CVE-2026-45244: Summarize < 0.15.1 Unapproved Browser Automation Execution

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.

Security readout for executives and security teams

Plain-English summary

Summarize before 0.15.1 could let malicious web or summary content cause enabled browser automation actions without the expected final user approval. This matters where staff use the extension automation feature while interacting with untrusted content.

Executive priority

Treat as a timely but moderate-risk endpoint and browser-extension issue. Prioritize users who rely on Summarize automation against external web content, because the vulnerability weakens a user approval control.

Technical view

The issue is a missing authorization flaw, CWE-862, in Summarize prior to 0.15.1. When extension automation is enabled, attacker-influenced content could invoke automation tools such as navigation or debugger-backed actions without per-call approval. CVSS is 5.4 with low confidentiality and integrity impact.

Likely exposure

Exposure appears limited to Summarize installations before 0.15.1 with extension automation enabled, especially users who process or browse attacker-controlled content. Systems not using that feature are less likely to be exposed based on the provided evidence.

Exploitation context

The bundle does not show CISA KEV listing or cited active exploitation. Exploitation requires user interaction with attacker-controlled content and depends on enabled automation tooling. The likely impact is unauthorized browser actions, not direct server compromise.

Researcher notes

Key constraints are UI:R, PR:N, network attack vector, and no availability impact. Research should focus on authorization boundaries around automation tool invocation and whether approval checks consistently apply before navigation or debugger-backed actions.

Mitigation direction

  • Upgrade Summarize to 0.15.1 or later; consider the latest vendor release.
  • Disable extension automation until upgraded if immediate patching is not possible.
  • Review the linked vendor patch, pull request, and release notes.
  • Limit use of automation features on untrusted pages or summaries.

Validation and detection

  • Inventory Summarize versions and flag any installation before 0.15.1.
  • Confirm whether extension automation is enabled for affected users.
  • Review browser or extension activity for unexpected automation after untrusted content interaction.
  • Verify upgraded clients no longer allow automation without per-call approval.
