CVE-2023-1974Network attack vector

Sensitive image metadata disclosure via unstripped EXIF

Published Apr 11, 2023 · Updated Feb 7, 2025

Metadata exposure in Apache Answer before 1.0.8 allows remote attackers to read EXIF data and GPS coordinates from uploaded images. The uploadFile path stores user-supplied images without removing embedded EXIF metadata; the patch adds Dexif to rewrite each upload without that data. Exposure requires a user to upload an image containing sensitive metadata, after which remote attackers who can retrieve it can read the embedded details.
