Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Zendframework/zendframework1 versions 1.12.0 up to 1.12.4 are affected by XML external entity (XXE) injection and entity expansion weaknesses in components that use PHP's DOMDocument, SimpleXML, and xml_parse. An attacker who can supply XML documents or strings to the application can force it to read arbitrary files or open TCP connections, or cause denial of service through recursive entity definitions. Upgrade to zendframework/zendframework1 version 1.12.4 or later.
