|---|---|---|---|---|---|---|
| CVE-2026-43891 | changedetection.io is a free open source web page change detection tool. Prior to 0.55.1, the vulnerability is caused by trusting attacker-controlled snapshot paths restored from backup files. The vulnerable flow starts in the backup restore logic. When a backup ZIP is restored, the application extracts the archive and copies each restored watch UUID directory directly into the live datastore using shutil.copytree(entry.path, dst_dir). This preserves attacker-controlled files inside the restored | [email protected] | 7.5 | 0.03% | 2026-05-12 | 2026-05-15 |
| CVE-2026-41895 | 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 directly with etree.fromstring(...). | [email protected] | 8.2 | 0.04% | 2026-05-12 | 2026-05-13 |
| CVE-2026-35490 | 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 original undecorated function, and the auth wrapper is never in the call chain. This silently disables authentication on these routes.

| CVE-2026-35000 | ChangeDetection.io versions prior to 0.54.7 contain a protection bypass vulnerability in the SafeXPath3Parser implementation that allows attackers to read arbitrary local files by using unblocked XPath 3.0/3.1 functions such as json-doc() and similar file-access primitives. Attackers can exploit the incomplete blocklist of dangerous XPath functions to access sensitive data from the local filesystem. | [email protected] | 7.1 | 0.05% | 2026-04-01 | 2026-04-21 |
| CVE-2026-33981 | changedetection.io is a free open source web page change detection tool. Prior to 0.54.7, the `jq:` and `jqraw:` include filter expressions allow use of the jq `env` builtin, which reads all process environment variables and stores them as the watch snapshot. An authenticated user (or unauthenticated user when no password is set, the default) can leak sensitive environment variables including `SALTED_PASS`, `PLAYWRIGHT_DRIVER_URL`, `HTTP_PROXY`, and any secrets passed as env vars to the containe | [email protected] | 8.3 | 0.02% | 2026-03-27 | 2026-04-02 |
| CVE-2026-29065 | changedetection.io is a free open source web page change detection tool. Prior to version 0.54.4, a Zip Slip vulnerability in the backup restore functionality allows arbitrary file overwrite via path traversal in uploaded ZIP archives. This issue has been patched in version 0.54.4. | [email protected] | 8.8 | 0.03% | 2026-03-06 | 2026-03-10 |
| CVE-2026-29039 | changedetection.io is a free open source web page change detection tool. Prior to version 0.54.4, the changedetection.io application allows users to specify XPath expressions as content filters via the include_filters field. These XPath expressions are processed using the elementpath library which implements XPath 3.0/3.1 specification. XPath 3.0 includes the unparsed-text() function which can read arbitrary files from the filesystem. The application does not validate or sanitize XPath expressio | [email protected] | 8.8 | 0.01% | 2026-03-06 | 2026-03-10 |
| CVE-2026-29038 | changedetection.io is a free open source web page change detection tool. Prior to version 0.54.4, there is a reflected cross-site scripting (XSS) vulnerability identified in the /rss/tag/ endpoint of changedetection.io. The tag_uuid path parameter is reflected 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. This issue has been patched in version 0.54.4. | [email protected] | 6.1 | 0.02% | 2026-03-06 | 2026-03-10 |
| 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 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.

| CVE-2026-27645 | 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 0.54.1 contains a fix for the issue. | [email protected] | 6.1 | 0.71% | 2026-02-25 | 2026-02-25 |
| CVE-2026-25527 | changedetection.io is a free open source web page change detection tool. In versions prior to 0.53.2, the `/static/<group>/<filename>` 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., `flask_app.py`). Version 0.53.2 fixes the issue. | [email protected] | 5.3 | 0.06% | 2026-02-19 | 2026-02-19 |
| CVE-2024-23329 | changedetection.io is an open source tool designed to monitor websites for content changes. In affected versions the API endpoint `/api/v1/watch/<uuid>/history` can be accessed by any unauthorized user. As a result any unauthorized user can check one's watch history. However, because unauthorized party first needs to know a watch UUID, and the watch history endpoint itself returns only paths to the snapshot on the server, an impact on users' data privacy is minimal.

| CVE-2023-24769 | Changedetection.io before v0.40.1.1 was discovered to contain a stored cross-site scripting (XSS) vulnerability in the main page. This vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the URL parameter under the "Add a new change detection watch" function. | [email protected] | 5.4 | 0.75% | 2023-02-17 | 2026-02-19 |
