CVE-2026-6873
Fixed in a distro release EPSS <1%CVSS 3.1
An issue was discovered in Django 6.0 before 6.0.6 and 5.2 before 5.2.15. `django.http.HttpRequest.get_signed_cookie` in Django uses a non-injective salt derivation (concatenating the cookie name and salt argument), which allows a remote attacker to use a cookie in a context different from the one where it was signed, via distinct `(name, salt)` pairs that produce the same concatenation. 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 Peng Zhou for reporting this issue.
