Summary
python-werkzeug vulnerabilities
Details

It was discovered that Werkzeug did not properly handle the parsing of nameless cookies. A remote attacker could possibly use this issue to shadow other cookies. (CVE-2023-23934)

It was discovered that Werkzeug could be made to process unlimited number of multipart form data parts. A remote attacker could possibly use this issue to cause Werkzeug to consume resources, leading to a denial of service. (CVE-2023-25577)
