1) Inefficient algorithmic complexity (CVE-ID: CVE-2025-12084)

The vulnerability allows a remote attacker to perform a denial of service attack.

The vulnerability exists due to usage of a quadratic algorithm when building nested elements using xml.dom.minidom methods such as appendChild() that have a dependency on _clear_id_cache(). A remote attacker can force the application to create excessively nested documents, leading to a denial of service condition. 


2) Resource exhaustion (CVE-ID: CVE-2025-13836)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when reading HTTP responses in Lib/http/client.py. A remote attacker can trigger memory exhaustion and perform a denial of service (DoS) attack.


3) Resource exhaustion (CVE-ID: CVE-2025-13837)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources in Lib/plistlib.py. A remote attacker can pass a specially crafted file to the application, trigger memory exhaustion and perform a denial of service (DoS) attack.
