CVE-2026-7366 is a medium-severity flaw (CVSS 4.2) affecting datapower gateway. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

IBM DataPower Gateway 11.0.0.0 through 11.0.0.1 and IBM DataPower Gateway 10.5.0.0 through 10.5.0.21 and IBM DataPower Gateway 10.6.0.0 through 10.6.0.9 allows a race condition that results in improper isolation of request state when handling the built‑in X‑Client‑IP header. Under concurrent request processing, X‑Client‑IP values may be contaminated across requests, enabling IP spoofing and disclosure of other clients’ IP addresses.

Why this priority

  • No elevated risk signals yet

A fixed release or distro patch exists.

Timeline

ibm datapower gateway UPGRADE
Affected: >= 10.5.0.0 and < 10.5.0.22 · >= 10.6.0.0 and < 10.6.0.10 · >= 11.0.0.0 and < 11.0.0.2
Fixed in: 10.5.0.22, 10.6.0.10, 11.0.0.2
Safe to downgrade to: a release before 10.5.0.0
1. Check installed version
apt-cache policy datapower-gateway || rpm -q datapower-gateway || datapower-gateway --version
2. UPGRADE to 10.5.0.22 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade datapower-gateway
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade datapower-gateway
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 10.5.0.0 (Debian / Ubuntu)
apt-cache madison datapower-gateway sudo apt install datapower-gateway=<VERSION_BEFORE_10.5.0.0> sudo apt-mark hold datapower-gateway
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list datapower-gateway sudo dnf downgrade datapower-gateway-<VERSION_BEFORE_10.5.0.0> sudo dnf versionlock add datapower-gateway
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.
