Obot: Server-Side Request Forgery via remote MCP server URL

CVE-2026-101064GHSA-jgh3-fggc-mcpm

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/obot-platform/obot 0.23.0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Summary In affected versions, the URL of a remote MCP server is attacker-controlled at registration and is fetched server-side with no validation of the destination. There is no guard against loopback, link-local, RFC1918 private ranges, or the cloud metadata endpoint (169.254.169.254), so a use with the Power User, Power User Plus, or Admin role can coerce Obot into making requests to internal services and to the cloud instance metadata service, and read the responses. Am I affected? You are affected if you run Obot <= v0.22.1 with authentication enabled and allow privileged users (with the Power User or higher privileges) to register remote MCP servers . The metadata-sync code path that triggers the fetch runs automatically during reconciliation, so no user interaction beyond registration is required. Details A remote server's URL (RemoteRuntimeConfig.URL) is accepted at registration after only checking that it is parseable and uses an http/https scheme — the destination is never…

# Patch Next advisory brief: CVE-2026-101064

Advisory: Obot: Server-Side Request Forgery via remote MCP server URL
IDs: CVE-2026-101064, GHSA-jgh3-fggc-mcpm
Record: https://patchnext.com/advisories/cve-2026-101064 (revision 3, source checked 26 Oct 2026, 15:29 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/obot-platform/obot 0.23.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/obot-platform/obot: affected < 0.23.0; fixed in 0.23.0

## Suggested inspection (read-only)
- Go github.com/obot-platform/obot: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/obot-platform/obot.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
