CVE-2026-79070Network attack vector

Cross-origin data disclosure via cache reference misresolution

Published Aug 25, 2026 · Updated Aug 25, 2026

Incorrect reference resolution in Google Chrome before 152.0.7977.65 allows remote attackers to read cross-origin data via crafted HTML. Chrome's public advisory identifies the Cache component but does not disclose which reference is resolved incorrectly or how the origin check is bypassed. A user must open the attacker's page; the documented consequence is limited to cross-origin data disclosure, with no integrity or availability impact.
