Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - urllib3 is an HTTP client library for Python. From 1.26.0 until 2.8.0, the proxy_ssl_context,
 proxy_assert_hostname, proxy_assert_fingerprint, ssl_context, cert_reqs, verify_mode,
 use_forwarding_for_https=True, and CERT_NONE configuration paths fail to remain separated because target-
 server TLS settings are incorrectly applied to the HTTPS proxy connection. The trigger is that an
 application uses an HTTPS proxy and configures target-server TLS settings that must remain separate from
 the proxy TLS handshake, including HTTPS forwarding with target-specific identity or credentials. Applying
 cert_reqs=CERT_NONE can overwrite proxy_ssl_context.verify_mode in place, and the mutation persists so
 later connections reusing the same context may connect to the HTTPS proxy without certificate
 verification. The attack mechanism is that an attacker intercepts and impersonates the HTTPS proxy after
 the effective proxy policy accepts the attacker's certificate. The impact is that the attacker can observe
 or modify forwarded traffic or receive a target TLS client certificate, while CONNECT tunneling still
 preserves the separate end-to-end target TLS connection. This issue is fixed in version 2.8.0.
 (CVE-2026-97687)

Solution

Update the python-urllib3 library and its related packages to version 1:2.3.0-3+deb13u1+e3 or later.
