Privilege escalation via Reading List input validation
Published Jun 4, 2026 · Updated Jun 4, 2026
Improper input validation in Chrome for iOS before 149.0.7827.53 allows remote attackers to escalate privileges through crafted HTML. Google identifies Reading List as the affected component but has not published the untrusted field, validation failure, or privileged operation. Exploitation requires a user to open attacker-controlled content and perform specific UI gestures; the public record does not define the resulting privilege boundary.
