Technical details
The `django.http.HttpRequest.get_signed_cookie` function in Django uses a non-injective salt derivation method by concatenating the cookie name and the salt argument. This flaw allows for salt namespace collisions where distinct `(name, salt)` pairs produce the same concatenated string. A remote attacker with low privileges can exploit this to use a signed cookie in a context different from the one where it was originally signed. The issue affects Django versions before 5.2.15 and 6.0.x before 6.0.6; older unsupported versions may also be impacted. Patches have been released in versions 5.2.15 and 6.0.6.
