installed that are affected by multiple vulnerabilities as referenced in the USN-8848-1 advisory.

    Bence Nagy discovered that GeoDjango in Django incorrectly handled spatial lookups when processing
    untrusted input. A remote attacker could possibly use this issue to make outbound network requests, write
    arbitrary files, or execute arbitrary code. This issue was only addressed in Ubuntu 22.04 LTS, Ubuntu
    24.04 LTS and Ubuntu 26.04 LTS. (CVE-2026-15307)

    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)

    Ahmed Badawe discovered that Django did not properly parse Cache-Control response directives case-
    insensitively under certain circumstances. A remote attacker could possibly use this issue to view
    sensitive information from responses that were incorrectly cached. This issue only affected

    Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-8404)

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