CVE-2025-8154 is a medium-severity flaw (CVSS 5.3) affecting api control plane, api manager, traffic manager. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
In Webhook API invocations, the component accepts user-supplied input for HTTP request headers without sufficient validation or sanitization, allowing these headers to be injected into HTTP responses. By exploiting this vulnerability, a malicious actor can inject or overwrite arbitrary HTTP response headers. This can lead to various adverse effects, including the manipulation of browser caching, alteration of security-related headers, and the in

wso2 api control plane UPGRADE
Affected: >= 4.5.0 and < 4.5.0.21
Fixed in: 4.5.0.21
Safe to downgrade to: a release before 4.5.0
1. Check installed version
apt-cache policy api-control-plane || rpm -q api-control-plane || api-control-plane --version
2. UPGRADE to 4.5.0.21 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade api-control-plane
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade api-control-plane
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 4.5.0 (Debian / Ubuntu)
apt-cache madison api-control-plane
sudo apt install api-control-plane=<VERSION_BEFORE_4.5.0>
sudo apt-mark hold api-control-plane
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list api-control-plane
sudo dnf downgrade api-control-plane-<VERSION_BEFORE_4.5.0>
sudo dnf versionlock add api-control-plane
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.
