HIGH 7.7DOWNGRADEDOWNGRADE

CVE-2026-23689 is a high-severity flaw (CVSS 7.7) affecting advanced planning and optimization, supply chain management. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Due to an uncontrolled resource consumption (Denial of Service) vulnerability, an authenticated attacker with regular user privileges and network access can repeatedly invoke a remote-enabled function module with an excessively large loop-control parameter. This triggers prolonged loop execution that consumes excessive system resources, potentially rendering the system unavailable. Successful exploitation results in a denial-of-service condition

Why this priority

sap advanced planning and optimization DOWNGRADE

Affected: 713 · 714

Fixed in: no fixed release known

Safe to downgrade to: a release before 713

1. Check installed version

apt-cache policy advanced-planning-and-optimization || rpm -q advanced-planning-and-optimization || advanced-planning-and-optimization --version

2. No fixed release: DOWNGRADE to a release before 713 (Debian / Ubuntu)

apt-cache madison advanced-planning-and-optimization sudo apt install advanced-planning-and-optimization=<VERSION_BEFORE_713> sudo apt-mark hold advanced-planning-and-optimization

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

dnf --showduplicates list advanced-planning-and-optimization sudo dnf downgrade advanced-planning-and-optimization-<VERSION_BEFORE_713> sudo dnf versionlock add advanced-planning-and-optimization

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.

2. No fixed release: DOWNGRADE to a release before 700 (Debian / Ubuntu)

apt-cache madison supply-chain-management sudo apt install supply-chain-management=<VERSION_BEFORE_700> sudo apt-mark hold supply-chain-management

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

dnf --showduplicates list supply-chain-management sudo dnf downgrade supply-chain-management-<VERSION_BEFORE_700> sudo dnf versionlock add supply-chain-management

Downgrade risk
