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

An attacker can exploit phpMyAdmin before 4.8.4 to leak the contents of a local file because of an error in the transformation feature. The attacker must have access to the phpMyAdmin Configuration Storage tables, although these can easily be created in any database to which the attacker has access. An attacker must have valid credentials to log in to phpMyAdmin; this vulnerability does not allow an attacker to circumvent the login system.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update phpmyadmin/phpmyadmin to 4.8.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-19968 is resolved across your whole dependency graph.

  3. Workarounds

    Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
