CVE-2024-34393 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. libxmljs2 is vulnerable to a type confusion vulnerability when parsing a specially crafted XML while invoking a function on the result of attrs() that was called on a parsed node. This vulnerability might lead to denial of service (on both 32-bit systems and 64-bit systems), data leak, infinite loop and remote code execution (on 32-bit systems with the XML_PARSE_HUGE flag enabled).. EPSS estimates a 0.96% chance of exploitation in the next 30 days.
