CVE-2026-5452Public exploit

Local Uploadcare key disclosure via BuildConfig embedding

Published Apr 3, 2026 · Updated Apr 3, 2026

Hard-coded cryptographic key use in UCC CampusConnect 14.3.0 through 14.3.5 for Android allows local users to read an Uploadcare private key. The campusconnect.ucc BuildConfig.java file embeds the key in the application package, making it recoverable through local APK inspection rather than protected key storage. Access to the app package and low local privileges are required; the public proof of concept concerns key exposure, while the record documents only confidentiality impact and does not substantiate remote code execution.
