🐕 Corgea issued a PR to fix a vulnerability found in data/static/codefixes/redirectCryptoCurrencyChallenge_3_correct.ts.
It is CWE-601: URL Redirection to Untrusted Site ('Open Redirect') that has a severity of 🔴 High.
🪄 Fix explanation
The fix changes the URL comparison from using "includes" to "===", ensuring only exact matches from the allowlist are redirected, preventing open redirect vulnerabilities.
- The original code used "url.includes(allowedUrl)", which allowed partial matches, enabling potential redirects to malicious sites.
- The fix replaces "includes" with "===", ensuring only exact URL matches from the "redirectAllowlist" are permitted.
- This change prevents attackers from exploiting partial URL matches to redirect users to untrusted sites.
- The "redirectAllowlist" now strictly controls which URLs are considered safe for redirection.
💡 Important Instructions
Ensure the
redirectAllowlistcontains all necessary URLs for legitimate redirects, as only exact matches will be allowed.See the issue and fix in Corgea.
