An application using Spring Security's WebAuthn support may be vulnerable to user verification bypass when using a distributed HTTP session store. Spring Security 7.1.0 Spring Security 7.0.0 - 7.0.6 Spring Security 6.5.0 - 6.5.11 Spring Security 6.4.0 - 6.4.18

Spring Security Authorization Server's default consent page renders user-controlled values without HTML entity encoding. Spring Security 7.1.0 Spring Security 7.0.0 - 7.0.6

An application using spring-security-saml2-service-provider and the REDIRECT binding for SAML 2.0 Login or Logout may be vulnerable to a denial of service by way of an unbounded writer that inflates the compressed SAML payload into memory.

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.

An attacker with write permissions to the database table managed by JdbcAssertingPartyMetadataRepository (saml2assertingpartymetadata) may be able to store malicious serialized payloads in the columns containing the collection of verification or encryption credentials (verificationcredentials and encryptioncredentials, respectively).

Affected versions: Spring Security 7.0.0 through 7.0.5.

An attacker able to influence values in RelyingPartyRegistration may be able to run arbitrary code on HTML forms generated by Spring Security filters.

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.

Vulnerability in Spring Spring Security. If an application uses <sec:intercept-url servlet-path="/servlet-path" pattern="/endpoint/"/> to define the servlet path for computing a path matcher, then the servlet path is not included and the related authorization rules are not exercised. This can lead to an authorization bypass.This issue affects Spring Security: from 7.0.0 through 7.0.4.

Vulnerability in Spring Spring Security. SubjectX500PrincipalExtractor does not correctly handle certain malformed X.509 certificate CN values, which can lead to reading the wrong value for the username. In a carefully crafted certificate, this can lead to an attacker impersonating another user. This issue affects Spring Security: from 7.0.0 through 7.0.4.

Vulnerability in Spring Spring Security. If an application is using securityMatchers(String) and a PathPatternRequestMatcher.Builder bean to prepend a servlet path, matching requests to that filter chain may fail and its related security components will not be exercised as intended by the application. This can lead to the authentication, authorization, and other security controls being rendered inactive on intended requests.This issue affects Spring Security: from 7.0.0 through 7.0.4.
