FAQ

According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution? This attack requires an authenticated client to click a link so that an unauthenticated attacker can initiate remote code execution. 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 138.0.3351.65 7/01/2025 138.0.7204.96/.97
