Advisory Released Date: 2026-01-07
Advisory Updated Date: 2026-01-07
Severity:
Medium
Issue Overview:
When building nested elements using xml.dom.minidom methods such as appendChild() that have a dependency on _clear_id_cache() the algorithm is quadratic. Availability can be impacted when building excessively nested documents. (CVE-2025-12084)
When loading a plist file, the plistlib module reads data in size specified by the file itself, meaning a malicious file can cause OOM and DoS issues (CVE-2025-13837)
