CVE-2021-45116
Due to leveraging the Django Template Language's variable resolution logic, the dictsort template filter was potentially vulnerable to information disclosure, or an unintended method call, if passed a suitably crafted key.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.85%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
