Summary

OpsTree REMS through 1.0.0 contains a missing authentication vulnerability that allows unauthenticated remote attackers to access Governance API endpoints, including /api/v1/databases. Attackers can send requests without an Authorization header, or with invalid or tampered JWT tokens, to retrieve stored database hosts, usernames, and passwords.

Who should check

Teams running OpsTree REMS version 1.0.0 or earlier, including any REMS deployment exposing the Governance API

Check your systems with an agent

Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.

Check whether my systems are affected by CVE-2026-126769 (OpsTree REMS through 1.0.0 Missing Authentication via /api/v1/databases Governance API), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-126769 (entry last updated 2026-11-11):
Affected:
- OpsTree Solutions REMS: through 1.0.0
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Running REMS version 1.0.0 or earlier (source: https://www.vulncheck.com/advisories/opstree-rems-through-1.0.0-missing-authentication-via-api-v1-databases-governance-api)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, no login, no user action.
CISA KEV: CVE-2026-126769 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126769 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
- https://gist.github.com/neelkotnis/3fc4a8587179a8691ed89056ea7df076
- https://opstree.com/rems-ai-powered-observability/
- https://www.vulncheck.com/advisories/opstree-rems-through-1.0.0-missing-authentication-via-api-v1-databases-governance-api
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

Questions about CVE-2026-126769

Is CVE-2026-126769 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data

What does this mean?

The REMS Governance API at /api/v1/databases does not require authentication. Someone without a login can retrieve stored database hosts, usernames, and passwords.Source: vulncheck.com

Which versions are affected by CVE-2026-126769?

REMS: through 1.0.0.Source: cve.now feed data

Am I affected, and how do I check?

REMS version 1.0.0 and earlier are affected, per the listed range from the first release through 1.0.0. To check a deployment, look up the installed REMS version and confirm whether the /api/v1/databases endpoint is reachable.Source: vulncheck.com

How do I fix CVE-2026-126769?

No fixed version is listed in the checked facts, so no specific upgrade target can be named. Check the vendor's release channels for a newer version beyond 1.0.0.Source: vulncheck.com

What if there's no patch?

The facts do not describe a workaround. Limiting network access to the REMS Governance API so that /api/v1/databases is not reachable by untrusted clients is a general step that reduces exposure while no fix is available.Source: vulncheck.com
