FAQ

According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires an attacker to invest time in repeated exploitation attempts through sending constant or intermittent data. How could an attacker exploit this vulnerability via the Network? An attacker could host a specially crafted website designed to exploit the vulnerability through Microsoft Edge and then convince a user to view the website. However, in all cases an attacker would have no way to force a user to view the attacker-controlled content. Instead, an attacker would have to convince a user to take action, typically by an enticement in an email or instant message, or by getting the user to open an attachment sent through email. What is the version information for this release? Microsoft Edge Version Date Released Based on Chromium Version 135.0.7049.85 4/11/2025 135.0.3179.73
