🛡️ USN-8344-1 — python-pip

python-pip vulnerabilities

It was discovered that pip incorrectly handled TLS certificate

verification in session connections. If a session was first used with

certificate verification disabled, subsequent requests to the same host

would also skip verification regardless of the session's current settings.

A remote attacker could possibly use this issue to perform a machine-in-the-middle

attack and expose sensitive information. (CVE-2024-35195)

It was discovered that pip's bundled urllib3 library did not limit the

number of decompression steps when processing HTTP responses. A remote

attacker could possibly use this issue to cause pip to consume excessive resources,

leading to a denial of service. (CVE-2025-66418)

It was discovered that pip's bundled urllib3 library improperly

handled streaming decompression of highly compressed data. A remote

attacker could possibly use this issue to cause pip to consume excessive resources,

leading to a denial of service. (CVE-2025-66471)
