Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C...

CVE-2026-6879

A flaw was found in Python's xml.etree.ElementPath component. This vulnerability can lead to a denial of service DoS when processing specially crafted XML documents. Specifically, certain XPath index predicates used with functions like Element.findall and Element.iterfind can cause the processing...

AZL-94299 CVE-2026-6879 affecting package python3 for versions less than 3.12.9-14

Element.findall and fully-consumed Element.iterfind exhibit On^2 time complexity when using XPath index predicates e.g. 1, last, last-N on XML documents with many same-tag siblings. Element.find is only affected when the first match is near the end of the sibling list, such as with last or...
