CVE-2026-8643 pip can extract console_scripts and gui_scripts outside installation directory
PublishedMediumCVSS 4.1pip would treat console_scripts and gui_scripts as paths instead of file names without sanitizing the resolved absolute path to the installation directory, leading to entry points being installed outside the installation directory.

CVE-2026-44431 urllib3: Sensitive headers forwarded across origins in proxied low-level redirects
PublishedHighCVSS 8.2urllib3 is an HTTP client library for Python. From 1.23 to before 2.7.0, cross-origin redirects followed from the low-level API via ProxyManager.connection_from_url().urlopen(..., assert_same_host=False) still forward these sensitive headers. This vulnerability is fixed in 2.7.0.

CVE-2026-44432 urllib3: Decompression-bomb safeguards bypassed in parts of the streaming API
PublishedHighCVSS 8.9urllib3 is an HTTP client library for Python. From 2.6.0 to before 2.7.0, urllib3 could decompress the whole response instead of the requested portion (1) during the second HTTPResponse.read(amt=N) call when the response was decompressed using the official Brotli library or (2) w...

HighCVSS 7.5
The msgpack decoder fails to properly validate the input buffer length when processing truncated fixext data (format codes 0xd4-0xd8). This can lead to an out-of-bounds read and a runtime panic, allowing a denial of service attack.

CVE-2026-25645 Requests has Insecure Temp File Reuse in its extract_zipped_paths() utility function
PublishedMediumCVSS 5.5Requests is a HTTP library. Prior to version 2.33.0, the requests.utils.extract_zipped_paths() utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validat...
