Privilege escalation through a malicious extension
Published Jul 30, 2026 · Updated Jul 30, 2026
Improper input validation in Google Chrome DevTools before 151.0.7922.72 allows attackers to escalate privileges through a crafted extension. Google identifies DevTools as the affected component but has not disclosed the validation locus, accepted untrusted value, or privileged operation it reaches. Exploitation requires convincing a user to install the malicious extension; the published record does not specify which browser privileges or resources become accessible.
