CVE-2026-95656: dgtlmoon changedetection.io server-side request forgery in preview endpoint

CVE-2026-95656 · Severity: high · CVSS 7.3 · Published 2026-09-22

changedetection.io is a web monitoring tool that tracks website changes and alerts users to modifications. A flaw in the preview endpoint allows attackers to manipulate the URL parameter to perform server-side request forgery (SSRF), enabling them to make the server access internal resources or external systems on behalf of the attacker. This could lead to unauthorized data access or facilitate further attacks against internal infrastructure.

Technologies: Dgtlmoon Changedetection.Io. Vendors: Dgtlmoon.

Technical details

The vulnerability exists in the add_watch_ui_snapshot function within changedetectionio/blueprint/add_watch_ui/__init__.py, where insufficient input validation on the URL parameter allows SSRF. An attacker can send a crafted request remotely to manipulate the server into making requests to arbitrary destinations.
