CVE-2025-62716
📋 TL;DR
An open redirect vulnerability in Plane project management software allows attackers to inject malicious JavaScript via the ?next_path query parameter, leading to cross-site scripting (XSS). This enables execution of arbitrary code in victims' browsers without authentication, affecting all users of vulnerable versions. The vulnerability can lead to data theft, session hijacking, and administrative privilege escalation.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of Plane instance: attackers steal sensitive project data, hijack administrator sessions, modify system settings, and potentially pivot to internal networks.
Likely Case
Session hijacking and data exfiltration: attackers steal authentication cookies and sensitive project information from logged-in users.
If Mitigated
Limited impact with proper network segmentation and user awareness training, though vulnerability remains exploitable.
🎯 Exploit Status
Exploitation requires only a crafted URL with malicious JavaScript in the next_path parameter.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.1.0
Vendor Advisory: https://github.com/makeplane/plane/security/advisories/GHSA-6fj7-xgpg-mj6f
Restart Required: Yes
Instructions:
1. Backup your Plane instance data. 2. Update to version 1.1.0 or later using your deployment method (Docker, manual, etc.). 3. Restart the Plane service. 4. Verify the update was successful.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rule
allBlock requests containing javascript: scheme in query parameters
Reverse Proxy Filtering
allConfigure reverse proxy to sanitize or block malicious next_path parameters
🧯 If You Can't Patch
- Isolate vulnerable Plane instances behind network segmentation
- Implement strict Content Security Policy (CSP) headers to mitigate XSS impact
🔍 How to Verify
Check if Vulnerable:
Check if Plane version is below 1.1.0 in admin interface or deployment configurationCheck Version:
Check Plane web interface settings or docker inspect for versionVerify Fix Applied:
Confirm version is 1.1.0 or higher and test that javascript: scheme in next_path parameter no longer executes📡 Detection & Monitoring
