How to Fix GHSA-hg35-vqp3-fv39

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: 1.9.7 
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-hg35-vqp3-fv39, 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 1.9.7), 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

A number of classes, primarily within the `Zend_Form`, `Zend_Filter`, `Zend_Form`, `Zend_Log` and `Zend_View components`, contained character encoding inconsistencies whereby calls to the `htmlspecialchars()` and htmlentities() functions used undefined or hard coded charset parameters. In many of these cases developers were unable to set a character encoding of their choice. These inconsistencies could, in specific circumstances, allow certain multibyte representations of special HTML characters pass through unescaped leaving applications potentially vulnerable to cross-site scripting (XSS) exploits. Such exploits would only be possible if a developer used a non-typical character encoding (such as UTF-7), allowed users to define the character encoding, or served HTML documents without a valid character set defined.
