Cross-origin data disclosure via Skia input validation
Published Jun 4, 2026 · Updated Jun 4, 2026
Improper input validation in Skia in Google Chrome before 149.0.7827.53 allows remote attackers to leak cross-origin data. Skia accepts untrusted input from a crafted HTML page without sufficient validation, but Google has not publicly disclosed the affected function or exact validation failure. Exploitation requires a renderer process compromise and user interaction with the crafted page; the reported consequence is data disclosure, not modification or service interruption.
