# CVE-2026-111211: Potential log injection via unescaped geometry form values

Status: published. Published: 2026-11-03. Updated: 2026-11-03.

An issue was discovered in Django 6.1 before 6.1.3, 6.0 before 6.0.10, and 5.2 before 5.2.19.
`django.contrib.gis.forms.widgets.BaseGeometryWidget.deserialize()`, used by `django.contrib.gis.forms.GeometryField`, does not escape invalid submitted values before logging them, which allows remote attackers to inject or forge log entries via a crafted geometry value.
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 Aaron chen for reporting this issue.
