|---|---|---|---|---|---|---|---|
| CVE-2026-44549 | Hig | 0.47 | 7.3 | 0.00 | May 15, 2026 | Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.8.0, Excel file attachments are previewed in an unsafe way. A crafted XLSX file payload can be used to cause the sheetjs function sheet_to_html to embed an XSS payload into the generated HTML. This is subsequently added to the DOM unsanitized via @html causing the payload to trigger. This vulnerability is fixed in 0.8.0. | |
| CVE-2026-44721 | Hig | 0.47 | 7.3 | 0.00 | May 15, 2026 | Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, a stored cross-site scripting (XSS) vulnerability that allows any authenticated user with model creation permission (workspace.models) to execute arbitrary JavaScript in the browser of any other user (including admins) who views the malicious model in the chat UI. This vulnerability is fixed in 0.9.0. | |
| CVE-2021-47963 | Hig | 0.47 | 7.2 | 0.00 | May 15, 2026 | Anote 1.0 contains a persistent cross-site scripting vulnerability that allows attackers to execute arbitrary code by injecting malicious payloads into markdown files stored within the application. Attackers can craft malicious markdown files with embedded JavaScript that executes system commands when opened, enabling remote code execution on the victim's computer. | |
| CVE-2026-3718 | Hig | 0.47 | 7.2 | 0.00 | May 14, 2026 | The ManageWP Worker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'MWP-Key-Name' HTTP request header in all versions up to, and including, 4.9.31. This is due to insufficient input sanitization and output escaping of attacker-controlled header values. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrator visits the plugin's connection management page with debug parameters. | |
| CVE-2020-37222 | Hig | 0.47 | 7.2 | 0.00 | May 13, 2026 | Kuicms Php EE 2.0 contains a persistent cross-site scripting vulnerability that allows unauthenticated attackers to inject malicious scripts by submitting crafted content through the bbs reply endpoint. Attackers can send POST requests to /web/?c=bbs&a=reply with HTML and JavaScript payloads in the content parameter to execute arbitrary scripts in users' browsers. | |
| CVE-2026-6177 | Hig | 0.47 | 7.2 | 0.00 | May 13, 2026 | The Custom Twitter Feeds plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 2.5.4. This is due to insufficient output escaping in the CTF_Display_Elements::get_post_text() function when rendering cached tweet text. The plugin's ctf_get_more_posts AJAX action is available to unauthenticated users and directly outputs cached tweet data through nl2br() without HTML escaping. When an attacker can get malicious content into cached tweet data (either by tweeting content that gets cached by the site's feed configuration, or through other vulnerabilities), the malicious HTML/JavaScript is executed when the unauthenticated endpoint is accessed. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses the affected endpoint. | |
| CVE-2026-43939 | Hig | 0.47 | 7.3 | 0.00 | May 12, 2026 | YetAnotherForum.NET (YAF.NET) is a C# ASP.NET forum. Prior to 4.0.5 and 3.2.12, the thread posting and reply feature accepts user-supplied content via a a post or reply that is stored server-side and later rendered back into the thread page without adequate HTML sanitization or contextual output encoding. This vulnerability is fixed in 4.0.5 and 3.2.12. | |
| CVE-2026-33862 | Hig | 0.47 | 7.3 | 0.00 | May 12, 2026 | A vulnerability has been identified in Teamcenter V2312 (All versions < V2312.0014), Teamcenter V2406 (All versions < V2406.0012), Teamcenter V2412 (All versions < V2412.0009), Teamcenter V2506 (All versions < V2506.0005), Teamcenter V2512 (All versions). The affected application does not properly encode or filter user-supplied data. This could allow an attacker to inject malicious code that can be executed by other users when they visit the affected page. | |
| CVE-2026-6690 | Hig | 0.47 | 7.2 | 0.00 | May 12, 2026 | The LifePress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'n' parameter of the lp_update_mds AJAX action in all versions up to, and including, 2.2.2. This is due to the `wp_ajax_nopriv_lp_update_mds` action being registered without nonce verification or capability checks, combined with insufficient input sanitization and output escaping when the series name is rendered in the admin settings page. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. | |
| CVE-2026-43887 | Hig | 0.47 | 7.3 | 0.00 | May 11, 2026 | Outline is a service that allows for collaborative documentation. From 0.84.0 to 1.6.1, the Outline comment section permits users to mention other users; however, the backend does not validate or sanitize the href attribute associated with these mentions. As a result, potentially dangerous protocols (e.g., javascript:) are not filtered, introducing a risk of client-side code execution. This vulnerability is fixed in 1.7.0. | |
| CVE-2025-61314 | Hig | 0.47 | 7.3 | 0.00 | May 11, 2026 | A reflected cross-site scripted (XSS) vulnerability in the dfm-menu_orderopt.php component of GmbH Mecury Managed Print Services (docuForm) v11.11c allows attackers to execute arbitrary Javascript in the context of a user's browser via injecting a crafted payload into an unfiltered variable value. | |
| CVE-2025-61313 | Hig | 0.47 | 7.3 | 0.00 | May 11, 2026 | A reflected cross-site scripted (XSS) vulnerability in the dfm-menu_markeralerts.php component of GmbH Mecury Managed Print Services (docuForm) v11.11c allows attackers to execute arbitrary Javascript in the context of a user's browser via injecting a crafted payload into an unfiltered variable value. | |
| CVE-2025-61312 | Hig | 0.47 | 7.3 | 0.00 | May 11, 2026 | A reflected cross-site scripted (XSS) vulnerability in the acc-menu_pricess.php component of GmbH Mecury Managed Print Services (docuForm) v11.11c allows attackers to execute arbitrary Javascript in the context of a user's browser via injecting a crafted payload into an unfiltered variable value. | |
| CVE-2025-61311 | Hig | 0.47 | 7.3 | 0.00 | May 11, 2026 | A reflected cross-site scripted (XSS) vulnerability in the dfm-menu_alerts.php component of GmbH Mecury Managed Print Services (docuForm) v11.11c allows attackers to execute arbitrary Javascript in the context of a user's browser via injecting a crafted payload into an unfiltered variable value. | |
| CVE-2026-7330 | Hig | 0.47 | 7.2 | 0.00 | May 8, 2026 | The Auto Affiliate Links plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 6.8.8 This is due to insufficient input sanitization on the 'url' POST parameter in the aal_url_stats_save_action() function and a complete absence of output escaping in aal_display_clicks(), where the stored value is echoed directly into an anchor element's href attribute and inner text without esc_url(), esc_attr(), or esc_html(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts into the admin statistics page that execute in an administrator's browser when the page is visited, leveraging a publicly exposed nonce and an unauthenticated AJAX endpoint registered via the wp_ajax_nopriv_ hook. | |
| CVE-2026-44742 | Hig | 0.47 | 7.2 | 0.00 | May 7, 2026 | Postorius through 1.3.13 does not escape HTML in the message subject when rendering it in the Held messages pop-up, as exploited in the wild in May 2026. | |
| CVE-2026-7332 | Hig | 0.47 | 7.2 | 0.00 | May 6, 2026 | The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'booking_form_page_url' parameter in all versions up to, and including, 5.5.0 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. The malicious activity log entry is written to the database even when Stripe is not configured, because the latepoint_order_intent_created action hook fires before the Stripe Connect account ID is validated, meaning a fully functional Stripe integration is not required for exploitation. | |
| CVE-2026-23928 | Hig | 0.47 | — | 0.00 | May 6, 2026 | The Item history widget (in Zabbix 7.0+) or the Plain text widget (in Zabbix 6.0) can execute injected JavaScript when HTML display is enabled. This can allow an attacker to perform unauthorized actions depending on which user opens a dashboard containing these widgets. The malicious JavaScript would have to come from a monitored host controlled by the attacker. Note: the Item history widget is a replacement for the Plain text widget since Zabbix 7.0. | |
| CVE-2026-23926 | Hig | 0.47 | — | 0.00 | May 6, 2026 | An authenticated (non-super) administrator can create a maintenance period with a JavaScript payload that is executed by any user that opens tooltip for that maintenance period in the Host navigator widget. This can allow the attacker to perform unauthorized actions depending on which user opens the tooltip. | |
| CVE-2026-4803 | Hig | 0.47 | 7.2 | 0.00 | May 5, 2026 | The Royal Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'status' parameter in the wpr_update_form_action_meta AJAX action in all versions up to, and including, 1.7.1056. This is due to insufficient input sanitization and output escaping, combined with a publicly leaked nonce that allows unauthenticated access to the AJAX handler. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. |
