CVE-2026-45245 · Summarize < 0.15.1 Unauthorized Daemon Request via Untrusted Events
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Summarize prior to 0.15.1 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.
