libexpat before 2.8.2 does not consider XML_TOK_DATA_CHARS in doCdataSection and thus lacks handler call depth tracking for various calls from within handlers in cases of a policy violation. Thus, a use-after-free can occur. NOTE: this issue exists because of an incomplete fix for CVE-2026-50219.
A flaw was found in libexpat. This vulnerability, present in versions before 2.8.2, stems from improper handling of XML CDATA sections, where the library fails to adequately track the depth of handler calls. This can result in a 'use-after-free' error, a type of memory corruption that could allow an attacker to crash the application or potentially gain unauthorized control.
