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 default error handling view script generated using Zend_Tool failed to escape request parameters when run in the "development" configuration environment, providing a potential XSS attack vector.

Zend_Tool_Project_Context_Zf_ViewScriptFile was patched such that the view script template now calls the escape() method on dumped request variables.

Zend Framework 1.11.4 includes a patch that adds escaping to the generated error/error.phtml view script, ensuring that request variables are escaped appropriately for the browser. Do note, however, that this will not update any previously generated code. You will still need to follow the next advice for previously generated error view scripts.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zendframework/zendframework1, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update zendframework/zendframework1 to 1.11.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g52p-86j5-xr8q is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
