dmlc/dgl Vulnerable to Remote Code Execution by Pickle Deserialization via rpc.recv_request()

GHSA-3x5x-fw77-g54c

What to do

Vendor response not established. Follow the primary source's mitigation guidance and check back for a fix.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Impact Dgl implements rpc server (startserver() in rpcserver.py) for supporting the RPC communications among different remote users over networks. It relies on pickle serialize and deserialize to pack and unpack network messages. The is a known risk in pickle deserialization functionality that can be used for remote code execution. Patches TBD. Workarounds When running DGL distributed training and inference (DistDGL) make sure you do not assign public IPs to any instance in the cluster.

# Patch Next advisory brief: GHSA-3x5x-fw77-g54c

Advisory: dmlc/dgl Vulnerable to Remote Code Execution by Pickle Deserialization via rpc.recv_request()
IDs: GHSA-3x5x-fw77-g54c
Record: https://patchnext.com/advisories/ghsa-3x5x-fw77-g54c (revision 3, source checked 26 Oct 2026, 13:31 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI dgl: affected <= 2.4.0

## Suggested inspection (read-only)
- `python -m pip show dgl`: prints the installed version. Run with the environment that serves production active.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on dgl.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
