CVE-2024-22262
📋 TL;DR
This vulnerability in Spring Framework's UriComponentsBuilder allows attackers to bypass URL host validation through specially crafted input. Applications that parse external URLs with UriComponentsBuilder and perform host validation are vulnerable to open redirect or SSRF attacks. This affects Spring applications using vulnerable versions of the framework.
💻 Affected Systems
- Spring Framework
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers could redirect users to malicious sites (open redirect) or make internal network requests to sensitive systems (SSRF), potentially accessing internal services or exfiltrating data.
Likely Case
Open redirect attacks leading to phishing sites or SSRF attacks against internal services accessible from the vulnerable application.
If Mitigated
Limited impact with proper input validation, network segmentation, and URL allowlisting.
🎯 Exploit Status
Similar to CVE-2024-22259 and CVE-2024-22243 with different input vectors. Attack requires specific application patterns but is straightforward once identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Spring Framework 6.1.5, 6.0.18, 5.3.33
Vendor Advisory: https://spring.io/security/cve-2024-22262
Restart Required: Yes
Instructions:
1. Update Spring Framework to patched version. 2. Update dependencies in build configuration (Maven/Gradle). 3. Rebuild and redeploy application. 4. Restart application servers.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement additional validation of parsed URL components before using them.
URL Allowlisting
allRestrict allowed URL hosts/schemes to a predefined allowlist.
🧯 If You Can't Patch
- Implement strict input validation for all URL parameters
- Use network controls to restrict outbound connections from application servers
🔍 How to Verify
Check if Vulnerable:
Check if application uses UriComponentsBuilder to parse external URLs and performs host validation. Review code for UriComponentsBuilder usage with user-supplied input.Check Version:
Check pom.xml or build.gradle for Spring Framework version, or use: java -cp [application.jar] org.springframework.boot.loader.JarLauncher --versionVerify Fix Applied:
Verify Spring Framework version is 6.1.5+, 6.0.18+, or 5.3.33+. Test URL parsing functionality with malicious inputs.📡 Detection & Monitoring
