GHSA-229X-22XC-2F2W

Zendframework Local file disclosure via XXE injection in Zend_XmlRpc

Zend_XmlRpc is vulnerable to XML eXternal Entity (XXE) Injection attacks. The SimpleXMLElement class (SimpleXML PHP extension) is used in an insecure way to parse XML data. External entities can be specified by adding a specific DOCTYPE element to XML-RPC requests. By exploiting this vulnerability an application may be coerced to open arbitrary files and/or TCP connections.

An XML parser processes external entity references in untrusted input, causing the server to fetch internal resources or remote URLs. Typical impact: local file disclosure, server-side request forgery, or denial of service.

GHSA-229X-22XC-2F2W has a CVSS score of 8.6 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.11.13); upgrading removes the vulnerable code path.

1. What is GHSA-229X-22XC-2F2W? GHSA-229X-22XC-2F2W is a high-severity XML external entity injection (XXE) vulnerability in zendframework/zendframework1 (composer), affecting versions >= 1.0.0, < 1.11.13. It is fixed in 1.11.13. An XML parser processes external entity references in untrusted input, causing the server to fetch internal resources or remote URLs.
2. How severe is GHSA-229X-22XC-2F2W? GHSA-229X-22XC-2F2W has a CVSS score of 8.6 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of zendframework/zendframework1 are affected by GHSA-229X-22XC-2F2W? zendframework/zendframework1 (composer) versions >= 1.0.0, < 1.11.13 is affected.
4. Is there a fix for GHSA-229X-22XC-2F2W? Yes. GHSA-229X-22XC-2F2W is fixed in 1.11.13. Upgrade to this version or later.
5. Is GHSA-229X-22XC-2F2W exploitable, and should I be worried? Whether GHSA-229X-22XC-2F2W is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether GHSA-229X-22XC-2F2W is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix GHSA-229X-22XC-2F2W? Upgrade zendframework/zendframework1 to 1.11.13 or later.
