Summary
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.
Risk Assessment
An attacker can redirect users to malicious sites or use the server to scan internal networks (SSRF).
Recommendation
Upgrade Apache Shiro to version 2.1.1 or 3.0.0-alpha-2, which encrypt the cookie.
Other vulnerabilities in Apache Shiro
See all- CVE-2016-6802High
Apache Shiro before 1.3.2 allows attackers to bypass intended servlet filters and gain access by leveraging use of a non-root servlet context path.
- 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-2026-43828Medium
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.
Original NVD description (English source)
With valid login credentials, URL Redirection to Untrusted Site ('Open Redirect'), Server-Side Request Forgery (SSRF) vulnerability in Apache Shiro. This issue affects Apache Shiro from 2.0-alpha to 2.1.0, and 3.0.0-alpha-1, only when using shiro-jakarta-ee integration module. Users are recommended to upgrade to version 2.1.1, or 3.0.0-alpha-2 or later, which fixes the issue by encrypting the cookie. After successful login, Jakarta EE integration module uses shiroSavedRequest cookie to redirect to a particular web page after login. This cookie was not validated, and can be forged to send a HTTP GET request from the server itself to an arbitrary URL from the cookie.
