CVE-2025-69621Public exploitNetwork attack vector

Arbitrary file overwrite via imported filename traversal

Published Feb 4, 2026 · Updated Feb 4, 2026

Path traversal in Comic Book Reader 1.0.95 allows context-dependent attackers to overwrite files in the app's internal storage. MainActivity copies content from an ACTION_VIEW URI while using provider-controlled display-name metadata as a destination path without traversal validation. A victim must open a malicious Android app; its crafted content provider can corrupt configuration, stop launches, expose data, or enable code execution.
