CVE-2026-25674

An issue was discovered in 6.0 before 6.0.3, 5.2 before 5.2.12, and 4.2 before 4.2.29. Race condition in file-system storage and file-based cache backends in Django allows an attacker to cause file system objects to be created with incorrect permissions via concurrent requests, where one thread's temporary `umask` change affects other threads in multi-threaded environments. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Tarek Nakkouch for reporting this issue.

Summary
  • (es) Se descubrió un problema en 6.0 anterior a 6.0.3, 5.2 anterior a 5.2.12 y 4.2 anterior a 4.2.29. Una condición de carrera en el almacenamiento del sistema de archivos y los backends de caché basados en archivos en Django permite a un atacante provocar que los objetos del sistema de archivos se creen con permisos incorrectos a través de solicitudes concurrentes, donde el cambio temporal de 'umask' de un hilo afecta a otros hilos en entornos multihilo. Series de Django anteriores y no compatibles (como 5.0.x, 4.1.x y 3.2.x) no fueron evaluadas y también pueden verse afectadas. Django desea agradecer a Tarek Nakkouch por informar sobre este problema.
