Memory disclosure via Autofill use-after-free
Published Jun 11, 2026 · Updated Jun 11, 2026
Use after free in Autofill in Google Chrome before 149.0.7827.115 allows remote attackers to read process memory via crafted HTML. Google has not disclosed the affected Autofill object, the lifetime error that leaves freed memory reachable, or the triggering HTML structure. Exploitation requires user interaction and a compromised renderer; the reported consequence is disclosure of process-memory contents.
