Is Windsurf Safe?

Last updated: January 12, 2026

An honest security analysis of Windsurf for developers considering it for their projects.

Quick Answer

Use with caution - 94 Chromium CVEs require vigilant updates

Windsurf (by Codeium) has significant security concerns: 94 Chromium CVEs were discovered in 2024-2025 security audits. While Codeium offers zero data retention mode and self-hosted options, the Chromium vulnerability count makes Cursor (VS Code-based, no major CVEs) a safer alternative for sensitive work.

Known Security Incidents

94 Chromium CVEs Discovered in Security Audit

2024-2025

Security researchers identified 94 Chromium-based vulnerabilities in Windsurf IDE, including memory corruption, sandbox escapes, and remote code execution risks. Users must keep Windsurf updated to the latest version to receive patches.

Security Assessment

Security Strengths

  • Zero Data Retention mode: Codeium claims no code storage in this mode
  • Self-hosted deployment option for enterprise (keeps AI on-premises)
  • Codeium is SOC 2 Type II certified
  • Cascade AI feature can work with local models
  • Active development - Codeium releases patches frequently

Security Concerns

  • 94 Chromium CVEs discovered in 2024-2025 security audits - far more than competitors
  • Chromium-based architecture means browser-level vulnerabilities affect the IDE
  • Electron apps like Windsurf have larger attack surface than web-based tools
  • Cascade AI sends code to cloud by default (Zero Data Retention must be enabled)
  • Updates are critical but users often delay installing them

Security Checklist for Windsurf

  • 1
    Enable auto-updates: Windsurf → Settings → Application → Check for updates automatically
  • 2
    Enable Zero Data Retention: Codeium Settings → Data Privacy → Zero Data Retention
  • 3
    For enterprise: consider Codeium's self-hosted deployment option
  • 4
    Verify version after each update: Help → About should show latest release
  • 5
    Review Cascade AI suggestions carefully before accepting
  • 6
    For highly sensitive code: consider Cursor (VS Code-based, no major CVEs) instead

The Verdict

Windsurf's 94 Chromium CVEs are a serious concern that sets it apart from competitors. While Codeium offers good privacy options (Zero Data Retention, self-hosted), the sheer number of vulnerabilities in the underlying Chromium framework makes vigilant updating essential. For security-critical work, Cursor (VS Code-based, clean security record) is a safer choice.

What Security Experts Say

There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.

It's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.

Frequently Asked Questions

What are the 94 Chromium CVEs in Windsurf?

Security researchers discovered 94 vulnerabilities in Windsurf's Chromium-based architecture during 2024-2025 audits. These include memory corruption bugs, sandbox escapes, and potential remote code execution. Codeium has released patches, but users must keep Windsurf updated.

Is Windsurf safer than Cursor?

No. Cursor (VS Code fork) has no major CVEs, while Windsurf has 94 Chromium CVEs. Cursor's architecture is more battle-tested. Both offer privacy modes, but Cursor's security track record is significantly better.

What is Codeium's Zero Data Retention mode?

Zero Data Retention is a Codeium setting that claims no code snippets are stored on their servers. Code is processed for AI suggestions but not retained. Enable it in Codeium Settings → Data Privacy. For maximum security, consider Codeium's self-hosted option.

Should I stop using Windsurf?

You can use Windsurf if you: 1) Enable auto-updates and verify they install, 2) Enable Zero Data Retention mode, 3) Review AI suggestions carefully. For highly sensitive/classified work, consider Cursor instead due to its cleaner security record.

How do I update Windsurf to patch CVEs?

Go to Help → Check for Updates, or enable auto-updates in Settings → Application. Verify your version in Help → About. Windsurf releases patches regularly, but they only protect you if installed. Check release notes for security fixes.
