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." } ], "metrics": { "cvssMetricV31": [ { "source": "security-advisories@github.com", "type": "Secondary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:L/A:N", "baseScore": 4.4, "baseSeverity": "MEDIUM", "attackVector": "NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "LOW", "userInteraction": "REQUIRED", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "availabilityImpact": "NONE" }, "exploitabilityScore": 1.3, "impactScore": 2.7 }, { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N", "baseScore": 5.4, "baseSeverity": "MEDIUM", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "REQUIRED", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "availabilityImpact": "NONE" }, "exploitabilityScore": 2.3, "impactScore": 2.7 } ] }, "weaknesses": [ { "source": "security-advisories@github.com", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-79" } ] } ], "configurations": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:a:discourse:discourse:*:*:*:*:stable:*:*:*", "versionEndExcluding": "3.0.1", "matchCriteriaId": "C19D7945-EB52-43C0-B9B7-8C250FEDC451" }, { "vulnerable": true, "criteria": "cpe:2.3:a:discourse:discourse:*:*:*:*:beta:*:*:*", "versionEndExcluding": "3.1.0", "matchCriteriaId": "D3C08972-822D-4657-9B6F-02BC692B7C6E" }, { "vulnerable": true, "criteria": "cpe:2.3:a:discourse:discourse:3.1.0:beta1:*:*:beta:*:*:*", "matchCriteriaId": "B9BBED17-A6BA-4F17-8814-8D8521F28375" } ] } ] } ], "references": [ { "url": "https://github.com/discourse/discourse/commit/1a5a6f66cb821ed29a737311d6fdc2eba5adc915", "source": "security-advisories@github.com", "tags": [ "Patch" ] }, { "url": "https://github.com/discourse/discourse/commit/c186a46910431020e8efc425dec2133e7a99fa9a", "source": "security-advisories@github.com", "tags": [ "Patch" ] }, { "url": "https://github.com/discourse/discourse/pull/20008", "source": "security-advisories@github.com", "tags": [ "Patch" ] }, { "url": "https://github.com/discourse/discourse/pull/20009", "source": "security-advisories@github.com", "tags": [ "Patch" ] }, { "url": "https://github.com/discourse/discourse/security/advisories/GHSA-7pm2-prxw-wrvp", "source": "security-advisories@github.com", "tags": [ "Vendor Advisory" ] }, { "url": "https://github.com/discourse/discourse/commit/1a5a6f66cb821ed29a737311d6fdc2eba5adc915", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Patch" ] }, { "url": "https://github.com/discourse/discourse/commit/c186a46910431020e8efc425dec2133e7a99fa9a", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Patch" ] }, { "url": "https://github.com/discourse/discourse/pull/20008", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Patch" ] }, { "url": "https://github.com/discourse/discourse/pull/20009", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Patch" ] }, { "url": "https://github.com/discourse/discourse/security/advisories/GHSA-7pm2-prxw-wrvp", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Vendor Advisory" ] } ] }
