CVE-2026-47861

Spring Integration UDP inbound adapter contains a flaw where the adapter sends an acknowledgment (ack) to a host:port parsed from the packet body, even when acknowledge=false is configured. An unauthenticated remote attacker who can send a single UDP packet to the adapter can cause the server to ...

CVE-2026-40987

CVE-2026-40987 affects Spring Integration across multiple tracked branches (7.0.0–7.0.4, 6.5.0–6.5.8, 6.4.0–6.4.11, 6.3.0–6.3.14, 5.5.0–5.5.20). The connected documents describe a vulnerability where a malicious or compromised FTP/SFTP/SMB server can cause the client to write arbitrary files anyw...

CVE-2026-59324

Spring Integration is vulnerable to cross-message header leakage when an IntegrationFlow uses .fluxTransform() with an asynchronous or reordering fluxFunction that emits raw payloads. The root cause is a shared RequestMessageHolder , which causes concurrent requests on the same FluxMessageChannel...

CVE-2026-59321

Spring Integration versions 7.1.0 , 7.0.0–7.0.5 , 6.5.0–6.5.10 , 6.4.0–6.4.12 , and 5.5.21 and earlier are affected by a thread-safety flaw in script-backed channels. A single JSR-223 ScriptEngine instance is shared across all messages without verifying the engine's THREADING capability. When a n...

CVE-2026-47864

Spring Integration 's SerializingHttpMessageConverter deserializes incoming HTTP request bodies using a raw java.io.ObjectInputStream with no class filtering. Any request with Content-Type: application/x-java-serialized-object whose body resolves to a Serializable type is processed directly via r...

CVE-2026-47856

Spring Integration 's JsonToObjectTransformer deserializes JSON messages by resolving the json__TypeId__ message header to a target class via ClassUtils.forName, with no type or package allow-list to constrain the resolved class. This allows an attacker with low privileges to supply an arbitrary ...

CVE-2026-47859

CVE-2026-47859 affects Spring Integration 's RFC6587SyslogDeserializer , the component used by the syslog TCP inbound adapter to decode RFC 6587 / RFC 5424 frames. The root cause is that the deserializer trusts the sender-supplied octet count of an octet-counted frame and allocates a byte array o...

CVE-2026-59307

Spring Integration JdbcMessageStore has a deserialization allow-list bypass. When the store is a Spring-managed bean , calling addAllowedPatterns(...) to restrict deserialization is silently ineffective because setBeanClassLoader (invoked during Spring's bean lifecycle) replaces the deserializer ...

CVE-2026-59322

Spring Integration 's EmbeddedHeadersJsonMessageMapper defaults to an overly permissive header-parsing posture in its constructor. When decodeNativeFormat processes raw byte payloads, it deserializes embedded JSON headers into a plain Map and constructs a GenericMessage with MutableMessageHeaders...

CVE-2026-59311

Spring Integration is vulnerable to a symlink pre-creation attack on its predictable /tmp/ziptransformer work directory. A local unprivileged user on the same host can pre-create that path as a symlink before the application starts, redirecting all Zip/Unzip transformer output into a directory of...

CVE-2026-59292

CVE-2026-59292 affects Spring Integration , where the default file-based PropertiesPersistingMetadataStore persists its state to ${java.io.tmpdir}/spring-integration/metadata-store.properties with world-readable permissions , allowing local users with high privileges to read metadata. The CVSS 3....

CVE-2026-47862

Spring Integration's ZipTransformer component is vulnerable to a path traversal issue when using the default ZipResultType.FILE result type. An attacker who can set the file_name message header on a message reaching the transformer can cause the resulting .zip archive to be written to an arbitrar...

CVE-2026-59274

Spring Integration is affected by an unbounded decompression flaw in the UnZipTransformer component, which does not limit decompressed entry size or entry count when processing zip archives. An attacker with low privileges can send a crafted zip archive (zip-bomb) over the network to exhaust JVM ...

CVE-2026-59293

Spring Integration versions 6.4.0–6.4.12, 6.5.0–6.5.10, and 7.0.0–7.0.5 are affected by a vulnerability in the underlying jCIFS client . Unless an application explicitly raises smbMinVersion, the client will negotiate down to SMB1/CIFS , which lacks mandatory signing and encryption, exposing it t...
