Trojanized pantheon-agents 0.6.1 and 0.6.2 on PyPI ship a credential stealer (supply-chain account compromise)

GHSA-93qj-5q5v-3c2h

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (pantheon-agents 0.6.4), 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 The PyPI account that publishes pantheon-agents was compromised in the June 2026 "Hades" PyPI supply-chain attack (Mini Shai-Hulud / Miasma lineage). The attacker used a stolen, long-lived PyPI API token to upload trojanized releases pantheon-agents 0.6.1 and 0.6.2 directly to PyPI. Only the PyPI artifacts are affected. The GitHub source repository, its git tags, and all other distribution channels are clean — no malicious code was committed to the repository. Affected - pantheon-agents 0.6.1 and 0.6.2 on PyPI. Not affected: installs from the GitHub source, version 0.6.0 and earlier, and the Desktop / Online apps. Indicators of compromise The malicious wheels ship a -setup.pth file that executes on Python startup. It downloads the Bun JavaScript runtime and runs an obfuscated credential stealer (index.js) that harvests and exfiltrates credentials reachable from the host — environment variables, ~/.pypirc, ~/.npmrc, cloud credentials (~/.aws, etc.), SSH keys, and API tokens.…

# Patch Next advisory brief: GHSA-93qj-5q5v-3c2h

Advisory: Trojanized pantheon-agents 0.6.1 and 0.6.2 on PyPI ship a credential stealer (supply-chain account compromise)
IDs: GHSA-93qj-5q5v-3c2h
Record: https://patchnext.com/advisories/ghsa-93qj-5q5v-3c2h (revision 3, source checked 26 Oct 2026, 13:50 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: pantheon-agents 0.6.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI pantheon-agents: affected >= 0.6.1, <= 0.6.2; fixed in 0.6.4

## Suggested inspection (read-only)
- `python -m pip show pantheon-agents`: prints the installed version. Run with the environment that serves production active.

## 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 pantheon-agents.
- 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.
