{"id":"CVE-2023-25172","summary":"Discourse vulnerable to Cross-site Scripting - user name displayed on post","details":"Discourse is an open-source discussion platform. Prior to version 3.0.1 of the `stable` branch and version 3.1.0.beta2 of the `beta` and `tests-passed` branches, a maliciously crafted URL can be included in a user's full name field to to carry out cross-site scripting attacks on sites with a disabled or overly permissive CSP (Content Security Policy). Discourse's default CSP prevents this vulnerability. The vulnerability is patched in version 3.0.1 of the `stable` branch and version 3.1.0.beta2 of the `beta` and `tests-passed` branches. As a workaround, enable and/or restore your site's CSP to the default one provided with Discourse.","aliases":["BIT-discourse-2023-25172","GHSA-7pm2-prxw-wrvp"],"modified":"2026-04-10T04:55:59.548368Z","published":"2023-03-17T16:07:27.668Z","database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/25xxx/CVE-2023-25172.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/25xxx/CVE-2023-25172.json"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-7pm2-prxw-wrvp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-25172"},{"type":"FIX","url":"https://github.com/discourse/discourse/commit/1a5a6f66cb821ed29a737311d6fdc2eba5adc915"},{"type":"FIX","url":"https://github.com/discourse/discourse/commit/c186a46910431020e8efc425dec2133e7a99fa9a"},{"type":"FIX","url":"https://github.com/discourse/discourse/pull/20008"},{"type":"FIX","url":"https://github.com/discourse/discourse/pull/20009"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/discourse/discourse","events":[{"introduced":"0"},{"fixed":"c186a46910431020e8efc425dec2133e7a99fa9a"}]}],"versions":["v0.8.0","v0.8.1","v0.8.2","v0.8.3","v0.8.4","v0.8.5","v0.8.6","v0.8.7","v0.8.8","v0.8.9","v0.9.0","v0.9.1","v0.9.2","v0.9.2.5","v0.9.2.6","v0.9.3","v0.9.4","v0.9.5","v0.9.5.1","v0.9.5.2","v0.9.6","v0.9.6.1","v0.9.6.3","v0.9.6.4","v0.9.7","v0.9.7.1","v0.9.7.2","v0.9.7.3","v0.9.7.4","v0.9.7.5","v0.9.7.6","v0.9.7.7","v0.9.7.8","v0.9.7.9","v0.9.8","v0.9.8.1","v0.9.8.10","v0.9.8.11","v0.9.8.2","v0.9.8.3","v0.9.8.4","v0.9.8.5","v0.9.8.6","v0.9.8.7","v0.9.8.8","v0.9.8.9","v0.9.9.1","v0.9.9.10","v0.9.9.11","v0.9.9.12","v0.9.9.13","v0.9.9.14","v0.9.9.15","v0.9.9.16","v0.9.9.17","v0.9.9.18","v0.9.9.2","v0.9.9.3","v0.9.9.4","v0.9.9.5","v0.9.9.6","v0.9.9.7","v0.9.9.8","v0.9.9.9","v1.0.0","v1.1.0.beta2","v1.1.0.beta3","v1.1.0.beta4","v1.1.0.beta5","v1.1.0.beta6","v1.1.0.beta6b","v1.1.0.beta7","v1.1.0.beta8","v1.2.0.beta1","v1.2.0.beta2","v1.2.0.beta3","v1.2.0.beta4","v1.2.0.beta5","v1.2.0.beta6","v1.2.0.beta7","v1.2.0.beta8","v1.2.0.beta9","v1.3.0.beta1","v1.3.0.beta10","v1.3.0.beta11","v1.3.0.beta2","v1.3.0.beta3","v1.3.0.beta4","v1.3.0.beta5","v1.3.0.beta6","v1.3.0.beta9","v1.4.0.beta1","v1.4.0.beta10","v1.4.0.beta11","v1.4.0.beta12","v1.4.0.beta2","v1.4.0.beta3","v1.4.0.beta4","v1.4.0.beta5","v1.4.0.beta6","v1.4.0.beta7","v1.4.0.beta8","v1.4.0.beta9","v1.5.0.beta1","v1.5.0.beta10","v1.5.0.beta11","v1.5.0.beta12","v1.5.0.beta13","v1.5.0.beta13b","v1.5.0.beta14","v1.5.0.beta2","v1.5.0.beta4","v1.5.0.beta5","v1.5.0.beta6","v1.5.0.beta7","v1.5.0.beta8","v1.5.0.beta9","v1.6.0.beta1","v1.6.0.beta10","v1.6.0.beta11","v1.6.0.beta12","v1.6.0.beta2","v1.6.0.beta3","v1.6.0.beta4","v1.6.0.beta5","v1.6.0.beta6","v1.6.0.beta7","v1.6.0.beta8","v1.6.0.beta9","v1.7.0.beta1","v1.7.0.beta10","v1.7.0.beta11","v1.7.0.beta2","v1.7.0.beta3","v1.7.0.beta4","v1.7.0.beta5","v1.7.0.beta6","v1.7.0.beta7","v1.7.0.beta8","v1.7.0.beta9","v1.8.0.beta1","v1.8.0.beta10","v1.8.0.beta11","v1.8.0.beta12","v1.8.0.beta13","v1.8.0.beta2","v1.8.0.beta3","v1.8.0.beta4","v1.8.0.beta5","v1.8.0.beta6","v1.8.0.beta7","v1.8.0.beta8","v1.8.0.beta9","v1.9.0.beta1","v1.9.0.beta10","v1.9.0.beta11","v1.9.0.beta12","v1.9.0.beta13","v1.9.0.beta14","v1.9.0.beta15","v1.9.0.beta16","v1.9.0.beta17","v1.9.0.beta2","v1.9.0.beta3","v1.9.0.beta4","v1.9.0.beta5","v1.9.0.beta6","v1.9.0.beta7","v1.9.0.beta8","v1.9.0.beta9","v2.0.0.beta1","v2.0.0.beta10","v2.0.0.beta2","v2.0.0.beta3","v2.0.0.beta4","v2.0.0.beta5","v2.0.0.beta6","v2.0.0.beta7","v2.0.0.beta8","v2.0.0.beta9","v2.1.0.beta1","v2.1.0.beta2","v2.1.0.beta3","v2.1.0.beta4","v2.1.0.beta5","v2.1.0.beta6","v2.2.0.beta1","v2.2.0.beta10","v2.2.0.beta2","v2.2.0.beta3","v2.2.0.beta4","v2.2.0.beta5","v2.2.0.beta6","v2.2.0.beta7","v2.2.0.beta8","v2.2.0.beta9","v2.3.0.beta1","v2.3.0.beta10","v2.3.0.beta11","v2.3.0.beta2","v2.3.0.beta3","v2.3.0.beta4","v2.3.0.beta5","v2.3.0.beta6","v2.3.0.beta7","v2.3.0.beta8","v2.3.0.beta9","v2.4.0.beta1","v2.4.0.beta10","v2.4.0.beta11","v2.4.0.beta2","v2.4.0.beta3","v2.4.0.beta4","v2.4.0.beta5","v2.4.0.beta6","v2.4.0.beta7","v2.4.0.beta8","v2.4.0.beta9","v2.5.0.beta1","v2.5.0.beta2","v2.5.0.beta3","v2.5.0.beta4","v2.5.0.beta5","v2.5.0.beta6","v2.5.0.beta7","v2.6.0.beta1","v2.6.0.beta2","v2.6.0.beta3","v2.6.0.beta4","v2.6.0.beta5","v2.6.0.beta6","v2.7.0.beta1","v2.7.0.beta2","v2.7.0.beta3","v2.7.0.beta4","v2.7.0.beta5","v2.7.0.beta6","v2.7.0.beta7","v2.7.0.beta8","v2.7.0.beta9","v2.8.0.beta1","v2.8.0.beta10","v2.8.0.beta11","v2.8.0.beta2","v2.8.0.beta3","v2.8.0.beta4","v2.8.0.beta5","v2.8.0.beta6","v2.8.0.beta7","v2.8.0.beta8","v2.8.0.beta9","v2.9.0.beta1","v2.9.0.beta10","v2.9.0.beta11","v2.9.0.beta12","v2.9.0.beta13","v2.9.0.beta14","v2.9.0.beta2","v2.9.0.beta3","v2.9.0.beta4","v2.9.0.beta5","v2.9.0.beta6","v2.9.0.beta7","v2.9.0.beta8","v2.9.0.beta9","v3.0.0.beta15","v3.0.0.beta16","v3.1.0.beta1"],"database_specific":{"source":"h
