How to Fix GHSA-4vf6-mq7w-3hp6

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: 1.7.9 
Upgrade zendframework/zendframework1 to 1.7.9
zendframework/zendframework1 fixed: 1.8.5 
Upgrade zendframework/zendframework1 to 1.8.5
zendframework/zendframework1 fixed: 1.9.7 
Upgrade zendframework/zendframework1 to 1.9.7
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-4vf6-mq7w-3hp6, 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 1.7.9), 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. 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_Filter_StripTags contained an optional setting to allow whitelisting HTML comments in filtered text. Microsoft Internet Explorer and several other browsers allow developers to create conditional functionality via HTML comments, including execution of script events and rendering of additional commented markup. By allowing whitelisting of HTML comments, a malicious user could potentially include XSS exploits within HTML comments that would then be rendered in the final output.
