Inadequate encryption strength in Notifications in Google Chrome on on Windows prior to 152.0.7977.65 allowed a remote attacker leveraging social engineering to bypass web origin policy via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Web origin policy bypass in Google Chrome for Windows (prior to 152.0.7977.65) stems from inadequate encryption strength in the browser's Notifications subsystem, exploitable via a crafted HTML page using social engineering. An unauthenticated remote attacker who tricks a user into visiting a malicious page can read limited cross-origin notification data, violating the same-origin boundary. …
