Leaky JWTs in OpenMetadata exposing highly-privileged bot users

High severity GitHub Reviewed Published Feb 11, 2026 in open-metadata/OpenMetadata • Updated Feb 11, 2026

Package

maven org.open-metadata:openmetadata-sdk (Maven)

Affected versions

< 1.11.8

Patched versions

Description

Summary

Calls issued by the UI against /api/v1/ingestionPipelines leak JWTs used by ingestion-bot for certain services (Glue / Redshift / Postgres)

Details

Any read-only user can gain access to a highly privileged account, typically which has the Ingestion Bot Role. This enables destructive changes in OpenMetadata instances, and potential data leakage (e.g. sample data, or service metadata which would be unavailable per roles/policies).

PoC

I was able to extract the JWT used by the bot/agent populating sample_athena.default in the Collate Sandbox. To prove this out, I mutated the description to this UUID: fe2e4cc1-da72-4acf-8535-112a3cfa9c7e, which you can see @ https://sandbox.open-metadata.org/database/sample_athena.default.

Steps to Reproduce

  • Create a Collate Sandbox account; these are non-admin accounts by default with minimal permissions.
  • Open the Developer Console
  • Go to the Services Page. In this case, sample_athena, though other services
  • In the Network tab, introspect the request made to api/v1/services/ingestionPipelines, and find the jwtToken in the response:

  • Use the JWT to issue (potentially destructive) API calls

  • Resulting mutated description:

Note that this is also the case for these services, among others:

Proposed Remediation

Redact jwtToken in API payload.
Implement role-based filtering - Only return JWT tokens to users with explicit admin/service account permissions
(for Admins) Rotate Ingestion Bot Tokens in affected environments

Impact

What kind of vulnerability is it? Who is impacted?

  • Vulnerability Type: Privilege Escalation
  • Risk: User impersonation, even for those with read-only access, can lead to destructive outcomes if malicious actors leverage the leaked JWT.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Improper Privilege Management

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Learn more on MITRE.
