CVE-2025-24891
📋 TL;DR
CVE-2025-24891 is a critical path traversal vulnerability in Dumb Drop file upload application that allows authenticated users to overwrite arbitrary system files. Since the container runs as root by default, attackers can inject malicious payloads into scheduled tasks or service files, potentially gaining root access. This affects all Dumb Drop deployments, especially those without authentication enabled.
💻 Affected Systems
- Dumb Drop
⚠️ 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).

- 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 root access, allowing attackers to execute arbitrary code, steal data, or maintain persistent access.
Likely Case
Attackers gain root privileges on the container, potentially compromising the host system through container escape techniques.
If Mitigated
Limited to file corruption or denial of service if proper file permissions and container isolation are implemented.
🎯 Exploit Status
Exploitation requires upload permissions, but authentication may be disabled by default. Path traversal payloads can be crafted to target critical system files.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version containing commit cb586316648ccbfb21d27b84e90d72ccead9819d
Vendor Advisory: https://github.com/DumbWareio/DumbDrop/security/advisories/GHSA-24f2-fv38-3274
Restart Required: No
Instructions:
1. Update to the latest Dumb Drop version. 2. Verify the fix commit cb586316648ccbfb21d27b84e90d72ccead9819d is present. 3. Restart the service if using container orchestration.
🔧 Temporary Workarounds
Enable authentication
allRequire authentication for all upload operations to limit attack surface.
Configure Dumb Drop with authentication enabled according to documentation
Run container as non-root user
dockerRun the container with a non-privileged user to limit file overwrite capabilities.
docker run --user 1000:1000 dumbdrop
🧯 If You Can't Patch
- Disable file upload functionality entirely
- Implement strict network access controls to limit who can access the service
