Arbitrary file overwrite via imported path traversal
Published Mar 31, 2026 · Updated Mar 31, 2026
Path traversal in DeftPDF Document Translator 54.0 allows attackers to overwrite internal app files through the file import process. SplashScreenActivity accepts an imported file's attacker-controlled name and content without blocking traversal outside the intended destination, allowing writes into internal storage. A malicious Android app can trigger the import after it is opened, causing a crash, sensitive-data exposure, or code execution if a critical file is replaced.
