CVE-2025-55948 is a high-severity flaw (CVSS 7.3) affecting x-springboot. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

This vulnerability fundamentally arises from yzcheng90 X-SpringBoot 6.0's implementation of role-based access control (RBAC) through dual dependency on frontend menu systems and backend permission tables, without enforcing atomic synchronization between these components. The critical flaw manifests when frontend menu updates (such as privilege revocation) fail to propagate to the backend permission table in real-time, creating a dangerous desynch

yzcheng90 x-springboot DOWNGRADE

Affected: 6.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 6.0

1. Check installed version

apt-cache policy x-springboot || rpm -q x-springboot || x-springboot --version

2. No fixed release: DOWNGRADE to a release before 6.0 (Debian / Ubuntu)

apt-cache madison x-springboot sudo apt install x-springboot=<VERSION_BEFORE_6.0> sudo apt-mark hold x-springboot

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

dnf --showduplicates list x-springboot sudo dnf downgrade x-springboot-<VERSION_BEFORE_6.0> sudo dnf versionlock add x-springboot

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.
