Description
This security bulletin contains information about 2 vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2026-44431)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to exposure of sensitive information in ProxyManager.connection_from_url().urlopen() when following cross-origin redirects with assert_same_host=False through a proxy. A remote attacker can trigger a cross-origin redirect to disclose sensitive information.
Sensitive headers such as Authorization, Cookie, and Proxy-Authorization may be forwarded across origins in this low-level redirect flow.
2) Improper handling of highly compressed data (CVE-ID: CVE-2026-44432)
CWE-ID: CWE-409 - Improper Handling of Highly Compressed Data (Data Amplification)
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to improper handling of highly compressed data in the urllib3 streaming API when processing compressed HTTP responses from untrusted sources. A remote attacker can send a highly compressed response to cause a denial of service.
Exploitation requires either incremental reads of a Brotli-encoded response with at least two read or stream calls while using the official Brotli library, or calling HTTPResponse.drain_conn() after decompression has already started.
