CVE-2023-34478: Apache Shiro before 1.12.0, or 2.0.0-alpha-3, may be susceptible to a path traversal attack when used together with APIs or other web frameworks that route requests based on non-normalized requests.
First published: Mon Jul 24 2023(Updated: )
Apache Shiro could allow a remote authenticated attacker to traverse directories on the system, caused by improper validation of user request. An attacker could send a specially crafted URL request containing "dot dot" sequences (/../) to view arbitrary files on the system.
