MEDIUMGHSA-fh7r-58q4-6387 is a medium-severity (CVSS 4.7) vulnerability in zendframework/zendframework. A fix is available for zendframework/zendframework — see the affected versions and patch details below.
Zendframework URL Rewrite vulnerability
Real-World Exposure
zendframework/zendframeworkReal-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-diactoros (and, by extension, Expressive), zend-http (and, by extension, Zend Framework MVC projects), and zend-feed (specifically, its PubSubHubbub sub-component) each contain a potential URL rewrite exploit. In each case, marshaling a request URI includes logic that introspects HTTP request headers that are specific to a given server-side URL rewrite mechanism.
When these headers are present on systems not running the specific URL rewriting mechanism, the logic would still trigger, allowing a malicious client or proxy to emulate the headers to request arbitrary content.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zendframework/zendframework, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update zendframework/zendframework to 2.5.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fh7r-58q4-6387 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-fh7r-58q4-6387 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-fh7r-58q4-6387. 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-fh7r-58q4-6387 in your dependencies?
O3 Security finds GHSA-fh7r-58q4-6387 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
