In affected versions an attacker could upload a malicious piece of media to the media repo, which would then be served with `Content-Disposition: inline` upon download. This vulnerability could be leveraged to execute scripts embedded in SVG content. Commits `77ec235` and `bf8abdd` fix the issue and are included in the 1.3.0 release. Operators should upgrade to v1.3.0 as soon as possible. Operators unable to upgrade should override the `Content-Disposition` header returned by matrix-media-repo as a workaround." } ], "metrics": { "cvssMetricV31": [ { "source": "security-advisories@github.com", "type": "Secondary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:N/A:N", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "REQUIRED", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "NONE", "availabilityImpact": "NONE", "baseScore": 4.1, "baseSeverity": "MEDIUM" }, "exploitabilityScore": 2.3, "impactScore": 1.4 } ] }, "weaknesses": [ { "source": "security-advisories@github.com", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-79" } ] } ], "references": [ { "url": "https://developer.mozilla.org/en-US/docs/Web/SVG/Element/script", "source": "security-advisories@github.com" }, { "url": "https://github.com/turt2live/matrix-media-repo/commit/77ec2354e8f46d5ef149d1dcaf25f51c04149137", "source": "security-advisories@github.com" }, { "url": "https://github.com/turt2live/matrix-media-repo/commit/bf8abdd7a5371118e280c65a8e0ec2b2e9bdaf59", "source": "security-advisories@github.com" }, { "url": "https://github.com/turt2live/matrix-media-repo/security/advisories/GHSA-5crw-6j7v-xc72", "source": "security-advisories@github.com" } ] }
