# CVE-2026-71863: SecureDrop: Onion Service client auth credentials copied to Monitor Server

- Severity: CVSS 2.6 (Low), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:L/I:N/A:N
- Known exploited (CISA KEV): no
- Fixed in: 2.16.1
- Published: 2026-11-06 · Updated: 2026-11-06

CVE-2026-71863 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 2.6 (low) and affects securedrop; fixed in 2.16.1.

## Summary

SecureDrop, an open-source whistleblower submission system, copies Onion Service client authentication credentials to the Monitor Server when the install playbook runs with journalist alerts disabled. An attacker would need to take over the privileged Monitor Server first, and would then need to reach it over the network with high-privilege access and a user action, so it is a hard path to exploit.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- freedomofpress securedrop: from 2.13.0, fixed in 2.16.1

## Description

SecureDrop is an open-source whistleblower submission system that media organizations can use to securely accept documents from, and communicate with anonymous sources. From 2.13.0 until 2.16.1, running the securedrop-admin install Ansible playbook with journalist alerts disabled leaves the journalist alert key filename empty, causing the copy task to transfer every file in ~/.config/securedrop-admin/, including Onion Service client authentication credentials, to the Monitor Server. An attacker must first compromise the privileged Monitor Server to obtain the credentials, and the credentials remain an additional protection layer rather than sufficient access by themselves because the Journalist Interface still requires a username, passphrase, and MFA, while SSH access still requires SSH keys. This issue is fixed in version 2.16.1.
