CVE-2023-4860Network attack vector

Sandbox escape via undisclosed Skia implementation flaw

Published Jul 16, 2024 · Updated Aug 2, 2024

Sandbox escape in Skia in Google Chrome before 115.0.5790.98 allows remote attackers to escape a compromised renderer via crafted HTML. Google identifies the locus only as an inappropriate Skia implementation; the restricted issue does not publicly disclose the faulty operation on untrusted input. Exploitation requires both user interaction with attacker-controlled HTML and an already-compromised renderer, after which code can cross the browser sandbox boundary.
