From 6.0.0 until 6.8.14 and 7.0.37, the src/app/Library/Uploaders/SingleBase64Image.php methods SingleBase64Image::uploadFiles and SingleBase64Image::uploadRepeatableFiles, used by image fields through withFiles(), accept any data URI beginning with data:image without validating the declared MIME subtype or decoded bytes, while src/app/Library/Uploaders/Support/FileNameGenerator.php method FileNameGenerator::getExtensionFromFile applies mime_content_type() to the data URI instead of the decoded content. An authenticated administrator can therefore store arbitrary file content under an extensionless filename on the configured disk, which can cause stored cross-site scripting or other unintended behavior when the file is served and accessed. This issue is fixed in version 7.0.38 and 6.8.14.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-54179)\n\nAffected packages:\n\n- `backpack/crud >= 6.0.0, < 6.8.14`\n- `backpack/crud >= 7.0.0, < 7.0.38`\n\nPatched in:\n\n- `backpack/crud 6.8.14`\n- `backpack/crud 7.0.38`\n\nSource: https://github.com/advisories/GHSA-8hw4-7qjr-3wxg","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":24.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
