CVE-2025-65790 is a medium-severity flaw (CVSS 6.1) affecting fuguhub. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A reflected cross-site scripting (XSS) vulnerability exists in FuguHub 8.1 when serving SVG files through the /fs/ file manager interface. FuguHub does not sanitize or restrict script execution inside SVG content. When a victim opens a crafted SVG containing an inline <script> element, the browser executes the attacker-controlled JavaScript.

realtimelogic fuguhub DOWNGRADE

Affected: 8.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 8.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 8.1 (Debian / Ubuntu)

apt-cache madison fuguhub sudo apt install fuguhub=<VERSION_BEFORE_8.1> sudo apt-mark hold fuguhub

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

dnf --showduplicates list fuguhub sudo dnf downgrade fuguhub-<VERSION_BEFORE_8.1> sudo dnf versionlock add fuguhub

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.
