Zendframework Denial of Service vector via XEE injection
Real-World Exposure
zendframework/zendframework1Real-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_Dom, Zend_Feed, Zend_Soap, and Zend_XmlRpc are vulnerable to XML Entity Expansion (XEE) vectors, leading to Denial of Service vectors. XEE attacks occur when the XML DOCTYPE declaration includes XML entity definitions that contain either recursive or circular references; this leads to CPU and memory consumption, making Denial of Service exploits trivial to implement.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update zendframework/zendframework1 to 1.11.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2jx7-xg83-j2m7 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-2jx7-xg83-j2m7 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-2jx7-xg83-j2m7. 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-2jx7-xg83-j2m7 in your dependencies?
O3 Security finds GHSA-2jx7-xg83-j2m7 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
