Apache Shiro before 1.2.5, when a cipher key has not been configured for the "remember me" feature, allows remote attackers to execute arbitrary code or bypass intended access restrictions via an. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Actively exploited in the wild (cisa kev) and public exploit code available.
Server-Side Request Forgery (SSRF) in Apache Shiro's Jakarta EE integration module (shiro-jakata-ee) enables a low-privileged authenticated user to steer server-initiated POST requests to an attacker-controlled host and transmit attacker-controlled data. Versions 2.0.0-alpha-0 through 3.0.0 of the shiro-jakata-ee artifact are affected, but only when the Jakarta EE integration module is deployed - the 1.x line and non-Jakarta-EE deployments are not vulnerable. No public exploit has been identified at time of analysis, and vendor-released patch 3.0.1 is available as of 2026-08-24.
