Medium [CVE-2026-40966] In Spring AI, an attacker
In Spring AI, an attacker can bypass conversation isolation and exfiltrate sensitive memory from other users’ chat histories, including secrets and credentials, by injecting filter logic through conversationId. Only applications that use VectorStoreChatMemoryAdvisor and pass user-supplied input as a conversationId are affected.

The raw message of every server-side AuthenticationException is returned to the unauthenticated remote caller in the gRPC status description. This allows an attacker to obtain information about the authentication failure, which may be useful for further attacks.
Medium [CVE-2026-40971] When configured to use an SSL bundle, Spring Boot's RabbitMQ auto-configuration does not perform hostname verification
When configured to use an SSL bundle, Spring Boot's RabbitMQ auto-configuration does not perform hostname verification when connecting to the RabbitMQ broker. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14) per vendor advisory.
Medium [CVE-2026-40970] When configured to use an SSL bundle, Spring Boot's Elasticsearch auto-configuration does not perform hostname verification

High [CVE-2026-22754] ervlet Path Not Correctly Included in Path Matching of XML Authorization Rules
Vulnerability in Spring Spring Security. If an application uses 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.
High [CVE-2026-22753] Spring Security: Vulnerability in Spring Spring Security.
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.
Medium [CVE-2026-22748] Spring Security: Vulnerability in Spring Spring Security.
Vulnerability in Spring Spring Security. When an application configures JWT decoding with NimbusJwtDecoder or NimbusReactiveJwtDecoder, it must configure an OAuth2TokenValidator 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.
Medium [CVE-2026-22747] Unauthorized User Impersonation when Using X.509 Client Certificates
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.
Low [CVE-2026-22746] Spring Security: Vulnerability in Spring Spring Security.
Vulnerability in Spring Spring Security. If an application is using the UserDetails#isEnabled, #isAccountNonExpired, or #isAccountNonLocked user attributes, to enable, expire, or lock users, then DaoAuthenticationProvider's timing attack defense can be bypassed for users who are disabled, expired, or locked. This issue affects Spring Security: from 5.7.0 through 5.7.22, from 5.8.0 through 5.8.24, from 6.3.0 through 6.3.15, from 6.5.0 through 6.5.9, from 7.0.0 through 7.0.4.
Medium [CVE-2026-22751] Spring Security: Vulnerability in Spring Spring Security.
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.
High [CVE-2026-22734] Cloud Foundry UUA is vulnerable to a bypass
Cloud Foundry UUA is vulnerable to a bypass that allows an attacker to obtain a token for any user and gain access to UAA-protected systems. This vulnerability exists when SAML 2.0 bearer assertions are enabled for a client, as the UAA accepts SAML 2.0 bearer assertions that are neither signed nor encrypted. This issue affects UUA from v77.30.0 to v78.7.0 (inclusive) and it affects CF Deployment from v48.7.0 to v54.14.0 (inclusive).

When configuring SSL bundles in Spring Cloud Gateway by using the configuration property spring.ssl.bundle, the configuration was silently ignored and the default SSL configuration was used instead. Note: The 4.2.x branch is no longer under open source support. If you are using Spring Cloud Gateway 4.2.0 and are not an enterprise customer, you can upgrade to any Spring Cloud Gateway 4.2.x release newer than 4.2.0 available on Maven Centeral. Ideally if you are not an enterprise customer, you should be upgrading to 5.0.2 or 5.1.1 which are the current supported open source releases.
Critical [CVE-2026-22738] In Spring AI, a SpEL injection vulnerability exists in SimpleVectorStore
In Spring AI, a SpEL injection vulnerability exists in SimpleVectorStore when a user-supplied value is used as a filter expression key. A malicious actor could exploit this to execute arbitrary code.
