CVE-2025-60540
📋 TL;DR
karakeep versions v0.26.0 to v0.7.0 contain a Server-Side Request Forgery (SSRF) vulnerability that allows attackers to make unauthorized requests from the server to internal or external systems. This affects all deployments running vulnerable versions of karakeep, potentially exposing internal network resources or enabling data exfiltration.

- 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
Attacker accesses internal services, exfiltrates sensitive data, or performs lateral movement within the network by making the vulnerable server proxy requests to internal systems.
Likely Case
Information disclosure from internal services, scanning of internal network resources, or limited data exfiltration through the vulnerable server.
If Mitigated
Limited impact with proper network segmentation and egress filtering, potentially only allowing requests to specific allowed endpoints.
🎯 Exploit Status
Exploitation requires understanding of the vulnerable endpoint and ability to craft SSRF payloads.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v0.26.1 or later
Vendor Advisory: https://github.com/karakeep-app/karakeep/
Restart Required: No
Instructions:
1. Update karakeep to version v0.26.1 or later. 2. Verify the update was successful by checking the version. 3. No restart required for typical deployments.
🔧 Temporary Workarounds
Network Egress Filtering
allImplement network-level restrictions to limit outbound connections from the karakeep server to only necessary external services.
Input Validation
allAdd input validation to reject URLs pointing to internal IP ranges (127.0.0.1, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) and localhost.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the karakeep server from sensitive internal systems
- Deploy a web application firewall (WAF) with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Check karakeep version. If between v0.26.0 and v0.7.0 inclusive, the system is vulnerable.Check Version:
karakeep --versionVerify Fix Applied:
Verify karakeep version is v0.26.1 or later and test the previously vulnerable endpoint with SSRF payloads.📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP requests from karakeep server
- Requests to internal IP addresses or localhost from karakeep
Network Indicators:
- Unexpected HTTP traffic from karakeep server to internal network segments
- Multiple rapid requests to different internal IPs
SIEM Query:
source="karakeep" AND (dest_ip=127.0.0.1 OR dest_ip IN (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16))
