To remediate this vulnerability, upgrade all affected Zendframework/zend xmlrpc dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade zendframework/zend-xmlrpc to 2.1.6Upgrade zendframework/zend-xmlrpc to 2.2.6Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for zendframework/zend-xmlrpcHow to Check if You Are Affected
To determine whether your application is affected by GHSA-f4fj-q6m4-cc52, inspect your project dependencies for Zendframework/zend xmlrpc:
inspect dependencies for zendframework/zend-xmlrpcAnalyze the terminal output to locate any version of Zendframework/zend xmlrpc in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.6), 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-776: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion'), where the product uses xml documents and allows their structure to be defined with a document type definition (dtd), but it does not properly control the number of recursive definitions of entities. In Zendframework/zend xmlrpc, 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.

"details" : "Numerous components utilizing PHP's DOMDocument, SimpleXML, and xml_parse functionality are vulnerable to two types of attacks:\n\n- XML eXternal Entity (XXE) Injection attacks. The above mentioned extensions are insecure by default, allowing external entities to be specified by adding a specific DOCTYPE element to XML documents and strings. By exploiting this vulnerability an application may be coerced to open arbitrary files and/or TCP connections.\n- XML Entity Expansion (XEE) vectors, leading to Denial of Service vectors. XEE attacks occur when the XML DOCTYPE declaration includes XML entity definitions that contain either recursive or circular references; this leads to CPU and memory consumption, making Denial of Service exploits trivial to implement.",
