# Conductor: server-side request forgery in planner context fetch task

Link for people: https://infrastack.ai/live/CVE-2026-124507 (this .md is for agents)

Conductor, an open-source workflow orchestration server, lets a workflow task fetch a URL supplied as input without restricting the destination. An attacker who can start such a workflow can make the server send requests to internal addresses it can reach.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the Conductor version in use against the affected ranges: `3.32.4`, `3.33.0`, `3.34.0-rc3`, `4.0.0-alpha.1`
- Look for workflows that use the PLANNER_CONTEXT_FETCH task

## Documents

- [advisory] Vendor advisory: github.com https://github.com/conductor-oss/conductor/security/advisories/GHSA-cx7c-4mp7-rhcj

## From the sources

A vulnerability was found in conductor-oss conductor up to 3.32.4/3.33.0/3.34.0-rc3/4.0.0-alpha.1. This issue affects the function WorkflowSystemTask.start of the file PlannerContextFetchTask.java of the component PLANNER_CONTEXT_FETCH Task Handler. The manipulation of the argument url results in server-side request forgery. It is possible to launch the attack remotely. The exploit has been made public and could be used. The researcher claims to have submitted a GHSA on the repository of the project.
