# Synology DSM: path traversal in contentextract lets signed-in users read files

Link for people: https://infrastack.ai/live/CVE-2026-74850 (this .md is for agents)

A path traversal flaw in the contentextract component of Synology DiskStation Manager lets a logged-in user read specific files outside the intended directory. The sources say an authenticated remote user can read those files, but do not list which files.

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

## How to check

- Open DSM and check the installed version under Control Panel > Info Center (`7.3.2-86009-5` or `7.4.1-90080-1` or later is the fixed range per the advisory)

## Fix

- Synology DSM before `7.3.2-86009-5` on the 7.3 line, and before `7.4.1-90080-1` on the 7.4 line, per the NVD description

## Timeline

- 2026-11-12T04:47:09+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-74850

## From the sources

An improper limitation of a pathname to a restricted directory vulnerability in the contentextract in Synology DiskStation Manager (DSM) before 7.3.2-86009-5 and 7.4.1-90080-1 allows remote authenticated users to read specific files.
