CVE‑2020‑13933 Security Issue
The patch for CVE‑2020‑11989 (a June 2020 vulnerability) introduced a flaw: due to differences between Shiro and Spring in URL handling, authentication requests could be processed incorrectly, leaving an authentication bypass that allows remote attackers to send crafted HTTP requests and gain unauthorized access.
