CVE ID         : CVE-2023-23934 CVE-2023-25577
Debian Bug     : 1031370

Several vulnerabilities were discovered in python-werkzeug, a collection
of utilities for WSGI applications.

CVE-2023-23934

    It was discovered that Werkzeug did not properly handle the parsing
    of nameless cookies which may allow shadowing of other cookies.

CVE-2023-25577

    It was discovered that Werkzeug could parse unlimited number of
    parts, including file parts, which may result in denial of service.

For the oldstable distribution (bullseye), these problems have been fixed
in version 1.0.1+dfsg1-2+deb11u1.

We recommend that you upgrade your python-werkzeug packages.
