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

Zend_Json_Encoder was not taking into account the solidus character (/) during encoding, leading to incompatibilities with the JSON specification, and opening the potential for XSS or HTML injection attacks when returning HTML within a JSON string.

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 1.7.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vvm3-rv48-j3g5 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.
