CVE-2025-5198 is a medium-severity flaw (CVSS 5.0) affecting advanced cluster security, stackrox. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A flaw was found in Stackrox, where it is vulnerable to Cross-site scripting (XSS) if the script code is included in a small subset of table cells. The only known potential exploit is if the script is included in the name of a Kubernetes “Role” object* that is applied to a secured cluster. This object can be used by a user with access to the cluster or through a compromised third-party product.

redhat advanced cluster security DOWNGRADE

Affected: 4.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.0

1. Check installed version

apt-cache policy advanced-cluster-security || rpm -q advanced-cluster-security || advanced-cluster-security --version

2. No fixed release: DOWNGRADE to a release before 4.0 (Debian / Ubuntu)

apt-cache madison advanced-cluster-security sudo apt install advanced-cluster-security=<VERSION_BEFORE_4.0> sudo apt-mark hold advanced-cluster-security

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

dnf --showduplicates list advanced-cluster-security sudo dnf downgrade advanced-cluster-security-<VERSION_BEFORE_4.0> sudo dnf versionlock add advanced-cluster-security

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.
