In Spring Security, versions 5.7.x prior to 5.7.8, versions 5.8.x prior to 5.8.3, and versions 6.0.x prior to 6.0.3, the logout support does not properly clean the security context if using serialized versions. Additionally, it is not possible to explicitly save an empty security context to the HttpSessionSecurityContextRepository. This vulnerability can keep users authenticated even after they performed logout. Users of affected versions should apply the following mitigation. 5.7.x users should upgrade to 5.7.8. 5.8.x users should upgrade to 5.8.3. 6.0.x users should upgrade to 6.0.3.

Pivotal Spring Security and Spring Framework could allow a remote attacker to bypass security restrictions, caused by the failure to consider URL path parameters when processing security constraints. By adding a URL path parameter with special encodings, an attacker could exploit this vulnerability to bypass access restrictions and gain access to the server and obtain sensitive information.

Spring Security Authorization Server's authorization endpoint performs insufficient validation of the requesturi parameter. An attacker can craft a malicious authorization request containing an invalid requesturi and an arbitrary, unvalidated redirecturi, which can lead to an Open Redirect vulnerability.

Affected versions: Spring Security 7.0.0 through 7.0.5. Spring Authorization Server 1.5.0 through 1.5.7.

Since Spring Security SAML decrypts SAML Responses as well as elements of SAML LogoutRequests and LogoutResponses without requiring a valid signature, attackers may be able to craft these SAML payloads and use the Service Provider as a decryption oracle.

Affected versions: Spring Security 5.7.0 through 5.7.23; 5.8.0 through 5.8.25; 6.3.0 through 6.3.16; 6.4.0 through 6.4.16; 6.5.0 through 6.5.10; 7.0.0 through 7.0.5.

Spring Security's CookieRequestCache and CookieServerRequestCache store the pre-authentication request URL in a browser cookie so that users can be redirected back to their intended destination after a successful login. In affected versions, the full absolute URL is stored in the cookie and is used without validation as the post-login redirect target.

Affected versions: Spring Security 5.7.0 through 5.7.23; 5.8.0 through 5.8.25; 6.3.0 through 6.3.16; 6.4.0 through 6.4.16; 6.5.0 through 6.5.10; 7.0.0 through 7.0.5.

Spring Framework 3.0.0 through 3.0.5, Spring Security 3.0.0 through 3.0.5 and 2.0.0 through 2.0.6, and possibly other versions deserialize objects from untrusted sources, which allows remote attackers to bypass intended security restrictions and execute untrusted code by (1) serializing a java.lang.Proxy instance and using InvocationHandler, or (2) accessing internal AOP interfaces, as demonstrated using deserialization of a DefaultListableBeanFactory instance to execute arbitrary commands via the java.lang.Runtime class.

Vulnerability in Spring Spring Security. When an application configures JWT decoding with NimbusJwtDecoder  or NimbusReactiveJwtDecoder, it must configure an OAuth2TokenValidator<Jwt> separately, for example by calling setJwtValidator.This issue affects Spring Security: from 6.3.0 through 6.3.14, from 6.4.0 through 6.4.14, from 6.5.0 through 6.5.9, from 7.0.0 through 7.0.4.

Vulnerability in Spring Spring Security. Applications that explicitly configure One-Time Token login with JdbcOneTimeTokenService are vulnerable to a Time-of-check Time-of-use (TOCTOU) race condition. This issue affects Spring Security: from 6.4.0 through 6.4.15, from 6.5.0 through 6.5.9, from 7.0.0 through 7.0.4.
