{"id":"DEBIAN-CVE-2026-15830","details":"An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8. GeoDjango's `django.contrib.gis.geos.GEOSGeometry` is subject to a potential denial-of-service when parsing deeply nested `GEOMETRYCOLLECTION` objects supplied as well-known text (WKT), well-known binary (WKB), or hex-encoded WKB, which triggers unbounded recursion and a segmentation fault in the underlying GEOS library. Spatial field lookups and the `django.contrib.gis.forms.GeometryField` form field are also affected. 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 Andrew MacPherson and kimchunbok_ for reporting this issue.","modified":"2026-09-01T16:06:30.585049165Z","published":"2026-08-04T17:16:46.593Z","upstream":["CVE-2026-15830"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-15830"}],"affected":[{"package":{"name":"python-django","ecosystem":"Debian:12","purl":"pkg:deb/debian/python-django?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3:3.2.19-1","3:3.2.19-1+deb12u1","3:3.2.19-1+deb12u1~bpo11+1","3:3.2.19-1+deb12u2","3:3.2.20-1","3:3.2.20-1.1","3:3.2.21-1","3:3.2.25-0+deb12u1","3:3.2.25-0+deb12u2","3:3.2.25-0+deb12u3","3:3.2.25-0+deb12u4","3:4.1-1","3:4.1.1-1","3:4.1.2-1","3:4.1.3-1","3:4.1.4-1","3:4.1.5-1","3:4.2-1","3:4.2.1-1","3:4.2.10-1","3:4.2.11-1","3:4.2.13-1","3:4.2.14-1","3:4.2.15-1","3:4.2.15-1~bpo12+1","3:4.2.16-1","3:4.2.17-1","3:4.2.17-2","3:4.2.18-1","3:4.2.18-1~bpo12+1","3:4.2.19-1","3:4.2.19-1~bpo12+1","3:4.2.2-1","3:4.2.20-1","3:4.2.20-1~bpo12+1","3:4.2.21-1","3:4.2.21-1~bpo12+1","3:4.2.22-1","3:4.2.23-1","3:4.2.24-1","3:4.2.25-1","3:4.2.25-2","3:4.2.26-1","3:4.2.27-1","3:4.2.27-2","3:4.2.28-1","3:4.2.29-1","3:4.2.3-1","3:4.2.30-1","3:4.2.4-1","3:4.2.5-1","3:4.2.5-2","3:4.2.6-1","3:4.2.8-1","3:4.2.9-1","3:4.2~alpha1-1","3:4.2~beta1-1","3:4.2~rc1-1","3:5.0-1","3:5.0.1-1","3:5.0.2-1","3:5.0.3-1","3:5.0.4-1","3:5.0.6-1","3:5.0~alpha1-1","3:5.0~rc1-1","3:5.1-1","3:5.1.1-1","3:5.1.2-1","3:5.1.3-1","3:5.1.4-1","3:5.1.5-1","3:5.1~alpha1-1","3:5.1~beta1-1","3:5.1~rc1-1","3:5.2-1","3:5.2.1-1","3:5.2.13-1","3:5.2.14-1","3:5.2.14-2","3:5.2.15-1","3:5.2.15-2","3:5.2.15-2~bpo13+1","3:5.2.16-1","3:5.2.16-1~bpo13+1","3:5.2.17-1","3:5.2.17-2","3:5.2.2-1","3:5.2.3-1","3:5.2.4-1","3:5.2.5-1","3:5.2.6-1","3:5.2~alpha1-1","3:5.2~beta1-1","3:5.2~rc1-1","3:6.0-1","3:6.0.1-1","3:6.0.2-1","3:6.0.3-1","3:6.0.4-1","3:6.0.5-1","3:6.0.6-1","3:6.0~alpha1-1","3:6.0~beta1-1","3:6.0~rc1-1","3:6.1-1","3:6.1~beta1-1","3:6.1~rc1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-15830.json"}},{"package":{"name":"python-django","ecosystem":"Debian:13","purl":"pkg:deb/debian/python-django?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3:4.2.23-1","3:4.2.24-1","3:4.2.25-1","3:4.2.25-2","3:4.2.26-1","3:4.2.27-0+deb13u1","3:4.2.27-1","3:4.2.27-2","3:4.2.28-0+deb13u1","3:4.2.28-0+deb13u2","3:4.2.28-1","3:4.2.29-1","3:4.2.30-1","3:5.0-1","3:5.0.1-1","3:5.0.2-1","3:5.0.3-1","3:5.0.4-1","3:5.0.6-1","3:5.0~alpha1-1","3:5.0~rc1-1","3:5.1-1","3:5.1.1-1","3:5.1.2-1","3:5.1.3-1","3:5.1.4-1","3:5.1.5-1","3:5.1~alpha1-1","3:5.1~beta1-1","3:5.1~rc1-1","3:5.2-1","3:5.2.1-1","3:5.2.13-1","3:5.2.14-1","3:5.2.14-2","3:5.2.15-1","3:5.2.15-2","3:5.2.15-2~bpo13+1","3:5.2.16-1","3:5.2.16-1~bpo13+1","3:5.2.17-1","3:5.2.17-2","3:5.2.2-1","3:5.2.3-1","3:5.2.4-1","3:5.2.5-1","3:5.2.6-1","3:5.2~alpha1-1","3:5.2~beta1-1","3:5.2~rc1-1","3:6.0-1","3:6.0.1-1","3:6.0.2-1","3:6.0.3-1","3:6.0.4-1","3:6.0.5-1","3:6.0.6-1","3:6.0~alpha1-1","3:6.0~beta1-1","3:6.0~rc1-1","3:6.1-1","3:6.1~beta1-1","3:6.1~rc1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-15830.json"}},{"package":{"name":"python-django","ecosystem":"Debian:14","purl":"pkg:deb/debian/python-django?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3:5.2.17-1"}]}],"versions":["3:4.2.23-1","3:4.2.24-1","3:4.2.25-1","3:4.2.25-2","3:4.2.26-1","3:4.2.27-1","3:4.2.27-2","3:4.2.28-1","3:4.2.29-1","3:4.2.30-1","3:5.0-1","3:5.0.1-1","3:5.0.2-1","3:5.0.3-1","3:5.0.4-1","3:5.0.6-1","3:5.0~alpha1-1","3:5.0~rc1-1","3:5.1-1","3:5.1.1-1","3:5.1.2-1","3:5.1.3-1","3:5.1.4-1","3:5.1.5-1","3:5.1~alpha1-1","3:5.1~beta1-1","3:5.1~rc1-1","3:5.2-1","3:5.2.1-1","3:5.2.13-1","3:5.2.14-1","3:5.2.14-2","3:5.2.15-1","3:5.2.15-2","3:5.2.15-2~bpo13+1","3:5.2.16-1","3:5.2.16-1~bpo13+1","3:5.2.2-1","3:5.2.3-1","3:5.2.4-1","3:5.2.5-1","3:5.2.6-1","3:5.2~alpha1-1","3:5.2~beta1-1","3:5.2~rc1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-15830.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
