# free-fs: share codes enforced only client-side, letting anyone download files

Link for people: https://infrastack.ai/live/CVE-2026-129164 (this .md is for agents)

Dromara free-fs versions 2.0.1 through 2.3.1 check share codes only in the browser, so the server does not require them. An attacker who knows a share ID can list and download the files in a code-protected share, including preview-only shares.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the free-fs version in the deployed project's dependency file or build output, looking for `2.0.1` through `2.3.1`
- Review whether any file shares rely on share codes for access control

## Fix

- free-fs: unknown (the sources do not name a fixed version)

## From the sources

Dromara free-fs 2.0.1 through 2.3.1 contains an authorization bypass vulnerability that allows attackers to access code-protected shares because share codes are enforced only client-side. Attackers knowing a share ID can call the share items and download endpoints to list and download files without the code, even on preview-only shares.
