SCA: security update for github.com/MontFerret/ferret/v2 (GHSA-j6v5-g24h-vg4j)

high Tenable Self-Hosted Container Security Plugin ID 439597

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Ferret is a declarative system for working with web data. Prior to 2.0.0-alpha.4, a path traversal
 vulnerability in Ferret's IO::FS::WRITE standard library function allows a malicious website to write
 arbitrary files to the filesystem of the machine running Ferret. When an operator scrapes a website that
 returns filenames containing ../ sequences, and uses those filenames to construct output paths (a standard
 scraping pattern), the attacker controls both the destination path and the file content. This can lead to
 remote code execution via cron jobs, SSH authorized_keys, shell profiles, or web shells. This
 vulnerability is fixed in 2.0.0-alpha.4. (CVE-2026-34783)

Solution

Update the github.com/MontFerret/ferret/v2 library and its related packages to version 2.0.0-alpha.4 or later.
