Local sandbox escape via malicious file
Published Jun 30, 2026 · Updated Jun 30, 2026
Improper input validation in Google Chrome Chromoting before 150.0.7871.47 allows local users to escape the Windows sandbox via a malicious file. Chromoting processes attacker-controlled file content without sufficient validation; Google has not disclosed the specific parser, field, or failed check because the issue remains restricted. Exploitation requires local access and user interaction; success crosses the browser sandbox boundary but does not by itself establish system-level privilege.
