Spring gRPC AuthenticationException message reflected to remote client

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. Affected versions: Spring gRPC: 1.0.0 - 1.0.2 (fixed in 1.0.3). Older, unsupported versions are also affected.

Spring Cloud Gateway Server Forwards Headers from Untrusted Proxies in certain situations

Spring Cloud Gateway Server forwards the X-Forwarded-For and Forwarded headers from untrusted proxies in certain configuration scenarios. This affects both the WebMVC and WebFlux Gateway Servers. Affected versions: Spring Cloud Gateway 3.1.x (fix 3.1.13). Spring Cloud Gateway 4.1.x (fix 4.1.13). Spring Cloud Gateway 4.2.x (fix 4.2.9). Spring Cloud Gateway 4.3.x (fix 4.3.5). Spring Cloud Gateway 5.0.x (fix 5.0.2).

In Spring AMQP sequential correlation IDs enable reply poisoning on fixed reply queues

Correlation IDs for replies in the RabbitTemplate.sendAndReceive() with the fixed reply queue are predictable due to internal simple counter. Affected versions: Spring AMQP 4.0.0 through 4.0.3; 3.2.0 through 3.2.10; 3.1.0 through 3.1.15; 2.4.0 through 2.4.17.

Cleartext Storage of Spring Boot DevTools Remote Secret in Eclipse Launch Configurations

Spring Tools for Eclipse stores the Spring Boot DevTools remote secret (spring.devtools.remote.secret) as a plain string attribute on the "Spring Boot DevTools Client" launch configuration. Eclipse persists launch configuration attributes as cleartext XML, either to workspace metadata or, if the user marks the configuration as a shared file, directly into the project tree where it can be committed to version control. This secret is the sole credential protecting the DevTools remote restart/reload endpoint, which accepts and executes arbitrary class bytes on the target application. Anyone able to read the .launch file (via filesystem access, a workspace backup, or a shared VCS repository) can extract the secret and use it to achieve remote code execution against the associated Spring Boot application. Affected Spring Products and Versions: Spring Tools for Eclipse: 5.2.0 and earlier

Spring Tools Docker integration publishes unauthenticated debug (JDWP) and JMX ports on all network interfaces

The Boot Dashboard Docker integration in Spring Tools publishes container control ports on all of the host's network interfaces (0.0.0.0) rather than restricting them to loopback. Affected Spring Products and Versions: Spring Tools for Eclipse: 5.2.0 and earlier

Spring Boot DevTools remote secret generated with a non-cryptographic PRNG

When enabling Spring Boot DevTools support for a remote application target (for example a Docker container or Cloud Foundry app) from the Spring Tools Boot Dashboard, Spring Tools generates a shared secret that authenticates DevTools remote-restart uploads to the deployed application. This secret was generated using a non-cryptographic pseudo-random number generator rather than a cryptographically secure source of randomness. Affected Spring Products and Versions: Spring Tools for Eclipse: 5.2.0 and earlier

Cross-Site Scripting in Eclipse Spring Boot Starter Wizard Dependency Tooltips

Spring Tools for Eclipse renders Spring Boot starter wizard dependency tooltips in a native embedded browser (SWT Browser) with JavaScript enabled. Using untrusted and compromised Initializr endpoints for the Spring Boot starter wizard can result in arbitrary script execution inside the embedded browser when a developer hovers a dependency checkbox in the New Spring Starter Project wizard. Impact is limited to in-IDE UI spoofing and outbound network beaconing rather than full code execution. Affected Spring Products and Versions: Spring Tools for Eclipse: 5.2.0 and earlier

Spring Security DPoPProofJwtDecoderFactory vulnerable to DPoP Proof Replay

Authentication Bypass by Capture-replay vulnerability in Spring Spring Security allows Spring Security's DPoPProofJwtDecoderFactory contains a cache-based replay attack vulnerability. The internal cache storing JWT ID claims has a strict size limit, allowing attackers to evict legitimate entries by flooding the server with dummy requests, then replay intercepted valid DPoP proofs. This issue affects Spring Security: 7.1.0, from 7.0.0 through 7.0.6, and from 6.5.0 through 6.5.11.

Potential for logging sensitive data in Spring Cloud Stream

Potential for logging sensitive data in Spring Cloud Stream. Spring Cloud Stream 5.0.0 - 5.0.2 Spring Cloud Stream 4.3.0 - 4.3.3 Spring Cloud Stream 4.2.0 - 4.2.6

Spring Statemachine's Kryo-based persistence backends (JPA, MongoDB, Redis and ZooKeeper) deserialise persisted state-machine contexts without enforcing a class allowlist (CWE-502, deserialisation of untrusted data), which can lead to remote code execution inside the application JVM. Affected versions: Spring Statemachine 4.0.0 through 4.0.1 Spring Statemachine 3.2.0 through 3.2.4

Unbounded persistent session allocation via repeated initialize requests

The MCP Streamable HTTP server transport (WebFlux and WebMvc variants) does not place any limit on the number of sessions it retains, and by default does not require clients to be authenticated. As a result, a remote attacker can cause the server to accumulate an unbounded number of sessions over time, gradually exhausting available memory and ultimately causing a Denial of Service that affects all legitimate clients. Affected versions: Spring AI: 2.0.0

Semantic Cache Cross-Tenant Isolation Bypass via SHA-256 Truncation

In Spring AI's Semantic Cache support, the context hash used to isolate cached responses between different system prompts could allow cached responses to be shared across unrelated contexts. Affected versions: Spring AI: 2.0.0

DefaultToolCallingManager Global Resolver Fallback Allows Unadvertised Tool Dispatch via Prompt Injection

In Spring AI's tool calling support, the per-request tool list is advertised to the model as a boundary but is not fully enforced when a tool call is dispatched. Under certain conditions, a tool that was not made available to the current request could be invoked, potentially leading to privilege escalation. Affected versions: Spring AI: 2.0.0 Spring AI: 1.1.0 through 1.1.8 Spring AI: 1.0.0 through 1.0.9

Micrometer HTTP server instrumentations DoS vulnerability

In Micrometer, it is possible for a user to provide specially crafted HTTP requests that may cause a denial-of-service (DoS) condition.

Unsafe Java deserialization in DefaultExecutionContextSerializer without class allowlist

DefaultExecutionContextSerializer, used by default in Spring Batch's JDBC job repository, passes Base64-decoded bytes directly to ObjectInputStream.readObject() without an ObjectInputFilter that restricts types to a trusted class allowlist. Spring Batch 6.0.0 - 6.0.4 Spring Batch 5.2.6 and earlier

Spring Cloud Gateway SSRF and native file access with gRPC

Spring Cloud Gateway JsonToGrpcGatewayFilterFactory allows arbitrary Spring Resource locations for defining the proto descriptor. Spring Cloud Gateway 5.0.0 - 5.0.2 Spring Cloud Gateway 4.3.0 - 4.3.5 Spring Cloud Gateway 4.0.0 - 4.2.9 Spring Cloud Gateway 3.1.13 and earlier

DefaultJmsHeaderMapper copies all JMS user properties into MessageHeaders without excluding framework-significant names

A producer who can publish to a JMS destination consumed by any Spring Integration JMS inbound component can set String JMS properties named replyChannel, errorChannel, or json__TypeId__ which are copied verbatim into the Spring Integration MessageHeaders. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10 Spring Integration 6.4.0 - 6.4.12 Spring Integration 5.5.21 and earlier

Spring Framework Open Redirect in UrlHandlerFilter
