{"cve":"CVE-2023-46130","nvd":{"published":"2023-11-10T15:15:08.870","modified":"2026-06-17T06:30:12.863","status":"Modified","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","score":5.4},"cwes":["CWE-770"],"references":["https://github.com/discourse/discourse/commit/6183d9633de873ac2b1e9cdb6ac1c94b4ffae9cb","https://github.com/discourse/discourse/commit/89a2e60706ce22e4afc463d03af2f34c53291800","https://github.com/discourse/discourse/security/advisories/GHSA-c876-638r-vfcg","https://github.com/discourse/discourse/commit/6183d9633de873ac2b1e9cdb6ac1c94b4ffae9cb","https://github.com/discourse/discourse/commit/89a2e60706ce22e4afc463d03af2f34c53291800"],"products":["discourse:discourse"],"source":"nvd","synced_at":"2026-10-19T21:42:07.670898610+00:00"},"epss":{"cve":"CVE-2023-46130","score":0.00702,"percentile":0.53264,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
