CVE-2026-47859 Unbounded memory allocation in RFC6587SyslogDeserializer (octet-counted framing) — remote DoS

RFC6587SyslogDeserializer, used by the Spring Integration syslog TCP inbound adapter to decode RFC 6587 / RFC 5424 frames, trusts the sender-supplied octet count of an octet-counted frame and allocates a byte array of exactly that size with no upper bound. Spring Integration 7.1.0 Spring...

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-2026-47856 JsonToObjectTransformer resolves the json__TypeId__ message header to an arbitrary class without an allow-list

Spring Integration's JSON to object conversion uses the jsonTypeId header to choose the deserialization target type, and resolves that header value to a class with ClassUtils.forName and no type/package allow-list. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0...

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 ...

Race Condition

Overview Affected versions of this package are vulnerable to Race Condition via the ScriptEngine process. An attacker can access sensitive data from other requests or cause unexpected exceptions by triggering concurrent script evaluations. Remediation Upgrade...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the RFC6587SyslogDeserializer. An attacker can cause excessive memory consumption and potentially exhaust system resources by sending frames with arbitrarily large declared lengths...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the setBeanClassLoader process. An attacker can execute arbitrary code by injecting malicious serialized data into the INTMESSAGE.MESSAGECONTENT field. This is only exploitable if the deserializatio...

Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

Overview Affected versions of this package are vulnerable to Improper Neutralization of Special Elements in Output Used by a Downstream Component 'Injection' in the decodeNativeFormat. An attacker can inject arbitrary entries into MessageHeaders, including sensitive control headers, by sending...

Exposure of Data Element to Wrong Session

Overview Affected versions of this package are vulnerable to Exposure of Data Element to Wrong Session via the fluxTransform when used with an asynchronous or reordering fluxFunction that emits raw payloads. An attacker can access another user's reply headers and cause reply mis-routing by sendin...

Symlink Attack

Overview Affected versions of this package are vulnerable to Symlink Attack via the ZipTransformer process. An attacker can overwrite or plant files in arbitrary directories by pre-creating a symbolic link at /tmp/ziptransformer before the application starts, causing extracted archive contents an...

Directory Traversal

Spring Integration is vulnerable to Directory Traversal. The vulnerability is due to insufficient validation of file paths received from malicious or compromised FTP/SFTP/SMB servers, which allows an attacker to write arbitrary content to files outside the configured local directory...

K000162431: Spring Integration vulnerability CVE-2026-40987
