Cross-site Scripting (XSS) - Reflected in GitHub repository thorsten/phpmyfaq prior to 3.2.2.

phpMyFAQ is an open source FAQ web application for PHP 8.1+ and MySQL, PostgreSQL and other databases. An attacker with admin privileges can upload an attachment containing JS code without extension and the application will render it as HTML which allows for XSS attacks.

phpMyFAQ before 4.1.2 contains a stored cross-site scripting vulnerability in SvgSanitizer::decodeAllEntities() that limits recursive entity decoding to 5 iterations, allowing attackers to bypass sanitization. Authenticated users with FAQ_EDIT permission can upload malicious SVG files with deeply nested ampersand encoding around numeric HTML entities to reconstruct javascript: URLs, which execute arbitrary JavaScript when clicked by other users viewing the uploaded SVG.

phpMyFAQ before 4.1.2 contains a stored cross-site scripting vulnerability in FAQ creation and update endpoints that bypass sanitization through encode-decode cycles. The vulnerability allows authenticated attackers with FAQ_ADD permission to inject malicious script tags via question or answer parameters, which execute in every visitor's browser when FAQ content is rendered with the raw Twig filter.

phpMyFAQ is an open source FAQ web application for PHP 8.1+ and MySQL, PostgreSQL and other databases. Due to insufficient validation on the `contentLink` parameter, it is possible for unauthenticated users to inject HTML code to the page which might affect other users. _Also, requires that adding new FAQs is allowed for guests and that the admin doesn't check the content of a newly added FAQ._ This vulnerability is fixed in 3.2.6.

phpMyFAQ is an open source FAQ web application for PHP 8.1+ and MySQL, PostgreSQL and other databases.

Adding a comment with content "<script>alert(1)</script>" reproduces the attack. This can be exploited by a user with administrator privileges in the User-Agent field. It can also be exploited by an outside party through the following steps: 1. Create a user with the surname `" onmouseover="alert(document.cookie)` and an empty first name. 2. With this user, create a ticket 3. As an administrator (or other privileged user) open the created ticket 4. On the "last update" field, put your mouse on the name of the user 5. The XSS fires This is fixed in version 9.4.6.

WeGIA is a web manager for charitable institutions. In versions prior to 3.6.10, a Stored Cross-Site Scripting (XSS) vulnerability allows an authenticated user to inject malicious JavaScript via the "Nome" field in the "Informações Pacientes" page. The payload is stored and executed when the patient information is viewed. Version 3.6.10 fixes the issue.

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to version 2.62.2, the EPUB preview function in File Browser is vulnerable to Stored Cross-Site Scripting (XSS). JavaScript embedded in a crafted EPUB file executes in the victim's browser when they preview the file. This issue has been patched in version 2.62.2.

ChurchCRM is an open-source church management system. Prior to 7.1.0, a stored cross-site scripting vulnerability exists in PersonView.php due to incorrect use of sanitizeText() as an output sanitizer for HTML attribute context. The function only strips HTML tags, it does not escape quote characters allowing an attacker to break out of the href attribute and inject arbitrary JavaScript event handlers. Any authenticated user with the EditRecords role can store the payload in a person's Facebook field. The XSS fires against any user who views that person's profile page, including administrators, enabling session hijacking and full account takeover. This vulnerability is fixed in 7.1.0.

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.15 and 8.6.41, an attacker who is allowed to upload files can bypass the file extension filter by appending a MIME parameter (e.g. `;charset=utf-8`) to the `Content-Type` header. This causes the extension validation to fail matching against the blocklist, allowing active content to be stored and served under the application's domain. In addition, certain XML-based file extensions that can render scripts in web browsers are not included in the default blocklist. This can lead to stored XSS attacks, compromising session tokens, user credentials, or other sensitive data accessible via the browser's local storage. The fix in versions 9.6.0-alpha.15 and 8.6.41 strips MIME parameters from the `Content-Type` header before validating the file extension against the blocklist. The default blocklist has also been extended to include additional XML-based extensions (`xsd`, `rng`, `rdf`, `rdf+xml`, `owl`, `mathml`, `mathml+xml`) that can render active content in web browsers. Note that the `fileUpload.fileExtensions` option is intended to be configured as an allowlist of file extensions that are valid for a specific application, not as a denylist. The default denylist is provided only as a basic default that covers most common problematic extensions. It is not intended to be an exhaustive list of all potentially dangerous extensions. Developers should not rely on the default value, as new extensions that can render active content in browsers might emerge in the future. As a workaround, configure the `fileUpload.fileExtensions` option to use an allowlist of only the file extensions that your application needs, rather than relying on the default blocklist.

The grafanacubism-panel plugin allows use of cubism.js in Grafana. In 0.1.2 and earlier, the panel's zoom-link handler passes a dashboard-editor-supplied URL directly to window.location.assign() / window.open() with no scheme validation. An attacker with dashboard Editor privileges can set the link to a javascript: URI; when any Viewer drag-zooms on the panel, the payload executes in the Grafana origin.

OneUptime is a solution for monitoring and managing online services. Prior to 10.0.23, the Markdown viewer component renders Mermaid diagrams with securityLevel: "loose" and injects the SVG output via innerHTML. This configuration explicitly allows interactive event bindings in Mermaid diagrams, enabling XSS through Mermaid's click directive which can execute arbitrary JavaScript. Any field that renders markdown (incident descriptions, status page announcements, monitor notes) is vulnerable. This vulnerability is fixed in 10.0.23.

Convos is an open source multi-user chat that runs in a web browser. Characters starting with "https://" in the chat window create an <a> tag. Stored XSS vulnerability using onfocus and autofocus occurs because escaping exists for "<" or ">" but escaping for double quotes does not exist. Through this vulnerability, an attacker is capable to execute malicious scripts. Users are advised to update as soon as possible.

Convos is an open source multi-user chat that runs in a web browser. You can't use SVG extension in Convos' chat window, but you can upload a file with an .html extension. By uploading an SVG file with an html extension the upload filter can be bypassed. This causes Stored XSS. Also, after uploading a file the XSS attack is triggered upon a user viewing the file. Through this vulnerability, an attacker is capable to execute malicious scripts. Users are advised to update as soon as possible.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, a stored cross-site scripting vulnerability in the CCDA document preview allows an attacker who can upload or send a CCDA document to execute arbitrary JavaScript in a clinician's browser session when the document is previewed. The XSL stylesheet sanitizes attributes for all other narrative elements but not for `linkHtml`, allowing `href="javascript:..."` and event handler attributes to pass through unchanged. Version 8.0.0.3 patches the issue.
