Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS : Django vulnerabilities (USN-8232-1)

medium Nessus Plugin ID 312650

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8232-1 advisory.

 It was discovered that Django did not vary cached response headers on cookies when sessions were not modified while SESSION_SAVE_EVERY_REQUEST was enabled. A remote attacker could possibly use this issue to steal a user's session. (CVE-2026-35192)

 Kyle Agronick and Jacob Walls discovered that Django incorrectly handled ASGI requests with missing or understated Content-Length header values. A remote attacker could possibly use this issue to cause Django to use excessive resources, leading to a denial of service. (CVE-2026-5766)

 Ahmad Sadeddin discovered that Django UpdateCacheMiddleware incorrectly cached requests where the Vary header contained an asterisk. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2026-6907)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected python3-django package.
