Zend-Form vulnerable to Cross-site Scripting
Real-World Exposure
zendframework/zend-form🐘zendframework/zend-formReal-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
Many Zend Framework 2 view helpers were using the escapeHtml() view helper in order to escape HTML attributes, instead of the more appropriate escapeHtmlAttr(). In situations where user data and/or JavaScript is used to seed attributes, this can lead to potential cross site scripting (XSS) attack vectors.
Vulnerable view helpers include:
- All
Zend\Formview helpers. - Most
Zend\Navigation(akaZend\View\Helper\Navigation\*) view helpers. - All "HTML Element" view helpers:
htmlFlash(),htmlPage(),htmlQuickTime(). Zend\View\Helper\Gravatar

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zendframework/zend-form, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update zendframework/zend-form to 2.2.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gvpp-6jrj-5pqc is resolved across your whole dependency graph.
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.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-gvpp-6jrj-5pqc can be triaged on real exposure rather than presence alone.
Tailored to GHSA-gvpp-6jrj-5pqc. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-gvpp-6jrj-5pqc in your dependencies?
O3 Security finds GHSA-gvpp-6jrj-5pqc across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
