The flaw stems from improper deallocation of form objects, and an attacker can leverage it by presenting a malicious webpage. The impact is the ability to run code with the privileges of the browser process, potentially leading to privilege escalation or data theft. This weakness is classified as CWE\u2011416.", "risk_and_exploitability": "The vulnerability has a CVSS score of 8.8, indicating high severity. EPSS data is not available, and the issue is not listed in the CISA KEV catalog, but the lack of a publicly available exploit does not diminish the threat. The attack vector is inferred to be a crafted HTML page that a user needs to view, implying a reliance on user interaction; however, once loaded, the attacker can execute code within the browser\u2019s sandbox. The combination of a high\u2011severity flaw and the need for user action suggests a moderate to high exploitation likelihood in environments where users regularly visit untrusted sites or download HTML files. The risk escalates if system administrators do not promptly resolve the vulnerability."}}}}, "created": "2026-04-15T21:30:13.804636+00:00", "title": "Use\u2011After\u2011Free in Chrome Forms Enables Remote Code Execution", "updated": "2026-04-15T22:00:06.620595+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
