Other vulnerabilities in Apache Shiro
See all- CVE-2014-0074High
Apache Shiro 1.x before 1.2.3, when using an LDAP server with unauthenticated bind enabled, allows remote attackers to bypass authentication via an empty username or password.
- CVE-2026-49268Critical
A remote attacker can inject LDAP special characters into the Distinguished Name (DN) construction in DefaultLdapRealm class. User-supplied username input is directly concatenated into the LDAP DN template without any escaping, allowing manipulation of the DN structure used for LDAP bind authentication.
- CVE-2023-34478Critical
Apache Shiro, before 1.12.0 or 2.0.0-alpha-3, may be susceptible to a path traversal attack that results in an authentication bypass when used together with APIs or other web frameworks that route requests based on non-normalized requests.
- CVE-2026-48589Medium
The Jakarta EE module in Apache Shiro (versions 2.0-alpha to 2.2.0 and 3.0.0-alpha-1) uses the HTTP Referer header for redirect after login. Insufficient validation of this client-controlled header could allow an attacker to influence the redirect target.
- CVE-2026-44598Medium
Apache Shiro versions 2.0-alpha to 2.1.0 and 3.0.0-alpha-1, when using the shiro-jakarta-ee module, are vulnerable to Open Redirect and SSRF. After login, the shiroSavedRequest cookie was not validated, allowing redirect to arbitrary URLs and server-side GET requests.
- CVE-2026-43828Medium
Default configurations of Apache Shiro send sensitive cookies (JSESSIONID and rememberMe) in HTTPS sessions without the 'Secure' attribute. Affects versions 1.0 to 2.1.0 and 3.0.0-alpha-1. Fixed in 2.1.1 and 3.0.0-alpha-2.
- CVE-2026-43827Medium
Default configurations of Apache Shiro have a session fixation vulnerability. Affects versions 1.0 to 2.1.0 and 3.0.0-alpha-1. In affected versions, when a session already exists, it is not invalidated upon successful login, nor is a new session generated with a new ID. Users are recommended to upgrade to version 2.1.1 or 3.0.0-alpha-2.
- CVE-2026-23903Medium
Vulnerability in Apache Shiro allows authentication bypass by varying the case of filenames in requests for static files. If static files are served from a case-insensitive filesystem (e.g., default macOS), an attacker can access files not covered by Shiro filters. Affects versions before 2.0.7.
