Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 fails to strip EXIF metadata including GPS geolocation data from uploaded images, allowing information disclosure. Attackers can download uploaded images and extract precise latitude and longitude coordinates revealing user physical location at capture time.
AnalysisAI
Capgo before version 12.128.2 exposes user physical location by retaining EXIF GPS metadata in uploaded images without sanitization. Unauthenticated remote attackers can download images hosted on affected Capgo instances and extract embedded latitude/longitude coordinates, revealing where users were physically located at the time of photo capture. No public exploit is identified at time of analysis, and a vendor patch is available in version 12.128.2.
Technical ContextAI
EXIF (Exchangeable Image File Format) is a metadata standard embedded in image files - particularly JPEG and TIFF - by cameras and smartphones. Modern mobile devices routinely embed GPS coordinates, timestamps, and device identifiers in this metadata by default. The root cause class is CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor): the image upload pipeline in Capgo (cpe:2.3:a:capgo:capgo:*:*:*:*:*:*:*:*) lacks a sanitization or stripping step to remove EXIF data before storing or serving uploaded content. Capgo is an open-source mobile backend platform (BaaS) built for Capacitor-based apps. Because the platform does not sanitize at ingest, any image uploaded with GPS tagging active on the source device retains full geolocation precision for the lifetime of that asset in the system.
RemediationAI
The primary fix is to upgrade Capgo to version 12.128.2 or later, which introduces EXIF metadata stripping during image upload processing per the vendor advisory at https://github.com/Cap-go/capgo/security/advisories/GHSA-c5w9-886p-9j2x. For deployments that cannot immediately upgrade, compensating controls include: (1) configuring a reverse proxy or CDN layer (e.g., Cloudflare Images, imgproxy) to strip EXIF metadata from images at the egress point before serving - this prevents new exposure but does not remediate already-stored images; (2) running a one-time retroactive stripping job using a tool such as ExifTool or libvips on all previously uploaded images in storage; (3) advising end users to disable GPS tagging in their device camera settings, though this reduces functionality and places the burden on users rather than the platform. Note that the patch in 12.128.2 is confirmed available per vendor advisory; no exact patch version ambiguity exists.
