Package	Ecosystem	Affected	Fixed in
django	PyPI	<5.2.17 \|\| >=6.0a1, <6.0.8 \|\| >=6.1a1, <6.1.1	5.2.17, 6.0.8, 6.1.1

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Django's GeoDjango component is vulnerable to denial of service in versions 5.2 before 5.2.17 and 6.0 before 6.0.8 (and 6.1 before 6.1.1 per the affected ranges). Parsing deeply nested GEOMETRYCOLLECTION input in WKT, WKB, or hex-encoded WKB causes unbounded recursion and a segmentation fault in the GEOS library, and spatial lookups and GeometryField are also affected. Upgrade Django to 5.2.17, 6.0.8, or 6.1.1. Earlier unsupported series were not evaluated.
