Description
This security bulletin contains information about 3 vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2026-15337)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 6.9 [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]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to uncontrolled memory consumption in django.utils.translation.check_for_language() when checking many distinct, very long language codes. A remote attacker can send crafted POST data containing many distinct long language values to cause a denial of service.
The language value reaches this function through the django.views.i18n.set_language() view, which is not active by default, and the memory consumption is bounded by request size and cache entry limits.
2) Uncontrolled Recursion (CVE-ID: CVE-2026-15830)
CWE-ID: CWE-674 - Uncontrolled Recursion
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to improper handling of deeply nested input in GEOSGeometry when parsing deeply nested GEOMETRYCOLLECTION objects. A remote attacker can supply a crafted geometry input to cause a denial of service.
Lookups against spatial fields and the GeometryField form field were also affected. GeoJSON inputs were not affected.
3) Cross-site scripting (CVE-ID: CVE-2026-15920)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]

The vulnerability exists due to improper neutralization of input during web page generation in admin URLField rendering when displaying stored URLField values as clickable links. A remote user can store a URLField value with a dangerous scheme to execute arbitrary script in a user's browser.
The issue affected changelist views and read-only fields rendered through display_for_field.
