FacturaScripts: Unstripped Image Metadata (EXIF) Leakage via Library Module File Upload/Download
FacturaScripts is an open source accounting and invoicing software. In versions prior to 2026, the Library module stores and serves uploaded images byte-for-byte, without stripping EXIF/XMP/IPTC metadata. Any authenticated user who downloaded an image could extract the uploader's embedded metadata, which included GPS coordinates, device information, timestamps, embedded comments/notes, thumbnail previews, and other personally identifiable information (PII) preserved in the image metadata. Of all FacturaScripts' image upload features, only the Library module combined unrestricted uploads, persistent storage, authenticated download access, and a total lack of server-side metadata sanitization. This vulnerability carries significant real-world impact: an employee uploading a photo taken at their home inadvertently discloses their precise home address to every user with Library download access. This issue has been fixed in version 2026.
