Description

This security bulletin contains information about 1 vulnerability.


1) Open redirect (CVE-ID: CVE-2026-54770)

CWE-ID: CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')

CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows an unauthenticated remote attacker to redirect users from a trusted WebOb application to an attacker-controlled host.

The vulnerability exists due to inconsistent Location header validation and URL normalization on Python 3.10+, where leading spaces or C0 control characters conceal an external redirect destination from validation. An unauthenticated remote attacker can supply a crafted destination when the application accepts attacker-influenced redirect targets, causing off-site navigation when a user follows the redirect.
