Description
An issue was discovered in Django 6.1 before 6.1.2, 6.0 before 6.0.9, and 5.2 before 5.2.18. An incomplete fix for CVE-2026-15307 in Django spatial lookups allows an attacker who can supply `bytes` values to cause the Django process to make network requests via a crafted VRT document referencing an external raster source. Earlier, unsupported Django series (such as 5.1.x, 5.0.x, and 4.2.x) were not evaluated and may also be affected. Django would like to thank sicksec for reporting this issue.
