CVE-2026-35193
Description
A flaw was found in Django. This vulnerability allows a remote attacker to read private cached responses. This occurs because the UpdateCacheMiddleware in Django does not correctly add the Authorization header to the Vary response header for requests that include an Authorization header but lack Cache-Control: public. Consequently, unauthenticated requests to the same URL can access sensitive cached information.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
