissions. Versions 2025.12.2, 2026.1.1, and 2026.2.0 patch the issue. No known workarounds are available.","aliases":["CVE-2026-27162","GHSA-gffm-43j4-372w"],"modified":"2026-09-08T08:46:21.489878928Z","published":"2026-03-03T13:29:27.139Z","database_specific":{"cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-gffm-43j4-372w"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27162"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2025.12.2"},{"introduced":"2026.1.0"},{"fixed":"2026.1.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2026-27162.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
