Last modified

CVE-2024-40896 is a critical-severity vulnerability rated 9.1/10 on the CVSS scale. In libxml2 2.11 before 2.11.9, 2.12 before 2.12.9, and 2.13 before 2.13.3, the SAX parser can produce events for external entities even if custom SAX handlers try to override entity content (by setting "checked"). This makes classic XXE attacks possible.. EPSS estimates a 1.19% chance of exploitation in the next 30 days.
