How to Fix GHSA-3fgr-xjr6-xqm8

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

phpxmlrpc/phpxmlrpc fixed: 4.9.0 
Upgrade phpxmlrpc/phpxmlrpc to 4.9.0
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 phpxmlrpc/phpxmlrpc

How to Check if You Are Affected

To determine whether your application is affected by GHSA-3fgr-xjr6-xqm8, inspect your project dependencies for Phpxmlrpc/phpxmlrpc:

inspect dependencies for phpxmlrpc/phpxmlrpc

Analyze the terminal output to locate any version of Phpxmlrpc/phpxmlrpc in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.9.0), 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-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection'), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval"). In Phpxmlrpc/phpxmlrpc, 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

code injection in `Wrapper::buildClientWrapperCode` via manipulation of the `$client` argument. It was possible to force the client to access local files or connect to undesired urls instead of the intended target server's url.
