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

Markdown Preview Enhanced is a Markdown preview extension for Visual Studio Code. Prior to 0.8.30, Markdown Preview Enhanced reads repository-controlled .crossnote/head.html content and passes it through resolvePathsInHeader before inserting it into the head of the preview webview document without removing executable content. Script-capable markup executes while the document loads, before the React application and DOMPurify initialize, and can access acquireVsCodeApi to send messages from the webview to the extension host. Opening a Markdown preview in a malicious repository is sufficient to trigger the injected content, and no additional click within the notification or preview is required. This issue is fixed in version 0.8.30.Show less

lichess.org is the forever free, adless and open source chess server. Prior to commit c54596c9e1569d378fe20f80d4c790c6fdee54c4, a user who can add a chapter to a study can place attacker-controlled text in the PGN Annotator tag, which becomes Comment.Author.External and is returned verbatim by authorText. When a study node has at least two comments, ui/analyse/src/treeView/inlineView.ts interpolates that author string into HTML passed to the innerHTML hook without escaping it. Opening the affected study can therefore render stored attacker-controlled HTML and CSS for other viewers, including navigation to an attacker-controlled site, content spoofing, and CSS-based data exposure, although the site's content security policy blocks injected JavaScript. This vulnerability is fixed by commit c54596c9e1569d378fe20f80d4c790c6fdee54c4.Show less

DataEase is an open source data visualization and analysis tool. Prior to 2.10.26, authenticated users who can edit dataset fields and chart configuration can store an HTML-bearing dimension value in a bar-horizontal chart. When lengthLimit truncates the category axis label, configAxisLabelLengthLimit in core/core-frontend/src/views/chart/components/js/panel/common/common_antv.ts retrieves the full label and assigns it to the g2-tooltip-title element through innerHTML. A victim who opens the dashboard and hovers the truncated label can execute attacker-controlled JavaScript in the victim's DataEase session. This issue is fixed in version 2.10.26.Show less

DataEase is an open source data visualization and analysis tool. Prior to 2.10.26, authenticated users with folder creation permission can store HTML-bearing names through datasource/createFolder or datasetTree/save. The datasource and dataset Move to dialogs in core/core-frontend/src/views/visualized/data/datasource/form/CreatDsGroup.vue and core/core-frontend/src/views/visualized/data/dataset/form/CreatDsGroup.vue read the stored name from a node title attribute and assign search-highlighted content to innerHTML. When another user opens a Move to dialog and types in its search box, attacker-controlled JavaScript can execute in the victim's DataEase session. This issue is fixed in version 2.10.26.Show less

Discourse is an open-source discussion platform. Prior to 2026.9.0, 2026.8.1, 2026.7.3, and 2026.1.9, oEmbed processing treated an entire attacker-controlled HTML fragment as trusted when the fragment contained an iframe whose source matched the configured allowlist. A user with posting permission who controlled a public webpage and its oEmbed response could combine an allowlisted iframe with unrelated sibling HTML or CSS, causing stored visual overlays or other styled content to appear in post content and enabling misleading or fraudulent user interfaces. Exploitation requires a posting account, control of the fetched webpage and oEmbed response, and an allowlisted iframe source. The issue affects content integrity but does not expose restricted data, disrupt availability, or require interaction with Discourse Content Security Policy. This issue is fixed in versions 2026.9.0, 2026.8.1, 2026.7.3, and 2026.1.9.Show less

Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in Progress MOVEit Transfer (Ad Hoc module). This issue affects MOVEit Transfer: before 2025.1.6 and from 2026.0.0 before 2026.0.4.Show less

Gitea's Jupyter notebook renderer inserts the notebook's language_info.name metadata into a CSS class attribute while disabling sanitization and rendering directly in the main document without an iframe sandbox. A malicious repository notebook can supply multiple CSS classes that create a viewport-covering overlay and intercept clicks when another user views it. The reported impact is UI redress; script execution was not demonstrated.Show less

ClipBucket v5 through 5.5.3-#206 contains a reflected cross-site scripting vulnerability in admin_area/index.php that allows attackers to inject HTML via the val parameter in mode=add_todo. Attackers can lure a logged-in administrator into submitting a cross-site POST form without CSRF protection, executing script in the admin panel origin.Show less

ClipBucket v5 through 5.5.3-#206 contains a reflected cross-site scripting vulnerability in admin_area/language_settings.php via the unencoded edit_language GET parameter. Attackers can send administrators with basic_settings permission a crafted link whose payload is echoed into a hidden input, executing script in the admin panel origin.Show less

ClipBucket v5 through 5.5.3-#206 contains a reflected cross-site scripting vulnerability in admin_area/flagged_item.php via the unencoded type GET parameter. Attackers can send crafted flagged_item.php?type= links to logged-in administrators or moderators to execute injected script in the admin panel origin.Show less

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in axew3.com WP w3all phpBB wp-w3all-phpbb-integration allows Stored XSS.This issue affects WP w3all phpBB: from n/a through 3.1.0.Show less

The public consent endpoint of JTL-Shop accepts arbitrary consent names from unauthenticated visitors without validating them against the configured consent items. These names are stored in the consent statistics and rendered without output encoding in the administration backend. An unauthenticated remote attacker can thereby inject script code that is executed in the browser session of an administrator viewing the consent statistics page, allowing actions to be performed with the administrator's privileges.Show less

The Gallery Custom Links plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'display_name (profile.php) + comment (wp-comments-post.php)' parameter in all versions up to, and including, 2.3.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit requires two coordinated inputs from the same authenticated attacker: an HTML comment payload stored in a comment body (preserved verbatim by WordPress comment kses) and a matching simple_html_dom noise key placed in the attacker's display_name (which survives esc_attr() intact), with substitution occurring after both filters have run during the plugin's default-on output-buffering pass over the full rendered page.Show less
