The EPSS score is below 1%, showing a low probability of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires a remote attacker to craft a malicious page and convince a user to interact with certain UI gestures; it is a user\u2011interaction\u2011dependent attack rather than a purely remote exploit. If successfully performed, it permits execution of arbitrary scripts in the user\u2019s browser context, potentially leading to sensitive data exposure or unauthorized actions performed on behalf of the user."}}}}, "created": "2026-04-09T08:16:53.543095+00:00", "updated": "2026-04-14T16:37:30.385549+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
