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

Description

The Drupal project uses the third-party library Archive_Tar, which has released a security improvement that is needed to protect some Drupal configurations.

Multiple vulnerabilities are possible if Drupal is configured to allow .tar, .tar.gz, .bz2 or .tlz file uploads and processes them.

The latest versions of Drupal update Archive_Tar to 1.4.9 to mitigate the file processing vulnerabilities.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update drupal/core to 7.69 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-98h9-727m-44qv 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.
