A flaw was found in Django's GIS support. Spatial lookups accepted raster values supplied as raw bytes without requiring them to first be wrapped in django.contrib.gis.gdal.GDALRaster. Because such values are opened through GDAL's in-memory virtual filesystem, a crafted value could contain a VRT document referencing an external raster source, causing GDAL to issue outbound network requests as the Django process user while preparing the lookup. An application that passes attacker-controlled bytes directly into a spatial lookup could therefore be induced to make server-side requests to attacker-chosen hosts. This issue was overlooked in the fix for CVE-2026-15307. It is a backward-incompatible fix: raster values provided as bytes must now be explicitly wrapped in GDALRaster before use in spatial lookups, though byte values representing valid hexadecimal geometries remain accepted.
