The weakness is formally classified as CWE\u2011125, buffer over-read.", "risk_and_exploitability": "The issue carries a medium severity designation by Chromium because the attacker must be able to run an HTML page in the user\u2019s browser. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog, suggesting limited public exploitation.
