Content security policy bypass via malicious extension
Published Jun 30, 2026 · Updated Jun 30, 2026
Content security policy bypass in Google Chrome before 150.0.7871.47 allows attackers to evade extension script restrictions. The Extensions component insufficiently enforces content security policy for a crafted Chrome extension, but Google has not published the affected code path or incorrect policy decision. Exploitation requires a user to install the malicious extension; the disclosed consequence is limited to bypassing that extension's content restrictions.
