Windsurf auth

Cascade Generated OAuth Token Exposed in Code

Windsurf's Cascade assistant generated OAuth token handling code that accidentally hardcoded or logged sensitive tokens in plaintext. This creates a critical security vulnerability where authentication tokens are visible in version control history or logs.

You notice tokens in git history, environment files, or console output that Cascade created during refactoring.

Error Messages You Might See

Token: sk_live_xxxxxxxxxxxx Authentication failed: invalid_token Expired or revoked token detected
Token: sk_live_xxxxxxxxxxxxAuthentication failed: invalid_tokenExpired or revoked token detected

Common Causes

  1. Cascade generated token initialization without understanding environment variable requirements
  2. Debug logging statements left in place that log full token values
  3. Tokens hardcoded in configuration files during rapid code generation
  4. Session token management code that doesn't use secure storage mechanisms
  5. Cascade refactored auth flow without preserving token masking logic

How to Fix It

Immediately rotate all exposed tokens through your OAuth provider dashboard. Review Cascade's generated auth code and replace hardcoded tokens with environment variable references. Remove any debug logging that outputs sensitive values. Use Spring Security's token encoding mechanisms instead of raw token storage.

Frequently Asked Questions

How do I find exposed tokens in git history?

Use git-secrets or git log -p | grep -i token to search your commit history. Consider using gitguardian.com for automated scanning.

Should I revoke all tokens?

Yes, immediately revoke compromised tokens in your OAuth provider's admin panel and generate new ones.
