CVE-2026-45244: Steipete Summarize

Medium severity, CVSS 5.4. EPSS: 0.4% chance of exploitation in the next 30 days.

Summarize prior to 0.15.1 contains a missing authorization vulnerability that allows attackers to execute browser automation actions without per-call user approval when the extension automation feature is enabled. Attackers can influence the agent through malicious page or summary content to invoke enabled extension automation tools such as navigation or debugger-backed actions, bypassing the final user approval step when a user interacts with attacker-controlled content.
