Impact & technical details
Security Feature Bypass
What kind of security feature could be bypassed by successfully exploiting this vulnerability? An attacker who successfully exploited this vulnerability could smuggle another HTTP request and bypass front-end security controls or hijack other users' credentials.
According to the CVSS metrics, successful exploitation of this vulnerability could lead to no loss of confidentiality (C:N) and integrity (I:N), but could lead to some loss of availability (A:L). What does that mean for this vulnerability? An attacker using either a specially-crafted page or a content script injected into a target page can show an extension's popup over a permission prompt or screen share dialog allowing the extension to spoof parts of the prompt's UI that shows its origin.
According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do? The user would have to click on a specially crafted URL to be compromised by the attacker, and navigate to a malicious site where malicious code would execute a series of specially crafted queries.
