Remote JVM termination via nested-array allowlist bypass
Published Aug 27, 2026 · Updated Aug 28, 2026
Denial of service in affected Spring AMQP releases allows remote attackers to terminate a consumer JVM with a hostile AMQP message. Java deserialization checks an array type against the allowlist without resolving its ultimate component, so nested arrays pass and recurse until StackOverflowError. An attacker must be able to publish to a consumed queue; the default JavaLangErrorHandler calls System.exit(99), stopping every workload in that JVM.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=2.4.18
- Affected versionversion=3.2.0 <=3.2.12
- Affected versionversion=4.0.0 <=4.0.4
- Affected versionversion=4.1.0
