Authenticated script injection via unencoded upload errors
Published Dec 31, 2022 · Updated Aug 5, 2024
Cross-site scripting in vova07 Yii2 FileAPI Widget 0.1.8 and earlier allows remote authenticated users to inject script via a filename. UploadAction::run returns the model's first file-validation error without HTML encoding, allowing filename content preserved in that error to reach the response. An account able to submit a crafted upload must induce a validation error and persuade another user to render the returned message, enabling script execution in that user's browser.
