In versions prior to 0.54.1, changedetection.io is vulnerable to Server-Side Request Forgery (SSRF) because the URL validation function `is_safe_valid_url()` does not validate the resolved IP address of watch URLs against private, loopback, or link-local address ranges. An authenticated user (or any user when no password is configured, which is the default) can add a watch for internal network URLs. The application fetches these URLs server-side, stores the response content, and makes it viewable through the web UI \u2014 enabling full data exfiltration from internal services. Version 0.54.1 contains a fix for the issue.<\/p>\n<p>Severity: 0.0 | NA<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2026-27696 Published : Feb. 25, 2026, 4:16 a.m. | 51\u00a0minutes ago Description : changedetection.io is a free open source web page change detection tool.
