How to Fix CVE-2022-40487

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

processwire/processwire fixed: Latest secure release
Upgrade processwire/processwire to Latest secure release
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 processwire/processwire

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-40487, inspect your project dependencies for Processwire/processwire:

inspect dependencies for processwire/processwire

Analyze the terminal output to locate any version of Processwire/processwire in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), 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 Processwire/processwire, 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

ProcessWire v3.0.200 was discovered to contain multiple cross-site scripting (XSS) vulnerabilities via the Search Users and Search Pages function. These vulnerabilities allow attackers to execute arbitrary web scripts or HTML via injection of a crafted payload.
