The flaw occurs in the OpenAPI preview error view, allowing an attacker to execute arbitrary scripts in the context of the affected application. This vulnerability has been assigned CVE-2026-123301 and is rated high severity with a CVSS score of 8.2. The issue is fixed in version 2026.3.

In JetBrains Datalore before 2026.4 stored XSS in notebook charts was possible via Vega editor link

The Wp Parsidate plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the calendar Gutenberg block's 'theme' attribute in versions up to, and including, 6.4. This is due to insufficient input sanitization and output escaping on the block attribute value which is concatenated directly into an HTML class attribute in the printCalendar() function without esc_attr(). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The MDTF – Meta Data and Taxonomies Filter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'vars' parameter in all versions up to, and including, 1.4.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires that a published page or post on the target site contains the [meta_data_filter_results] shortcode, which is the primary output feature of the plugin.

The WP User Manager – Registration Form, Login Form, User Profile Builder & Member Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'name (REST users endpoint) -> wp_users.display_name' parameter in all versions up to, and including, 2.10.2 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 payload is stored via the WordPress core REST endpoint POST /wp-json/wp/v2/users/me, which bypasses the plugin's own wpum_sanitize_text sanitizer applied on its front-end account form, making the save-time sanitization ineffective as a mitigation.

The Permalink Manager Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'slug' parameter in all versions up to, and including, 2.6.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. An Author-level attacker can submit a percent-encoded HTML/JavaScript payload as a post slug via the REST API, which survives sanitization intact and executes in an administrator's browser session when the URI Editor admin page is loaded.

The Posts Table with Search & Sort plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'date_format' parameter in all versions up to, and including, 1.4.14 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload bypasses wp_kses_post at save time because it contains no literal angle bracket characters; the malicious HTML tags are only reconstructed at render time, making this exploitable by Contributors who would ordinarily lack the unfiltered_html capability.

The Graphina – Charts and Graphs For Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'iq_tree_chart_node_font_family (and any text control serialized into chart_data['settings'])' parameter in all versions up to, and including, 3.1.13 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Elementor's Utils::kses_post_deep() does not strip the attack payload on save because the payload contains no disallowed HTML tags — only a single quote and an event-handler fragment — allowing the malicious value to survive persistence.

The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'badge' parameter in all versions up to, and including, 1.2.80 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit is particularly effective against higher-privileged users — such as editors and administrators — who preview a Contributor's pending post containing the malicious shortcode.

CVE-2026-19876 is a reflected cross-site scripting (XSS) vulnerability in the login/SSO error page of INFINITT ULite versions up to 5.0.2.1_BN48_20260528. It allows unauthenticated remote attackers to execute arbitrary JavaScript in the browser of victims who open a crafted link. The vulnerability is due to an unsanitized request parameter that is reflected without proper output encoding. This flaw is fixed in version 5.0.2.1_BN50.

CVE-2026-65022 is a cross-site scripting (XSS) vulnerability in HCLSoftware BigFix MCM & Mobile versions up to 3.7. The vulnerability arises because the MDM App Catalog / App Store preview does not properly sanitize or encode user-supplied HTML before rendering it. This allows an attacker to inject malicious HTML that can be executed when users view the preview and interact with the crafted content.

A stored cross-site scripting (XSS) vulnerability exists in LY Corporation's Armeria versions 0.80.0 through 1.42.0. The flaw occurs when directory listing is enabled and attackers control file names, allowing malicious scripts to be stored and executed when a user views the directory listing. This issue is fixed in version 1.43.0.

The MDJM Event Management and Mobile Events Manager WordPress plugins through 1.7.8.7 do not check a capability or a nonce before creating a WordPress role from a name supplied in the request, and store that name without escaping it, allowing any authenticated user, such as a subscriber, to inject arbitrary web scripts which execute when an administrator opens one of the standard user management screens.

The Anti-Spam, Spam FireWall by CleanTalk WordPress plugin before 6.91 does not escape a commenter-supplied value before outputting it on an administrative spam-review screen, allowing unauthenticated users to inject arbitrary web scripts that execute in the browser of an administrator who reviews flagged comments.

The Advanced Custom Fields (ACF®) WordPress plugin before 6.8.11 does not properly sanitize a stored field definition that can be modified through its comment handling, allowing unauthenticated users to inject a payload that is emitted as an HTML attribute name and executed as JavaScript in the browser of any visitor or administrator who views a page rendering the affected field.

The ShopEngine Gutenberg WooCommerce Builder Blocks Addon WordPress plugin before 2.4.4 does not validate the user's capabilities or the ownership of the targeted post in one of its AJAX actions, and does not escape the stored value before outputting it in a JavaScript context, allowing users with a role as low as contributor to inject arbitrary scripts into any post that will run when a higher privileged user edits it.

The iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more WordPress plugin before 3.13.7 does not properly escape content it re-emits through its bundled HTML parser, allowing unauthenticated users to inject arbitrary web scripts in pages that will execute in the session of any visitor viewing them, including logged in administrators.

The All-in-One Video Gallery WordPress plugin before 5.1.0 does not escape a video's stored thumbnail URL before outputting it in the admin video list, and does not sanitise that value when it is written outside its own editor, allowing users with a role as low as Subscriber to perform Stored Cross-Site Scripting attacks against administrators.

The GutenKit WordPress plugin before 2.5.5 does not properly sanitize custom CSS saved against a post before printing it inside an inline style block on the published page, allowing users with the Author role and above to break out of the style element and store JavaScript that executes in the browser of any visitor who views the post. Exploitation affects sites running WordPress below 7.0.
