Improper authorization in Microsoft Edge (Chromium-based) allows an unauthorized attacker to execute code over a network.
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 craft deceptive or invisible form elements and user to perform two sequential taps. According to the CVSS metric, the attack vector is network (AV:N) and user interaction is required (UI:R). What is the target context of the remote code execution? This attack requires a user to open a specially crafted file from the attacker to 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. According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability? An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities. According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do? The user must visit the attacker‑controlled webpage, and perform the two tap gestures that cause autofill to activate. What is the version information for this release? Microsoft Edge Version Date Released Based on Chromium Version 150.0.4078.48 07/03/2026 150.0.7871.47
