### Impact The prosemirror_to_html gem is vulnerable to Cross-Site Scripting (XSS) attacks through malicious HTML attribute values. While tag content is properly escaped, attribute values are not, allowing attackers to inject arbitrary JavaScript code. **Who is impacted:** - Any application using prosemirror_to_html to convert ProseMirror documents to HTML - Applications that process user-generated ProseMirror content are at highest risk - End users viewing the rendered HTML output could have malicious JavaScript executed in their browsers **Attack vectors include:** - `href` attributes with `javascript:` protocol: `<a href="javascript:alert(document.cookie)">` - Event handlers: `<div onclick="maliciousCode()">` - `onerror` attributes on images: `<img src=x onerror="alert('XSS')">` - Other HTML attributes that can execute JavaScript ### Patches A fix is currently in development. Users should upgrade to version **0.2.1** or later once released. The patch escapes all HTML attribute...

View CSAF 1. EXECUTIVE SUMMARY CVSS v4 8.7 ATTENTION: Exploitable remotely/Low attack complexity Vendor: Advantech Equipment: DeviceOn/iEdge Vulnerabilities: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') 2. RISK EVALUATION Successful exploitation of these vulnerabilities could result in a denial-of-service condition, remote code execution, or an attacker reading arbitrary files. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following version of DeviceOn/iEdge, an IoT management platform, is affected: DeviceOn/iEdge: Version 2.0.2 and prior 3.2 VULNERABILITY OVERVIEW 3.2.1 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION ('CROSS-SITE SCRIPTING') CWE-79 Insufficient input sanitization in the dashboard label or path can allow an attacker to trigger a device error causing information disclosure or data manipulation. CVE-2025-64302 has been assigned to this vuln...

### Impact OctoPrint versions up to and including 1.11.3 are affected by a vulnerability that allows injection of arbitrary HTML and JavaScript into Action Command notification and prompt popups generated by the printer. An attacker who successfully convinces a victim to print a specially crafted file could exploit this issue to disrupt ongoing prints, extract information (including sensitive configuration settings, if the targeted user has the necessary permissions for that), or perform other actions on behalf of the targeted user within the OctoPrint instance. ### Patches The vulnerability will be patched in version 1.11.4. ### Workaround OctoPrint administrators can mitigate the risk by disabling popups: - for Action Command notifications, uncheck _OctoPrint Settings -> Printer Notifications -> Enable popups_ - for Action Command prompts, set _OctoPrint Settings -> Printer Dialogs -> Enable support -> Never_ It is also strongly recommended to ensure that files being printed o...

### Summary OpenMage versions v20.15.0 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an admin with direct database access or the admin notification feed source to inject malicious scripts into vulnerable fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field. ### Details Unescaped translation strings and URLs are printed into contexts inside `app/code/core/Mage/Adminhtml/Block/Notification/Grid/Renderer/Actions.php`. A malicious translation or polluted data can inject script. - Link labels use __() without escaping. - ’deleteConfirm()’ embeds a message without escaping. ### PoC 1. Add XSS to admin locale (e.g. app/locale/en_US/local.csv): ``` "Read Details","<img src=x onerror=alert(123)>" "Mark as Read","<script>alert(123)</script>" ``` 2. Flush Cache. Make sure locale is set to en_US. 3. Add any admin notification (e.g. via test.php) ...

Multiple cross-site scripting (XSS) vulnerabilities in web content template’s select structure page in Liferay Portal 7.4.3.35 through 7.4.3.111, and Liferay DXP 2023.Q4.0 through 2023.Q4.10, 2023.Q3.1 through 2023.Q3.10, 7.4 update 35 through update 92 allow remote attackers to inject arbitrary web script or HTML via a crafted payload injected into a user’s (1) First Name, (2) Middle Name, or (3) Last Name text field.

Reflected cross-site scripting (XSS) vulnerability in Languauge Override in Liferay Portal 7.4.3.8 through 7.4.3.111, and Liferay DXP 2023.Q4.0 through 2023.Q4.10, 2023.Q3.1 through 2023.Q3.10, and 7.4 update 4 through update 92 allows remote attackers to inject arbitrary web script or HTML via the `_com_liferay_portal_language_override_web_internal_portlet_PLOPortlet_selectedLanguageId` parameter.

Cross-site scripting (XSS) vulnerability in the Blogs widget in Liferay Portal 7.4.0 through 7.4.3.111, and older unsupported versions, and Liferay DXP 2023.Q4.0 through 2023.Q4.10, 2023.Q3.1 through 2023.Q3.8, 7.4 GA through update 92, 7.3 GA through update 36, and older unsupported versions allows remote attackers to inject arbitrary web script or HTML via a crafted <iframe> injected into a blog entry's “Content” text field. The Blogs widget in Liferay DXP does not add the sandbox attribute to <iframe> elements, which allows remote attackers to access the parent page via scripts and links in the frame page.

### Impact Stored XSS vulnerabilities in Collections and Taxonomies allow authenticated users with content creation permissions to inject malicious JavaScript that executes when viewed by higher-privileged users. This affects: - Control panel users with permission to create or edit Collections and Taxonomies - Versions up to and including 5.22.0 The vulnerability can be exploited to: - Change a super admin's password (versions ≤ 5.21.0) - Change a super admin's email address to initiate password reset (version 5.22.0) - Gain unauthorized access to superadmin accounts The attack requires: - An authenticated user with control panel and content creation permissions - A super admin to view the compromised content ### Patches This has been fixed in 5.22.1. ### Credits Statamic thanks [Wojtek Chwala](https://github.com/wojtekchwala) for responsibly reporting the identified issues and working with us as we addressed them.

### Summary When using subrequest authentication, Anubis did not perform validation of the redirect URL and redirects user to any URL scheme. While most modern browsers do not allow a redirect to `javascript:` URLs, it could still trigger dangerous behavior in some cases. `GET https://example.com/.within.website/?redir=javascript:alert()` responds with `Location: javascript:alert()`. ### Impact Anybody with a subrequest authentication seems affected. Using `javascript:` URLs will probably be blocked by most modern browsers, but using custom protocols for third-party applications might still trigger dangerous operations. ### Note This was originally reported by @mbiesiad against Weblate.
