Source description

As published by the source; long descriptions are shortened.

`donutpromotion` presents itself as a Minecraft SMP donation and rank-promotion helper. The published 0.1.0 sdist instead executes an encrypted downloader before setuptools processes the package. The automated package report identified a critical `py-download-and-execute` signal at `donutpromotion/telemetry.py:99`: downloaded or embedded bytes are decrypted and passed to `exec()` with unrestricted builtins. Review of the cited path confirms the install trigger. When `setup.py` runs during build or installation, lines 6-7 import and call `donutpromotion.telemetry.check()` before `setup()` runs. `telemetry.py:19` hardcodes `https://thisisafalsepositive.st/cdn/v2/promotion/manifest.json`. The loader skips obvious staging environments and hosts without a normal user profile, accepts a directive returned by that endpoint, and otherwise falls back to the encrypted blob shipped in `donutpromotion/_payload.py`. Lines 91-99 derive keys from a hardcoded seed, authenticate and decrypt the…

# Patch Next advisory brief: mal-2026-17196

Advisory: Malicious code in donutpromotion (PyPI)
IDs: mal-2026-17196
Record: https://patchnext.com/advisories/mal-2026-17196 (revision 1, source checked 26 Oct 2026, 12:45 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 response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI donutpromotion: affected >= 0.1.0, <= 0.1.0

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on donutpromotion.
- 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.

## Sources
- Verified: https://osv.dev/vulnerability/MAL-2026-17196 (OSV record MAL-2026-17196 lists affected ranges: PyPI donutpromotion >=0.1.0 <=0.1.0)
