{"id":"BIT-discourse-2023-46130","summary":"Bypassing height value allowed in some theme components","details":"Discourse is an open source platform for community discussion. Prior to version 3.1.3 of the `stable` branch and version 3.2.0.beta3 of the `beta` and `tests-passed` branches, some theme components allow users to add svgs with unlimited `height` attributes, and this can affect the availability of subsequent replies in a topic. Most Discourse instances are unaffected, only instances with the svgbob or the mermaid theme component are within scope. The issue is patched in version 3.1.3 of the `stable` branch and version 3.2.0.beta3 of the `beta` and `tests-passed` branches. As a workaround, disable or remove the relevant theme components.","aliases":["CVE-2023-46130","GHSA-c876-638r-vfcg"],"modified":"2026-09-08T08:46:14.754848665Z","published":"2024-03-06T10:52:27.869Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:stable:*:*:*","cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:*:*:*:*:beta:*:*:*","cpe:2.3:a:discourse:discourse:3.2.0:beta1:*:*:beta:*:*:*","cpe:2.3:a:discourse:discourse:3.2.0:beta2:*:*:beta:*:*:*"]},"references":[{"type":"FIX","url":"https://github.com/discourse/discourse/commit/6183d9633de873ac2b1e9cdb6ac1c94b4ffae9cb"},{"type":"FIX","url":"https://github.com/discourse/discourse/commit/89a2e60706ce22e4afc463d03af2f34c53291800"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-c876-638r-vfcg"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-46130"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.2.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2023-46130.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L"}]}],"schema_version":"1.9.0"}
