GHSA-2r69-qgv3-hr65
Summarize's hover summary feature allows malicious pages to dispatch synthetic mouseover events over attacker-controlled links
Quick fix
GHSA-2r69-qgv3-hr65 — @steipete/summarize: upgrade to the fixed version with the command below.
npm install @steipete/summarize@0.15.1Details
Summarize prior to 0.15.0 contains a vulnerability in the hover summary feature that allows malicious pages to dispatch synthetic mouseover events over attacker-controlled links, causing the extension to make authenticated daemon requests using stored tokens without verifying event trustworthiness. Attackers can place local or private-network URLs behind hoverable links to route authenticated requests through the daemon, potentially accessing sensitive internal endpoints when users interact with attacker-controlled content.
