Prior to 8.6.73 and 9.7.1-alpha.4, a file can be uploaded with a filename extension that passes the file extension allowlist (e.g., .txt) but with a Content-Type header that differs from the extension (e.g., text/html). The Content-Type is passed to the storage adapter without consistency validation. Storage adapters that store and serve the provided Content-Type (such as S3 or GCS) serve the file with the mismatched Content-Type. The default GridFS adapter is not affected because it derives Content-Type from the filename at serving time. This vulnerability is fixed in 8.6.73 and 9.7.1-alpha.4."}], "lastModified": "2026-04-07T18:01:08.000", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "F448C862-A7B1-4475-85E1-48755F259577", "versionEndExcluding": "8.6.73"}, {"criteria": "cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "EF03C109-6DCF-4359-A9EC-44C14A80B9FA", "versionEndExcluding": "9.7.1", "versionStartIncluding": "9.0.0"}, {"criteria": "cpe:2.3:a:parseplatform:parse-server:9.7.1:alpha1:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "4F96BFE1-E9D0-4D78-BD1A-1AE1259F3FF9"}, {"criteria": "cpe:2.3:a:parseplatform:parse-server:9.7.1:alpha2:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "C80914A3-E910-4C75-A542-768711DF429D"}, {"criteria": "cpe:2.3:a:parseplatform:parse-server:9.7.1:alpha3:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "88D6D996-366F-4683-A60A-ADFAD1909EBD"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
