Routine

MEDIUM 6.5UPGRADE

CVE-2026-59320 is a medium-severity flaw (CVSS 6.5) affecting spring advanced message queuing protocol. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

When a container-level ErrorHandler is configured (the mitigation for finding 221000), each delivery whose processing throws still permanently consumes one link credit. After initialCredits (default 100) failing messages the receiver's credit reaches zero and the broker stops delivering, leaving the listener silently stalled while isRunning() remains true. Spring AMQP 4.1.0

Why this priority

No elevated risk signals yet

vmware spring advanced message queuing protocol UPGRADE

Affected: >= 4.1.0 and < 4.1.1

Fixed in: 4.1.1

Safe to downgrade to: a release before 4.1.0

1. Check installed version

apt-cache policy spring-advanced-message-queuing-protocol || rpm -q spring-advanced-message-queuing-protocol || spring-advanced-message-queuing-protocol --version

2. UPGRADE to 4.1.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade spring-advanced-message-queuing-protocol

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-advanced-message-queuing-protocol

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 4.1.0 (Debian / Ubuntu)

apt-cache madison spring-advanced-message-queuing-protocol sudo apt install spring-advanced-message-queuing-protocol=<VERSION_BEFORE_4.1.0> sudo apt-mark hold spring-advanced-message-queuing-protocol

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list spring-advanced-message-queuing-protocol sudo dnf downgrade spring-advanced-message-queuing-protocol-<VERSION_BEFORE_4.1.0> sudo dnf versionlock add spring-advanced-message-queuing-protocol

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
