CVE-2026-5283Network attack vector

Cross-origin data disclosure

Published Apr 1, 2026 · Updated Apr 1, 2026

Information disclosure in ANGLE in Google Chrome before 146.0.7680.178 allows remote attackers to leak cross-origin data via crafted HTML. Google has not disclosed the affected ANGLE code path or the incorrect operation that permits one origin to obtain another origin's data; the linked Chromium issue is access-restricted. Exploitation requires a user to load the crafted page, and the reported consequence is disclosure without integrity or availability impact.
