How to Fix GHSA-4j9x-g4x8-vcmf

To remediate this vulnerability, upgrade all affected Zendframework/zendframework1 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

zendframework/zendframework1 fixed: 1.11.15 
Upgrade zendframework/zendframework1 to 1.11.15
zendframework/zendframework1 fixed: 1.12.1 
Upgrade zendframework/zendframework1 to 1.12.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for zendframework/zendframework1

How to Check if You Are Affected

To determine whether your application is affected by GHSA-4j9x-g4x8-vcmf, inspect your project dependencies for Zendframework/zendframework1:

inspect dependencies for zendframework/zendframework1

Analyze the terminal output to locate any version of Zendframework/zendframework1 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.11.15), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-611: Improper Restriction of XML External Entity Reference, where the product processes an xml document that can contain xml entities with uris that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. In Zendframework/zendframework1, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

`Zend_Feed_Rss` and `Zend_Feed_Atom` were found to contain potential XML eXternal Entity (XXE) vectors due to insecure usage of PHP's DOM extension. External entities could be specified by adding a specific DOCTYPE element to feeds; exploiting this vulnerability could coerce opening arbitrary files and/or TCP connections. A similar issue was fixed for 1.11.13 and 1.12.0, in the `Zend_Feed::import()` factory method; however, the reporter of the issue discovered that the individual classes contained similar functionality in their constructors which remained vulnerable.
