CRITICAL 9.8REMOTEDOWNGRADE

CVE-2025-69981 is a critical-severity flaw (CVSS 9.8) affecting fuxa. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

FUXA v1.2.7 contains an Unrestricted File Upload vulnerability in the `/api/upload` API endpoint. The endpoint lacks authentication mechanisms, allowing unauthenticated remote attackers to upload arbitrary files. This can be exploited to overwrite critical system files (such as the SQLite user database) to gain administrative access, or to upload malicious scripts to execute arbitrary code.

frangoteam fuxa DOWNGRADE

Affected: 1.2.7

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.2.7

1. Check installed version

apt-cache policy fuxa || rpm -q fuxa || fuxa --version

2. No fixed release: DOWNGRADE to a release before 1.2.7 (Debian / Ubuntu)

apt-cache madison fuxa sudo apt install fuxa=<VERSION_BEFORE_1.2.7> sudo apt-mark hold fuxa

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

dnf --showduplicates list fuxa sudo dnf downgrade fuxa-<VERSION_BEFORE_1.2.7> sudo dnf versionlock add fuxa

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.
