CVE-2025-62368

9.0 CRITICAL

📋 TL;DR

This CVE describes a remote code execution vulnerability in Taiga project management platform due to unsafe deserialization of untrusted data in the API. Attackers can execute arbitrary code on affected systems by sending malicious serialized data. All organizations running Taiga versions 6.8.3 and earlier are affected.

💻 Affected Systems

Products:
  • Taiga
Versions: 6.8.3 and earlier
Operating Systems: All platforms running Taiga
Default Config Vulnerable: ⚠️ Yes
Notes: All deployments of affected Taiga versions are vulnerable regardless of configuration.

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise allowing attackers to execute arbitrary commands, steal sensitive data, deploy ransomware, or pivot to other systems in the network.

🟠

Likely Case

Attackers gain shell access to the Taiga server, potentially accessing project data, user credentials, and using the system as a foothold for further attacks.

🟢

If Mitigated

If proper network segmentation and least privilege are implemented, impact may be limited to the Taiga application and its data, though RCE still represents critical risk.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires understanding of Taiga's API and deserialization mechanisms. The advisory suggests authentication may be required, but this is not explicitly confirmed.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 6.9.0

Vendor Advisory: https://github.com/taigaio/taiga-back/security/advisories/GHSA-cpcf-9276-fwc5

Restart Required: Yes

Instructions:

1. Backup your Taiga instance and database. 2. Update to Taiga version 6.9.0 or later. 3. Restart the Taiga services. 4. Verify the update was successful.

🔧 Temporary Workarounds

Network Access Restriction

all

Restrict network access to Taiga API endpoints to only trusted sources

Web Application Firewall

all

Deploy WAF with rules to detect and block serialized object attacks

🧯 If You Can't Patch

  • Isolate the Taiga instance in a separate network segment with strict egress filtering
  • Implement strict authentication and authorization controls, monitoring all API access

🔍 How to Verify

Check if Vulnerable:

Check Taiga version via web interface or by examining the installation directory. Versions 6.8.3 and earlier are vulnerable.

Check Version:

Check Taiga web interface or examine package/installation version

Verify Fix Applied:

Confirm Taiga version is 6.9.0 or later and verify the API endpoints are functioning normally.

📡 Detection & Monitoring

Log Indicators:

  • Unusual API requests with serialized data patterns
  • Unexpected process execution from Taiga user context
  • Authentication attempts followed by unusual API calls

Network Indicators:

  • HTTP POST requests to Taiga API endpoints containing serialized object patterns
  • Outbound connections from Taiga server to unexpected destinations

SIEM Query:

source="taiga" AND (http_method="POST" AND uri_path="/api/*" AND (content CONTAINS "serialized" OR content CONTAINS "pickle" OR content CONTAINS "yaml"))
