{"id":"BIT-discourse-2025-48062","summary":"Discourse vulnerable to HTML injection when inviting to topic via email","details":"Discourse is an open-source discussion platform. Prior to version 3.4.4 of the `stable` branch, version 3.5.0.beta5 of the `beta` branch, and version 3.5.0.beta6-dev of the `tests-passed` branch, certain invites via email may result in HTML injection in the email body if the topic title includes HTML. This includes inviting someone (without an account) to a PM and inviting someone (without an account) to a topic with a custom message. This issue is patched in version 3.4.4 of the `stable` branch, version 3.5.0.beta5 of the `beta` branch, and version 3.5.0.beta6-dev of the `tests-passed` branch. This can be worked around if the relevant templates are overridden without `{topic_title}`.","aliases":["CVE-2025-48062","GHSA-x8mp-chx3-6x2p"],"modified":"2026-09-10T16:00:32.939311910Z","published":"2025-06-11T11:45:04.167Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-x8mp-chx3-6x2p"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-48062"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.4.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2025-48062.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"}
