Summary
Between 2026-02 and 2026-04-24 a total of 22 public PyPI sdists of
ogham-mcp contained development credentials embedded in source files. All credentials have since been rotated on the respective providers. No known exploitation. Upgrade to v0.11.1 to get a clean release.What was leaked
| Credential | Location in sdist | Vulnerable range | Count |
|---|---|---|---|
| 3x Neon postgres URLs with passwords (US / EU / AP development databases) | top-level Makefile (NEON US, NEON EU, NEON AP vars) | >=0.6.5, <0.11.0 | 21 sdists |
1x Voyage AI API key (pa-...) | tests/test hooks.py::test mask secrets key value -- test fixture that fed a real key into the redaction-function tester | >=0.6.3, <0.11.1 | 22 sdists |
Impact
- Primary risk: any consumer of the affected sdists could have extracted the credentials and used them. The Neon URLs pointed at development databases; the Voyage key was a rate-limited API key.
- Observed exploitation: none detected. Audit logs on both providers were reviewed post-rotation.
- Remediation on our side:
- Neon passwords for all three regions rotated.
- Voyage API key rotated.
- All affected versions yanked from PyPI (v0.3.0 through v0.10.4 yanked on 2026-04-24; v0.11.0 pending yank after this advisory).
- v0.11.0 removed the Neon URLs and introduced
make publish-checkwhich scans every sdist for credential patterns before upload. - v0.11.1 scrubs the Voyage key from the test fixture and excludes
benchmarks/,docs/,research/,extras/, and**/*.env*from all future sdists via explicit hatchling sdist include/exclude inpyproject.toml.
Action for users
- If users installed any version from
v0.3.0throughv0.11.0, upgrade to v0.11.1 immediately:
pip install --upgrade "ogham-mcp>=0.11.1"- Users do not need to rotate anything on their end. The leaked credentials were owned by the project maintainer, not by users.

Discovered during an internal pre-release audit on 2026-04-24 while preparing v0.11.1.
