CVE-2026-124507 - Vulnerability Details

- conductor-oss conductor PLANNER_CONTEXT_FETCH Task PlannerContextFetchTask.java WorkflowSystemTask.start server-side request forgery

Description

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.

Analysis

Impact

A server‑side request forgery flaw exists in the PLANNER_CONTEXT_FETCH task handler of Conductor. The attacker can manipulate the "url" argument so that the system initiates outbound HTTP requests to arbitrary hosts, potentially exposing internal network information, stealing credentials, or pivoting to other services. The flaw allows the attacker to launch the exploit from any external client that can reach the API endpoint, making it remotely exploitable.

Affected Systems

conductor‑oss Conductor, versions up to 3.32.4, 3.33.0, 3.34.0‑rc3 and 4.0.0‑alpha.1, as these contain the vulnerable workflow task implementation.

Risk and Exploitability

The vulnerability carries a CVSS base score of 6.9, indicating moderate severity, and it has been publicly disclosed. No EPSS score is available, yet the SSRF nature means an attacker can trigger the flaw with a simple crafted request to WorkflowSystemTask.start. It is not yet listed in the CISA KEV catalog, but the potential for data exfiltration or internal pivot makes it a significant risk for exposed deployments.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Upgrade Conductor to a release that no longer contains the vulnerable PLANNER_CONTEXT_FETCH task handler (any version newer than 4.0.0‑alpha.1).
Configure the application to whitelist outbound URLs or restrict the "url" parameter to a safe set of internal addresses to mitigate unintended requests.
Enforce strict authentication and enforce role‑based access controls so that only authorized users can invoke the WorkflowSystemTask.start endpoint.
Monitor outbound traffic and server logs for unexpected external requests that could indicate exploitation attempts.
