Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Valhalla is an open source routing engine and accompanying libraries for use with OpenStreetMap data. Versions 3.6.3 and prior are vulnerable to reflected cross-site scripting (XSS) due to improper neutralization of input in the JSONP callback parameter. When a request specifies a JSONP callback, the value is reflected directly into the HTTP response body with Content-Type: application/javascript, without any validation, output encoding, or allowlist filtering. An attacker can craft a URL containing arbitrary JavaScript in the callback parameter; if a victim is induced to load that URL via a <script src="..."> tag, the injected script executes in the context of the serving origin, potentially leading to session token theft, credential disclosure, or actions performed on behalf of the victim. This issue was not fixed at time of publication.Show less

WordPress appointment-booking-calendar 1.1.24 contains multiple privilege escalation vulnerabilities that allow unauthenticated attackers to modify calendar settings and inject persistent cross-site scripting payloads through the admin.php page parameters. Attackers can inject malicious JavaScript into the 'ict' and 'ics' options or the calendar 'name' parameter via GET requests to execute arbitrary scripts when the calendar is displayed or accessed in the administration interface.Show less

WordPress Booking Calendar Contact Form 1.0.23 contains privilege escalation and stored cross-site scripting vulnerabilities that allow authenticated users to modify plugin options and inject malicious scripts by failing to verify user privileges and sanitize input parameters. Attackers with subscriber-level accounts can inject XSS payloads through parameters like price, name, calendar_language, and email_confirmation_to_user via admin-ajax.php and admin.php endpoints to execute arbitrary JavaScript in administrator browsers.Show less

WordPress CP Polls 1.0.8 contains a persistent cross-site scripting vulnerability that allows attackers to inject malicious scripts through unsanitized file upload functionality. Attackers can upload files containing script payloads with event handlers like onerror attributes to execute arbitrary JavaScript in the browsers of users viewing the affected content.Show less

A vulnerability has been found in Intelliants Subrion CMS up to 4.0.3. Affected by this issue is some unknown functionality of the component Blocks Endpoint. Such manipulation of the argument CSS class name leads to cross site scripting. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.Show less

A vulnerability has been found in SourceCodester CET Automated Grading System with AI Predictive Analytics 1.0. The impacted element is an unknown function of the file /index.php. The manipulation of the argument action leads to cross site scripting. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used.Show less

The Online Scheduling and Appointment Booking System – Bookly plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'bookly-customer-full-name' cookie in versions up to, and including, 27.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires 'Remember personal information in cookies' setting to be enabled (disabled by default).Show less

The Canvas plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tag' parameter in all versions up to, and including, 2.5.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.Show less

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Anchor block in versions up to, and including, 2.0.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.Show less

The FooGallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'custom_attribute_key' shortcode parameter in versions up to, and including, 3.1.31 This is due to an incomplete JavaScript event handler blacklist in the foogallery_sanitize_javascript() function, which blocks only a subset of HTML event attributes (onmouseover, onmouseout, onpointerenter, onclick, onload, onchange, onerror) while permitting others such as 'onmouseenter', combined with the failure to escape the attribute key when building the gallery container HTML in foogallery_build_container_attributes_safe(). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.Show less

The GPTranslate – Multilingual AI Translation for WordPress: Automatically Translate Websites plugin for WordPress is vulnerable to Stored Cross-Site Scripting via REST API Translation Storage in all versions up to, and including, 2.31 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The deterministically derived API key (sha256 of the site URL) is printed in the HTML source of every page via the JavaScript variable gptApiKey, meaning any unauthenticated visitor can retrieve the key and submit malicious translation payloads to the /wp-json/gptranslate/v1/request endpoint without any additional precondition.Show less

The Store Locator WordPress plugin before 1.6.9 does not sanitize and escape store logo metadata before storing it and outputting it on the Store Locator WordPress plugin before 1.6.9 admin page, allowing high-privileged users such as administrators to perform Stored Cross-Site Scripting attacks even when the `unfiltered_html` capability is disallowed (e.g. in a multisite network).Show less

Allegra downloadAttachment Cross-Site Scripting Authentication Bypass Vulnerability. This vulnerability allows remote attackers to execute arbitrary script on affected installations of Allegra. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the downloadAttachment method. The issue results from the lack of proper validation of user-supplied data, which can lead to the injection of arbitrary script. An attacker can leverage this vulnerability to execute script in the context of the current user. Was ZDI-CAN-28236.Show less

ApostropheCMS is an open-source Node.js content management system. Versions up to and including 1.4.2 of the `@apostrophecms/seo` package injects the Google Analytics Tracking ID (`seoGoogleTrackingId`) and Google Tag Manager ID (`seoGoogleTagManager`) directly into `<script>` tag bodies using JavaScript template literals without any sanitization or validation. Any user with editor-level access (the default role for content managers) can set these fields to a malicious value, resulting in stored XSS that executes on every page for every visitor of the site. As of time of publication, no known patched versions are available.Show less

MISP contains a reflected cross-site scripting vulnerability in the UiBeta event index view. The urlparams value is inserted into an inline JavaScript handler using HTML escaping inside a single-quoted JavaScript string. Because browsers HTML-decode attribute values before JavaScript parsing, a crafted searcheventinfo value can restore encoded quote characters and break out of the JavaScript string. An attacker could craft a malicious URL that, when opened by a victim using the UiBeta event index, executes arbitrary JavaScript in the victim’s browser in the context of the MISP instance. The issue is fixed by encoding the value as a JavaScript string literal with json_encode() before applying HTML escaping at the attribute layer.Show less
