## Technical details

The ShareActivity component in BlueLM Copilot fails to properly validate file paths in ACTION_SEND intents, allowing an attacker to use ".." sequences in ContentProvider-supplied file names to traverse directories and write files outside the intended location. Attack requires a malicious application to be installed locally on the device; no network or user interaction is needed. An attacker gains the ability to write arbitrary files, potentially compromising system integrity or installing malware.
