Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

Ansible before 1.5.5 sets 0644 permissions for sources.list, which might allow local users to obtain sensitive credential information in opportunistic circumstances by reading a file that uses the "deb http://user:pass@server:port/" format.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ansible, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update ansible to 1.5.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6667-f46p-pg88 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Frequently Asked Questions

Ansible before 1.5.5 sets 0644 permissions for `sources.list`, which might allow local users to obtain sensitive credential information in opportunistic circumstances by reading a file that uses the `&quot;deb http://user:pass@server:port/&quot;` format.
