Predictable Temp Directory in Artemis Auto-configuration

Spring Boot's ArtemisEmbeddedConfigurationFactory uses a fixed, static path for the embedded Artemis message broker's data directory when no explicit path is configured. A local attacker on the same host can pre-create this predictable directory or place a symlink before the application starts. Affected versions: Spring Boot 4.0.0 through 4.0.6; 3.5.0 through 3.5.14; 3.4.0 through 3.4.16; 3.3.0 through 3.3.19; 2.7.0 through 2.7.33.

Mail Auto-Configuration Does Not Enable SSL Hostname Verification

Spring Boot's Mail auto-configuration does not enable hostname verification. Applications that set the relevant JavaMail property, such as spring.mail.properties.mail.smtp.ssl.checkserveridentity=true, are not affected. Affected versions: Spring Boot 4.0.0 through 4.0.6; 3.5.0 through 3.5.14; 3.4.0 through 3.4.16.

Values produced by ${random.value} are not suitable for use as secrets. ${random.uuid} is not affected. ${random.int} and ${random.long} should never be used for secrets as they are numeric values with a predictable range. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); random value property source / weak PRNG for secrets. Versions that are no longer supported are also affected per vendor advisory.

Spring Boot: Spring Boot: Missing hostname verification in Elasticsearch auto-configuration allows information disclosure

When configured to use an SSL bundle, Spring Boot's Elasticsearch auto-configuration does not perform hostname verification when connecting to the Elasticsearch server. Affected: Spring Boot 4.0.0–4.0.5; upgrade to 4.0.6 or later per vendor advisory.

Spring Boot: Spring Boot: Information disclosure and data tampering via missing 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.

Versions that are no longer supported are also affected per vendor advisory.

Spring Boot: Spring Boot: Remote code execution via timing attack in DevTools remote secret comparison

An attacker on the same network as the remote application may be able to utilize a timing attack to discover information about the remote secret. In extreme circumstances this could result in the attacker determining the secret and uploading changed classes, thereby achieving remote code execution in the remote application. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); DevTools remote secret comparison. Versions that are no longer supported are also affected per vendor advisory.

Spring Boot: Spring Boot: Arbitrary Code Execution and Session Hijacking via predictable temporary directory

A local attacker on the same host as the application may be able to take control of the directory used by `ApplicationTemp`. When `server.servlet.session.persistent` is set to `true` and the attack persists across application restarts, this may allow the attacker to read session information and hijack authenticated users or deploy a gadget chain and execute code as the application's user. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); predictable temp directory / `ApplicationTemp` ownership verification. Versions that are no longer supported are also affected per vendor advisory.

Spring Boot: Spring Boot: Security bypass due to ineffective default web security

In certain circumstances, Spring Boot's default web security is ineffective allowing unauthorized access to all endpoints. For an application to be vulnerable, it must: be a servlet-based web application; have no Spring Security configuration of its own and rely on the default web security filter chain; depend on spring-boot-actuator-autoconfigure; not depend on spring-boot-health. If any of the above does not apply, the application is not vulnerable. Affected: Spring Boot 4.0.0–4.0.5; upgrade to 4.0.6 or later per vendor advisory.

Spring Boot: Spring Boot: Local file corruption via PID file manipulation

When an application is configured to use `ApplicationPidFileWriter`, a local attacker with write access to the PID file's location can corrupt one file on the host each time the application is started. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); PID file / symlink behavior (`ApplicationPidFileWriter`). Versions that are no longer supported are also affected per vendor advisory.

Authentication Bypass under Actuator CloudFoundry endpoints

Spring Boot applications with Actuator can be vulnerable to an "Authentication Bypass" vulnerability when an application endpoint that requires authentication is declared under the path used by the CloudFoundry Actuator endpoints. This issue affects Spring Security: from 4.0.0 through 4.0.3, from 3.5.0 through 3.5.11, from 3.4.0 through 3.4.14, from 3.3.0 through 3.3.17, from 2.7.0 through 2.7.31.

Authentication Bypass under Actuator Health groups paths

Spring Boot applications with Actuator can be vulnerable to an "Authentication Bypass" vulnerability when an application endpoint that requires authentication is declared under a specific path, already configured for a Health Group additional path. This issue affects Spring Boot: from 4.0 before 4.0.3, from 3.5 before 3.5.11, from 3.4 before 3.4.15. This CVE is similar but not equivalent to CVE-2026-22733, as the conditions for exploit and vulnerable versions are different.

spring-boot: Security Bypass With Wildcard Pattern Matching on Cloud Foundry

In Spring Boot versions 3.0.0 - 3.0.5, 2.7.0 - 2.7.10, and older unsupported versions, an application that is deployed to Cloud Foundry could be susceptible to a security bypass. Users of affected versions should apply the following mitigation: 3.0.x users should upgrade to 3.0.6+. 2.7.x users should upgrade to 2.7.11+. Users of older, unsupported versions should upgrade to 3.0.6+ or 2.7.11+.

Spring Tools 4 for Eclipse version 4.16.0 and below as well as VSCode extensions such as Spring Boot Tools, Concourse CI Pipeline Editor, Bosh Editor and Cloudfoundry Manifest YML Support version 1.39.0 and below all use Snakeyaml library for YAML editing support. This library allows for some special syntax in the YAML that under certain circumstances allows for potentially harmful remote code execution by the attacker.

Spring Boot server Web Observations DoS Vulnerability

In Spring Boot versions 2.7.0 - 2.7.17, 3.0.0-3.0.12 and 3.1.0-3.1.5, it is possible for a user to provide specially crafted HTTP requests that may cause a denial-of-service (DoS) condition. Specifically, an application is vulnerable when all of the following are true: * the application uses Spring MVC or Spring WebFlux * org.springframework.boot:spring-boot-actuator is on the classpath

spring-boot: Spring Boot Welcome Page DoS Vulnerability

In Spring Boot versions 3.0.0 - 3.0.6, 2.7.0 - 2.7.11, 2.6.0 - 2.6.14, 2.5.0 - 2.5.14 and older unsupported versions, there is potential for a denial-of-service (DoS) attack if Spring MVC is used together with a reverse proxy cache.

An issue in Dromara SaToken version 1.36.0 and before allows a remote attacker to escalate privileges via a crafted payload to the URL.

Apache Shiro before 1.11.0, when used with Spring Boot 2.6+, may allow authentication bypass through a specially crafted HTTP request

When using Apache Shiro before 1.11.0 together with Spring Boot 2.6+, a specially crafted HTTP request may cause an authentication bypass. The authentication bypass occurs when Shiro and Spring Boot are using different pattern-matching techniques. Both Shiro and Spring Boot < 2.6 default to Ant style pattern matching. Mitigation: Update to Apache Shiro 1.11.0, or set the following Spring Boot configuration value: `spring.mvc.pathmatch.matching-strategy = ant_path_matcher`

spring-boot versions prior to version v2.2.11.RELEASE was vulnerable to temporary directory hijacking. This vulnerability impacted the org.springframework.boot.web.server.AbstractConfigurableWebServerFactory.createTempDir method. NOTE: This vulnerability only affects products and/or versions that are no longer supported by the maintainer
