MEDIUM 4.3DOWNGRADE

CVE-2026-13699 is a medium-severity flaw (CVSS 4.3) affecting kuksa. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In Eclipse KUKSA Databroker version 0.6.1, the kuksa.val.v2.VAL/PublishValue gRPC handler fails to validate the existence of the optional data_point field in PublishValueRequest. When a request contains a valid signal_id but omits data_point, the server directly calls unwrap() on request.data_point, triggering a panic in the Tokio worker thread. This issue can be triggered by any client holding a valid JWT token. Unauthenticated or invalid-token

eclipse kuksa DOWNGRADE

Affected: 0.6.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.6.1

1. Check installed version

apt-cache policy kuksa || rpm -q kuksa || kuksa --version

2. No fixed release: DOWNGRADE to a release before 0.6.1 (Debian / Ubuntu)

apt-cache madison kuksa sudo apt install kuksa=<VERSION_BEFORE_0.6.1> sudo apt-mark hold kuksa

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list kuksa sudo dnf downgrade kuksa-<VERSION_BEFORE_0.6.1> sudo dnf versionlock add kuksa

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.
