CVE-2026-26010: Leaky JWTs in OpenMetadata exposing highly-privileged bot users

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 sampleathena.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/sampleathena.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, sampleathena, though other services In the Network tab, introspect the request made to api/v1/services/ingestionPipelines, and find the jwtToken in the response: <img width="1329" height="299" alt="image" src="https://github.com/user-attachments/assets/0c405776-159e-4188-9591-ed8cc71bc596" />

Use the JWT to issue (potentially destructive) API calls <img width="3024" height="1798" alt="image" src="https://github.com/user-attachments/assets/ab40b528-4d2b-404b-8f8a-482a1693e179" />

Resulting mutated description: <img width="622" height="399" alt="image" src="https://github.com/user-attachments/assets/3fa630ff-93b5-4b7d-8e3c-220f8a84a23a" />

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

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.
