CVE-2025-66905 is a high-severity flaw (CVSS 7.5) affecting tkfiles. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The Takes web framework's TkFiles take thru 2.0-SNAPSHOT fails to canonicalize HTTP request paths before resolving them against the filesystem. A remote attacker can include ../ sequences in the request path to escape the configured base directory and read arbitrary files from the host system.

takes tkfiles DOWNGRADE

Affected: 2.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.0 (Debian / Ubuntu)

apt-cache madison tkfiles sudo apt install tkfiles=<VERSION_BEFORE_2.0> sudo apt-mark hold tkfiles

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

dnf --showduplicates list tkfiles sudo dnf downgrade tkfiles-<VERSION_BEFORE_2.0> sudo dnf versionlock add tkfiles

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.
