CVE-2025-46183
📋 TL;DR
CVE-2025-46183 is a deserialization vulnerability in pgCodeKeeper's Utils.deserialize function that allows remote code execution when processing malicious .ser files. Attackers can execute arbitrary code on systems running vulnerable versions. This affects all users of pgCodeKeeper 10.12.0 who process untrusted serialized data.
💻 Affected Systems
- pgCodeKeeper
⚠️ 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).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control over the target system, data exfiltration, and lateral movement within the network.
Likely Case
Remote code execution leading to data theft, installation of backdoors, or ransomware deployment on affected systems.
If Mitigated
Limited impact with proper input validation and network segmentation preventing successful exploitation.
🎯 Exploit Status
Exploitation requires attacker to provide a malicious .ser file to the vulnerable deserialization function.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Monitor vendor for security updates
2. Apply patch when available
3. Test in non-production environment first
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict validation of .ser files before processing through Utils.deserialize function
Network Segmentation
allIsolate pgCodeKeeper instances from untrusted networks and implement strict firewall rules
🧯 If You Can't Patch
- Disable processing of .ser files from untrusted sources in pgCodeKeeper configuration
- Implement application-level allowlisting for trusted serialized data sources only
🔍 How to Verify
Check if Vulnerable:
Check if pgCodeKeeper version is 10.12.0 and if Utils.deserialize function processes external .ser filesCheck Version:
Check pgCodeKeeper about or version information in application interfaceVerify Fix Applied:
Verify pgCodeKeeper version is updated beyond 10.12.0 when patch becomes available📡 Detection & Monitoring
Log Indicators:
- Unusual .ser file processing activity
- Unexpected process execution from pgCodeKeeper context
- Deserialization errors or exceptions
Network Indicators:
- Unexpected outbound connections from pgCodeKeeper host
- File transfers to/from pgCodeKeeper service
SIEM Query:
