Exploitation Probability (EPSS)

Low risk
0.35%

29th percentile - higher than 29% of all known CVEs

Summary

roxmltree through 0.21.1 performs quadratic-time attribute and namespace validation during XML parsing without limits on attribute count. Attackers can craft XML documents with tens of thousands of attributes on a single element to consume excessive CPU time and cause denial of service.

Risk Assessment

A malicious XML document can trigger prolonged processing and block the XML-parsing application, causing denial of service. The risk affects services processing untrusted XML data.

Recommendation

Upgrade roxmltree to a version later than 0.21.1, or enforce attribute-count and parsing-time limits in the application.
