Improper Neutralization of Script in Attributes in a Web Page

MyBB is free and open source forum software. Prior to 1.8.40, the Contact module does not validate a redirect URL or protocol correctly, resulting in an open redirect and reflected JavaScript code injection. contact.php accepts the redirect target from the from HTTP parameter in $mybb->input['from'] or the Referer HTTP header in $_SERVER['HTTP_REFERER'] and passes it to redirect() without sufficient verification. A javascript: URI becomes the target of the `Click here if you don't want to wait any longer` link because $force_redirect is true, allowing script execution when a victim selects the link. This issue is fixed in version 1.8.40.Show less

Trilium Notes is a cross-platform, hierarchical note taking application focused on building large personal knowledge bases. Prior to 0.103.0, the #iconClass label value is returned raw by getNoteIcon() and inserted without HTML attribute encoding into class attributes in apps/client/src/widgets/quick_search.ts and apps/client/src/services/note_autocomplete.ts, allowing a stored payload to execute automatically when a victim opens a new tab or uses Ctrl+J and, because Electron enables nodeIntegration and disables contextIsolation, run operating-system commands as the victim. This issue is fixed in version 0.103.0.Show less

An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8. `django.contrib.admin.utils.display_for_field()` renders `URLField` values as clickable links in the admin without validating the URL. A value stored with an unsafe scheme is displayed as a link on changelist and read-only admin pages, which allows cross-site scripting against staff users who click the link. Exploitation requires the unsafe value to already be stored in the database. `URLField` validation through a `ModelForm` or the admin rejects unsafe schemes, so this affects applications that persist `URLField` data without running model validation, for example through direct queryset writes, deserialization, or bulk import of untrusted input. Django would like to thank Egor Saltykov for reporting this issue.Show less

Jodit Editor is a WYSIWYG editor with a built-in file browser & image editor. Prior to 4.12.31, Jodit's sanitizeHTMLElement method fails to use isDangerousUrl to normalize javascript: href values before checking the scheme, allowing case variants, control-byte prefixes, and embedded tabs or newlines to bypass filtering and execute attacker-controlled script when a victim clicks a stored link rendered by an application. This issue is fixed in version 4.12.31.Show less

Astro is a web framework for content-driven websites. In versions 3.10.0 through 7.0.3, when a transition:persist, transition:scope, or transition:persist-props directive is applied to a client-hydrated (client:*) component, Astro copied the directive value onto the rendered <astro-island> element without HTML-escaping it. If a developer reflects attacker-controlled input into one of these directives, an attacker can break out of the attribute and inject arbitrary HTML/JavaScript into the server-rendered output, resulting in reflected cross-site scripting (XSS). Exploitation requires the application developer to have written a non-idiomatic pattern — passing untrusted, request-derived input directly into a transition directive. Astro applications that do not route untrusted input into these directives are unaffected. This issue has been fixed in version 7.0.4.Show less

Kirby is an open-source content management system. Prior to 4.9.4 and 5.4.4, Kirby sites using the writer field in any blueprint allowed a scripting link to be included as the target of a link or email link in writer mark components, making the target clickable by the user who entered it and enabling self cross-site scripting in the Panel. This issue is fixed in versions 4.9.4 and 5.4.4.Show less

Jodit Editor is a WYSIWYG editor with a built-in file browser & image editor. In versions prior to 4.12.28, the built-in clean-html sanitizer can be bypassed by a MathML/<style> carrier that hides a dangerous element from the sanitizer's element walk, so a no-interaction event handler survives into the editor value, potentially causing Mutation XSS. When an application supplies attacker-influenced HTML to the editor's value-set or insertion paths, the sanitized output still contains a live <img ... onload=...> (or another non-onerror handler such as onfocus). A consumer that renders that output (element.innerHTML = editor.value) executes the handler with no user interaction. This issue has been fixed in version 4.12.28.Show less

Improper Neutralization of Script in Attributes in a Web Page vulnerability in pragdave earmark allows stored cross-site scripting via unescaped HTML attribute values. 'Elixir.Earmark.Transform':_make_att1/2 in lib/earmark/transform.ex splices attribute values verbatim between two literal " bytes: [" ", name, "=\"", value, "\""]. Text nodes are routed through the existing escape function which encodes " as &quot;, but attribute values never visit that path. A markdown link whose URL or title contains a bare " closes the attribute early and lets the trailing bytes be parsed by the browser as fresh HTML attributes. For example, [click](http://example.com/?a=x" onerror="alert(1)) renders as <a href="http://example.com/?a=x" onerror="alert(1)">click</a>, executing arbitrary JavaScript in the victim's browser. The earmark library is no longer maintained and has been retired on Hex. No patched version will be released. All releases from 1.4.1 onward are affected, and users should migrate to a maintained Markdown library such as MDEx. This issue affects earmark from 1.4.1 onward.Show less

OpenClaw before 2026.5.12 contains a cross-site scripting vulnerability in exported session HTML that preserves unsafe javascript: and data: links in generated content. Attackers can execute browser-side scripts if a trusted operator opens the exported file and activates a malicious link.Show less

Nuxt is an open-source web development framework for Vue.js. Prior to versions 3.21.7 and 4.4.7, <NuxtLink> did not validate the URL scheme of values bound to its to or href props before rendering them into the href attribute of the underlying <a> element. When an application binds attacker-controlled input (a query parameter, a CMS field, a user-supplied profile URL) to <NuxtLink :to> or :href, the attacker can supply a javascript: or vbscript: URL that is reflected verbatim into the rendered markup. Clicking the link executes the supplied script in the origin of the Nuxt application, resulting in reflected DOM-based cross-site scripting. A data:text/html,... payload reflected through the same sink does not execute in the application's origin but enables a same-tab phishing surface anchored to a legitimate application link. The same value was exposed to consumers of the component's custom slot via the href and route.href props, so applications that re-bind those values to their own anchors were affected identically. This issue has been patched in versions 3.21.7 and 4.4.7.Show less

Nuxt is an open-source web development framework for Vue.js. From versions 3.4.3 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6, navigateTo() with external: true generates a server-side HTML redirect body containing a <meta http-equiv="refresh"> tag. The destination URL is only sanitized by replacing " with %22, leaving <, >, &, and ' unencoded. An attacker who can influence the URL passed to navigateTo(url, { external: true }) can break out of the content="…" attribute and inject arbitrary HTML/JavaScript that executes under the application's origin. This issue has been patched in versions 3.21.6 and 4.4.6.Show less

Concrete CMS 9.5.0 and below is vulnerable to Reflected XSS in Legacy Pagination via HTML attribute injection. Concrete\Core\Legacy\Pagination builds pagination links by raw-interpolating its $URL field into href="" (<a href="{$linkURL}" …>). Any authenticated admin or report viewer with access to `/dashboard/reports/forms/legacy` who clicks the crafted URL fires the payload in their session. The Concrete CMS security team gave this vulnerability a CVSS v.4.0 score of 6.0 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N.

CVAT is an open source interactive video and image annotation tool for computer vision. In versions 2.2.0 through 2.54.0, an attacker is able to execute arbitrary JavaScript in a victim user's CVAT UI session, provided that they are able to create a maliciously crafted label in a CVAT task or project, then get the victim user to either edit that label, or view a shape that refers to that label; and/or get the victim user to upload a maliciously crafted SVG image when configuring a skeleton. This gives the attacker temporary access to all CVAT resources that the victim user can access. Version 2.55.0 fixes the issue.Show less

Saleor is an e-commerce platform. Starting in version 3.0.0 and prior to versions 3.20.108, 3.21.43, and 3.22.27, Saleor was allowing users to modify rich text fields with HTML without running any backend HTML cleaners thus allowing malicious actors to perform stored XSS attacks on dashboards and storefronts. Malicious staff members could craft script injections to target other staff members, possibly stealing their access and/or refresh tokens. This issue has been patched in versions 3.22.27, 3.21.43, and 3.20.108. In case of inability to upgrade straight away, a possible workaround is to use client-side cleaner.Show less

Stored cross-site scripting (XSS) vulnerability in the LMT Dashboard of the Perx Customer Engagement & Loyalty Platform allows an authenticated attacker to execute arbitrary JavaScript code in a victim's browser. The vulnerability is due to improper sanitization of SVG file uploads. An attacker can upload a malicious SVG file containing a script payload to a campaign. When another user views this image on the public LMT microsite, the script executes, which can lead to session hijacking, data theft, or other unauthorized actions.This issue affects Customer Engagement & Loyalty Platform before 4.617.4.Show less

An improper input neutralization vulnerability in the management web interface of the Palo Alto Networks PAN-OS® software enables an authenticated administrator to bypass system restrictions and execute arbitrary commands. The security risk posed by this issue is significantly minimized when CLI access is restricted to a limited group of administrators. Cloud NGFW and Prisma® Access are not affected by this vulnerability.Show less

The Volkov Labs Business Links panel for Grafana provides an interface to navigate using external links, internal dashboards, time pickers, and dropdown menus. Prior to version 2.4.0, a malicious actor with Editor privileges can escalate their privileges to Administrator and perform arbitrary administrative actions. This is possible because the plugin allows arbitrary JavaScript code injection in the [Layout] → [Link] → [URL] field. Version 2.4.0 contains a fix for the issue.Show less
