The flaw originates from insufficient validation of untrusted input, classified as CWE\u201120. Exploiting this bug can grant the attacker privileges beyond the renderer, potentially enabling arbitrary code execution on the user\u2019s machine.", "risk_and_exploitability": "Chromium labels the vulnerability as high severity, but no EPSS score is available and it is not listed in the CISA KEV catalog. The attack requires a remote attacker to already have leveraged a compromise of the renderer process, after which a crafted HTML file triggers the validation flaw and facilitates a sandbox escape. While the immediate exploitation probability is unclear, the potential for privilege escalation and arbitrary code execution warrants prompt attention."}}}}, "created": "2026-04-29T00:30:15.864810+00:00", "title": "Chrome Feedback Feature Enables Rendering Process Sandbox Escape", "updated": "2026-04-29T02:15:47.408824+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
