CVE-2025-24889: The SecureDrop Client is a desktop application for journalists to communicate with sources and work with submissions on the SecureDrop Workstation.

The SecureDrop Client is a desktop application for journalists to communicate with sources and work with submissions on the SecureDrop Workstation.

The SecureDrop Client is a desktop application for journalists to communicate with sources and work with submissions on the SecureDrop Workstation. Prior to versions 0.14.1 and 1.0.1, an attacker who has already gained code execution in a virtual machine on the SecureDrop Workstation could gain code execution in the `sd-log` virtual machine by sending a specially crafted log entry. The vulnerability is not exploitable remotely and requires an attacker to already have code execution on one of the other virtual machines (VMs) of the system. Due to the Workstation's underlying usage of Qubes for strong isolation, the vulnerability would have allowed lateral movement between any log-enabled VM and the `sd-log` VM, but no further. The SecureDrop workstation collects logs centrally in an isolated virtual machine named `sd-log` for easy export for support and debugging purposes. The `sd-log` VM is completely isolated from the internet and ingests logs via a narrow Qubes RPC policy that allows for specific inter-VM communication via the Xen vchan protocol used by Qubes's qrexec mechanism. A path traversal bug was found in the logic used to choose where to write the log file for a specific

What it means for a small business

If your business uses securedrop-client, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.19%, higher than 9% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 28, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
