CVE-2024-51483 [MEDIUM] CWE-22 CVE-2024-51483: changedetection.io is free, open source web page change detection software. Prior to version 0.47.5, changedetection.io is free, open source web page change detection software. Prior to version 0.47.5, when a WebDriver is used to fetch files, `source:file:///etc/passwd` can be used to retrieve local system files, where the more traditional `file:///etc/passwd` gets blocked. Version 0.47.5 fixes the issue.

CVE-2026-25527 [MEDIUM] CWE-22 CVE-2026-25527: changedetection.io is a free open source web page change detection tool. In versions prior to 0.53.2 changedetection.io is a free open source web page change detection tool. In versions prior to 0.53.2, the `/static//` route accepts `group=".."`, which causes `send_from_directory("static/..", filename)` to execute. This moves the base directory up to `/app/changedetectionio`, enabling unauthenticated local file read of application source files (e.g.

CVE-2026-29065 [CRITICAL] CWE-22 CVE-2026-29065: changedetection.io is a free open source web page change detection tool. Prior to version 0.54.4, a changedetection.io is a free open source web page change detection tool.

This issue has been patched in version 0.54.4.

CVE-2026-27645 [MEDIUM] CWE-79 CVE-2026-27645: changedetection.io is a free open source web page change detection tool. In versions prior to 0.54.1 changedetection.io is a free open source web page change detection tool. In versions prior to 0.54.1, the RSS single-watch endpoint reflects the UUID path parameter directly in the HTTP response body without HTML escaping. Since Flask returns text/html by default for plain string responses, the browser parses and executes injected JavaScript. Version

CVE-2026-35490 [CRITICAL] CWE-863 CVE-2026-35490: changedetection.io is a free open source web page change detection tool. Prior to 0.54.8, the @login changedetection.io is a free open source web page change detection tool. Prior to 0.54.8, the @login_optionally_required decorator is placed before (outer to) @blueprint.route() instead of after it. In Flask, @route() must be the outermost decorator because it registers the function it receives. When the order is reversed, @route() registers the o

CVE-2025-62780 [MEDIUM] CWE-79 CVE-2025-62780: changedetection.io is a free open source web page change detection tool. A Stored Cross Site Scripti changedetection.io is a free open source web page change detection tool. A Stored Cross Site Scripting is present in changedetection.io Watch update API in versions prior to 0.50.34 due to insufficient security checks. Two scenarios are possible. In the first, an attacker can insert a new watch with an arbitrary URL which really points to a web page.

CVE-2026-27696 [HIGH] CWE-918 CVE-2026-27696: changedetection.io is a free open source web page change detection tool. In versions prior to 0.54.1 changedetection.io is a free open source web page change detection tool. 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.

CVE-2024-51998 [HIGH] CWE-22 CVE-2024-51998: changedetection.io is a free open source web page change detection tool. The validation for the file changedetection.io is a free open source web page change detection tool. The validation for the file URI scheme falls short, and results in an attacker being able to read any file on the system. This issue only affects instances with a webdriver enabled, and `ALLOW_FILE_URI` false or not defined. The check used for URL protocol, `is_safe_url`, allows `

CVE-2024-56509 [HIGH] CWE-22 CVE-2024-56509: changedetection.io is a free open source web page change detection, website watcher, restock monitor changedetection.io is a free open source web page change detection, website watcher, restock monitor and notification service.

CVE-2026-41895 [HIGH] CWE-611 CVE-2026-41895: changedetection.io is a free open source web page change detection tool. In 0.54.9 and earlier, xpat changedetection.io is a free open source web page change detection tool. In 0.54.9 and earlier, xpath_filter() switches to XML mode for XML/RSS content and creates etree.XMLParser(strip_cdata=False) without explicitly disabling external entity resolution, external DTD loading, or network-backed entity lookup. The helper then parses untrusted XML bytes
