CVE-2026-19155
Description
A flaw was found in Chromium. This use-after-free vulnerability in the Payments component could allow a remote attacker, who has already compromised the renderer process, to potentially escape the browser's security sandbox. This could be achieved by enticing a user to visit a specially crafted HTML page.
Statement
This Important flaw in Chromium's Payments component allows a remote attacker to potentially escape the browser's sandbox after compromising the renderer process. This elevated impact stems from the ability to bypass security boundaries, which could lead to further system compromise, even though it requires a prior successful exploit of the renderer.
Mitigation
To reduce the risk of exploitation, users should avoid visiting untrusted or suspicious websites. Additionally, employing browser sandboxing mechanisms can help contain potential compromises.
