The Cybernews research team says it’s uncovered a data leak involving Fitify, a popular iOS fitness app with over 25 million installs globally.
According to the report, researchers discovered that 373,000 sensitive user files — including 138,000 progress photos — were stored in a publicly accessible Google Cloud bucket — with no password protection or encryption at rest, meaning anyone could access them.
Cybernews says that among the leaked files were:
- 206,000 user profile photos
- 138,000 progress pictures uploaded by users to track fitness changes
- 13,000 AI coach message attachments, which may include images or text
- 6,000 body scan files, including photos and AI-generated metadata (e.g., lean mass, body fat, posture)
Cybernews says that its research highlights include:
- Many of the exposed photos were semi-nude body scans, captured by users trying to document weight loss or muscle growth.
- Fitify promises encryption in transit, but the lack of basic access controls poses serious privacy risks.
- Researchers also found hardcoded secrets embedded in the app’s code — including Google API and Client IDs, Firebase database URLs, Facebook tokens, and even an Algolia API key, which wasn’t disclosed in the privacy policy.
- These exposed credentials could let attackers access backend infrastructure, impersonate users, or inject malicious content.
