A vulnerability was found in dgtlmoon changedetection.io up to 0.60.7. This affects the function static_content of the file changedetectionio/flask_app.py of the component Screenshot Handler. Performing a manipulation of the argument filename results in path traversal. It is possible to initiate the attack remotely.…

A vulnerability has been found in dgtlmoon changedetection.io up to 0.60.7. The impacted element is the function check_authentication of the file changedetectionio/flask_app.py of the component Authentication Hook. Such manipulation leads to improper authentication. The attack may be performed from remote. The exploit…

A flaw has been found in dgtlmoon changedetection.io up to 0.60.7. The affected element is the function check_password of the file changedetectionio/flask_app.py of the component Hash Comparison. This manipulation of the argument Password causes observable timing discrepancy. The attack is possible to be carried out…

changedetection.io through 0.60.6 fails to validate the Goto URL action in browser steps, allowing unauthenticated attackers to access internal addresses. Attackers can supply arbitrary internal URLs in the optional_value parameter to retrieve responses from restricted network locations.

changedetection.io through 0.60.6 fails to escape the scraped page title in HTML notifications, allowing arbitrary markup injection. Attackers can place malicious markup in monitored page titles that reaches notification channels like email and Telegram as live content when the watch_title token is used in templates.

changedetection.io's /login route checks the submitted password against a single PBKDF2-HMAC-SHA256 hash with no per-IP or per-session rate limiting, failed-attempt counter, or lockout (no rate-limiting library is present in requirements.txt).

changedetection.io's /settings save handler builds an update dict from form.data['application'] and blind-merges it into the stored application settings via .update.

changedetection.io's REST API resources are protected by an @auth.check_token decorator validating the caller's x-api-key header, except the Spec resource registered at /api/v1/full-spec (changedetectionio/api/Spec.py), whose get method carries neither @auth.check_token nor @validate_openapi_request.

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…

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…

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…

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…

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…

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.

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…

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.…

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…

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…

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…

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…

changedetection.io is a free open source web page change detection, website watcher, restock monitor and notification service. Prior to version 0.50.4, errors in filters from website page change detection watches were not being filtered resulting in a cross-site scripting (XSS) vulnerability. This issue has been…

changedetection.io is a free open source web page change detection, website watcher, restock monitor and notification service. Improper input validation in the application can allow attackers to perform local file read (LFR) or path traversal attacks. These vulnerabilities occur when user input is used to construct…
