CVE-2025-13158
📋 TL;DR
This CVE describes a prototype pollution vulnerability in apidoc-core that allows remote attackers to modify JavaScript object prototypes through malformed data structures. This can lead to denial of service or unintended behavior in applications that rely on the integrity of prototype chains. Anyone using apidoc-core versions 0.2.0 or later is affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete application compromise leading to remote code execution, data manipulation, or persistent denial of service across the entire application.
Likely Case
Application instability, denial of service, or unexpected behavior due to prototype chain corruption affecting multiple objects.
If Mitigated
Limited impact with proper input validation and sanitization, potentially causing only localized errors.
🎯 Exploit Status
Exploitation requires sending malformed data structures with the 'define' property to vulnerable endpoints.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://www.sonatype.com/security-advisories/cve-2025-13158
Restart Required: Yes
Instructions:
1. Monitor the apidoc-core repository for security updates. 2. Apply the patch when available. 3. Restart all affected services.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation to reject malformed data structures containing the 'define' property.
Object.freeze() on Prototypes
allUse Object.freeze() on critical object prototypes to prevent modification.
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all user-supplied data.
- Use web application firewalls (WAF) to block requests containing suspicious prototype pollution patterns.
🔍 How to Verify
Check if Vulnerable:
Check package.json for apidoc-core version 0.2.0 or higher.Check Version:
npm list apidoc-coreVerify Fix Applied:
Verify that the apidoc-core version has been updated to a patched version when available.📡 Detection & Monitoring
Log Indicators:
- Unusual error messages related to prototype chains
- Application crashes or unexpected behavior in api_group.js, api_param_title.js, api_use.js, or api_permission.js modules
Network Indicators:
- HTTP requests containing malformed JSON with 'define' property
- Unusual spikes in error responses from API endpoints
SIEM Query:
source="application_logs" AND ("prototype" OR "define" OR "api_group" OR "api_param_title" OR "api_use" OR "api_permission") AND ("error" OR "crash")
