Summary
Policy bypass in Extensions in Google Chrome prior to 142.0.7444.59 allowed an attacker who convinced a user to install a malicious extension to leak cross-origin data via a crafted Chrome Extension. (Chromium security severity: Low)
Risk Assessment
A user could be tricked into installing a malicious extension, leading to leakage of data from other origins. This may compromise user data confidentiality.
