{"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":"2026-08-12T03:51:41.313864352Z","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":"4571b10ee5a3c46249271b2870d6eaf37994460f"},{"fixed":"0876f262e932da2478ed1d2ec275bd2153001213"},{"introduced":"17daf077e2f11def391859f83d294bb71760b1cf"},{"fixed":"1a5a6f66cb821ed29a737311d6fdc2eba5adc915"},{"fixed":"c186a46910431020e8efc425dec2133e7a99fa9a"}],"database_specific":{"cpe":["cpe:2.3:a:discourse:discourse:*:*:*:*:stable:*:*:*","cpe:2.3:a:discourse:discourse:*:*:*:*:beta:*:*:*","cpe:2.3:a:discourse:discourse:3.1.0:beta1:*:*:beta:*:*:*"],"extracted_events":[{"introduced":"0"},{"fixed":"3.0.1"},{"fixed":"3.1.0"},{"introduced":"3.1.0-beta1"},{"last_affected":"3.1.0-beta1"}],"source":["CPE_RANGE","CPE_STRING","REFERENCES"]}}],"versions":["3.1.0-beta1","beta \u003c 3.1.0.beta2","stable \u003c 3.0.1","v3.0.6","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v3.1.0.beta1","v2.8.14","v2.8.13","v2.8.12","v2.8.11","v2.8.10","v2.8.9","v2.8.8","v2.8.7","v2.8.6","v2.8.5","v2.8.4","v2.8.3","v2.8.2","v2.8.1","v2.8.0","v2.7.13","v2.7.12","v2.7.11","v2.7.10","v2.7.9","v2.7.8","v2.7.7","v2.7.6","v2.7.5","v2.7.4","v2.7.3","v2.7.2","v2.7.1","v2.7.0","v2.6.7","v2.6.6","v2.6.5","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.6.0","v2.5.5","v2.5.4","v2.5.3","v2.5.2","v2.5.1","v2.5.0","v2.4.5","v2.4.4","v2.4.3","v2.4.2","v2.4.1","v2.4.0","v2.3.10","v2.3.9","v2.3.8","v2.3.7","v2.3.6","v2.3.5","v2.3.4","v2.3.3","v2.3.2","v2.3.1","v2.3.0","v2.2.6","v2.2.5","v2.2.4","v2.2.3","v2.2.2","v2.2.1","v2.2.0","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v1.9.7","v1.9.6","v1.9.5","v1.9.4","v1.9.3","v1.9.2","v1.9.1","v1.9.0","v1.8.11","v1.8.10","v1.8.9","v1.8.8","v1.8.7","v1.8.6","v1.8.5","v1.8.4","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.10","v1.7.9","v1.7.8","v1.7.7","v1.7.6","v1.7.5","v1.7.4","v1.7.3","v1.7.2","v1.7.1","v1.7.0","v1.6.10","v1.6.9","v1.6.8","v1.6.7","v1.6.6","v1.6.5","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.4","v1.5.3","v1.5.2","v1.5.1","v1.5.0","v1.4.7","v1.4.6","v1.4.5","v1.4.4","v1.4.3","v1.4.2","v1.4.1","v1.4.0","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.4","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v0.9.9.18","v0.9.9.17","v0.9.9.16","v0.9.9.15","v0.9.9.14","v0.9.9.13","v0.9.9.12","v0.9.9.11","v0.9.9.10","v0.9.9.9","v0.9.9.8","v0.9.9.7","v0.9.9.6","v0.9.9.5","v0.9.9.4","v0.9.9.3","v0.9.9.2","v0.9.9.1","v0.9.8.11","v0.9.8.10","v0.9.8.9","v0.9.8.8","v0.9.8.7","v0.9.8.6","v0.9.8.5","v0.9.8.4","v0.9.8.3","v0.9.8.2","v0.9.8.1","v0.9.8","v0.9.7.9","v0.9.7.8","v0.9.7.7","v0.9.7.6","v0.9.7.5","v0.9.7.4","v0.9.7.3","v0.9.7.2","v0.9.7.1","v0.9.7","v0.9.6.4","v0.9.6.3","v0.9.6.1","v0.9.6","v0.9.5.2","v0.9.5.1","v0.9.5","v0.9.4","v0.9.3","v0.9.2.6","v0.9.2.5","v0.9.2","v0.9.1","v0.9.0","v0.8.9","v0.8.8","v0.8.7","v0.8.6","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-25172.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:L/A:N"}]}
