CWE-80: Basic XSS vulnerabilities

An authenticated user can perform XSS. This issue affects Apache Atlas versions 2.4.0 and earlier. Users are recommended to upgrade to version 2.5.0, which fixes the issue.

md-fileserver allows for local viewing of markdown files in a browser. Prior to version 1.10.3, a cross-site scripting (XSS) vulnerability exists in the application’s Markdown rendering logic. When user-supplied Markdown content is rendered, embedded raw HTML—including <script> tags—is processed and injected into the resulting page without sanitization, allowing arbitrary JavaScript execution in the context of the affected domain. This issue has been patched in version 1.10.3.

CVE-2026-34033 is a medium severity vulnerability in Apache Answer affecting versions before 2.0.1. It involves improper neutralization of script-related HTML tags (basic XSS) where user-supplied content is included in notification emails without proper escaping. This allows authenticated users to inject arbitrary HTML into emails sent to other users. The issue is fixed in Apache Answer version 2.0.1.

CVE-2026-44839 is a medium severity vulnerability in rabbitmq-server versions from 3.7.0 up to but not including 4.0.13, and from 4.1.0-alpha up to but not including 4.1.2. It involves improper neutralization of script-related HTML tags, classified as CWE-80, which is a basic cross-site scripting (XSS) vulnerability.

Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) vulnerability in SpabRice Nyla allows Code Injection. This issue affects Nyla: from n/a through 1.7.

The GDPR cookies module for Backdrop CMS (before 1.x-1.3.5) doesn't sufficiently protect visitors from Cross Site Scripting (XSS) if a malicious value has been provided for the optional 'Info content' field for the YouTube service. This is mitigated by the fact that an attacker must have a role with the permission "Create a GDPR Cookies Service" or "Edit any GDPR Cookies Service" and a site must have added a YouTube service as configuration.

CtrlPanel is open-source billing software for hosting providers. Versions 1.1.1 and prior contain a Stored Cross-Site Scripting (XSS) vulnerability exists in the admin role management interface. In app/Http/Controllers/Admin/RoleController.php, the datatable() method interpolates $role->name and $role->color directly into a <span> element's HTML and style attribute without sanitization, and the chained .rawColumns(['actions', 'name']) call instructs DataTables to render the name column as raw HTML, bypassing automatic output escaping. An admin with role creation or edit permissions can inject a payload such as <img src=x onerror="alert('XSS_POC')"> into the name or color fields, which is persisted to the database and executes in the browser of every admin who loads the /admin/roles page. This enables session hijacking via cookie theft, credential harvesting through fake login prompts or keyloggers, lateral privilege escalation by performing admin actions on behalf of victims, and a persistent backdoor that re-executes on every page load until the malicious role record is removed. This issue has been resolved in version 1.2.0.

The MapGeo – Interactive Geo Maps plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'map' parameter in the display-map shortcode in all versions up to, and including, 1.6.27 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

CVAT is an open source interactive video and image annotation tool for computer vision. From 2.5.0 to 2.63.0, an attacker who is able to create or edit an annotation guide on a task is able to add malicious JavaScript code, which will then run in the browser of anyone who opens this annotation guide. This code will be able to make arbitrary requests to CVAT with the victim user's privileges. This vulnerability is fixed in 2.64.0.

efw4.X is an Enterprise Framework for Web. Prior to 4.08.010, the previewServlet serves files with their detected MIME type based on file extension, without any content sanitization or security headers. Files with .html, .htm, or .svg extensions are served as text/html or image/svg+xml respectively, causing any embedded JavaScript to execute in the victim's browser within the application's origin. This vulnerability is fixed in 4.08.010.

Improper neutralization of script-related html tags in a web page (basic xss) in Visual Studio Code allows an unauthorized attacker to execute code locally.

Grimmory is a self-hosted digital library. Prior to version 2.3.1, a stored cross-site scripting (XSS) vulnerability in Grimmory's browser-based EPUB reader allows an attacker to embed arbitrary JavaScript in a crafted EPUB file. When a victim opens the book, the script executes in their browser with full access to the Grimmory application's session context. This can enable session token theft and account takeover, including administrative access if an administrator opens the affected book. This issue has been patched in version 2.3.1.

MapServer versions from 6.0 up to but not including 8.6.2 contain a reflected cross-site scripting (XSS) vulnerability in the WMS server component. This flaw allows unauthenticated attackers to inject arbitrary HTML or JavaScript into the browsers of users who open specially crafted WMS URLs. The vulnerability arises when using FORMAT=application/openlayers combined with an unsanitized SRS parameter in WMS 1.3.0 requests. The issue is fixed in version 8.6.2.

In th30d4y/IP from version 1.0.1 to before version 2.0.1, a DOM-Based Cross-Site Scripting (XSS) vulnerability was identified in an IP Reputation Checker application. Unsanitized user input was directly rendered in the browser, allowing attackers to execute arbitrary JavaScript. This issue has been patched in version 2.0.1.

Weblate is a web based localization tool. Prior to version 5.17.1, the Markdown renderer used in user comments and other user-provided content didn't properly sanitize some attributes. This issue has been patched in version 5.17.1.

Improper neutralization of Script-Related HTML tags in a web page (basic XSS) vulnerability in DivvyDrive Information Technologies Inc. DivvyDrive allows Cross-Site Scripting (XSS). This issue affects DivvyDrive: from 4.8.2.9 before 4.8.3.2.

HCL DFXAnalytics is affected by an Insecure Security Header Configuration vulnerability where the application utilizes the outdated X-XSS-Protection header, which could allow an attacker to exploit browser-specific rendering flaws or bypass security controls that should instead be managed by a robust Content Security Policy (CSP).

mailcow: dockerized is an open source groupware/email suite based on docker. In versions prior to 2026-03b, the user dashboard's "Seen successful connections" (login history) renders the client IP from login logs without HTML escaping. Because the server trusts the X-Real-IP header as the source IP for logging, an attacker can inject HTML/JS into this field. This Self-XSS can be exploited by a Login CSRF to force the victim into the attacker's account, and then read emails in a previous browser tab. Version 2026-03b fixes the vulnerability.

mailcow: dockerized is an open source groupware/email suite based on docker. In versions prior to 2026-03b, the Quarantine details modal injects attachment filenames into HTML without escaping, allowing arbitrary HTML/JS execution. An attacker can deliver an email with a crafted attachment name so that when an admin views the quarantine item, JavaScript executes in their browser, taking over their account. Version 2026-03b fixes the vulnerability.

CVE-2026-40872 is a critical cross-site scripting (XSS) vulnerability in mailcow-dockerized versions prior to 2026-03b. The vulnerability arises because the admin dashboard's Autodiscover logs render the EMailAddress value without HTML escaping, allowing an attacker to submit a crafted email address containing malicious HTML or JavaScript. This payload is stored in Redis and executed when an admin views the Autodiscover logs. The issue is fixed in version 2026-03b.
