Descrição técnica

The All-In-One Security (AIOS) – Security and Firewall plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 5.4.7. This is due to insufficient input sanitization in the get_rest_route() function and missing output escaping in the column_default() method of the debug log list table. When the 'Disable REST API for non-logged in users' feature (aiowps_disallow_unauthorized_rest_requests) is enabled alongside debug logging (aiowps_enable_debug), an unauthenticated attacker can embed arbitrary HTML or JavaScript in the REST request path. The path is retrieved via urldecode($_SERVER['REQUEST_URI']), which decodes URL-encoded payloads into literal HTML characters. This decoded, unsanitized value is concatenated directly into a debug log message and stored in the database. When an administrator navigates to the AIOS Dashboard Debug Logs page, the column_default() method returns the raw database value without escaping, and the parent list table echoes it directly, causing JavaScript execution in the administrator's browser session. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views the debug log page, enabling nonce theft, privileged AJAX/REST actions, and potential full site compromise.

———Akaunting 3.3.0 contains a stored cross-site scripting vulnerability in the XLSX invoice-import workflow. An authenticated Manager can import a child invoice whose invoice number contains HTML and is linked to a recurring invoice. When a victim opens that recurring invoice, Akaunting raw-renders the stored child number in an anchor, causing attacker-controlled markup to execute in the victim's browser.6h CVE-2026-1272035.4 MÉD

———AppFlowy Cloud through 0.9.64 contains a stored cross-site scripting vulnerability that allows authenticated workspace members to upload blobs with unvalidated Content-Type values that are later served inline without a Content-Disposition header or authentication on the retrieval route. Attackers can upload a text/html or image/svg+xml blob via put_blob_handler, which is then rendered as an active same-origin document through the unauthenticated get_blob_handler endpoint and cached immutably for one year, enabling persistent script execution against any visitor who accesses the URL.7h CVE-2026-1246987.1 ALT

———In Progress Kendo UI for jQuery, the Chart default tooltip renders point values as raw HTML. An attacker who can influence a string point value can inject markup that executes as JavaScript when a user hovers over the point. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. Version 2016.2.607 or earlier may be affected, but earlier releases have not been verified. The latest vulnerable version is 2026.3.1015; the issue is fixed in version 2026.4.1111.7h CVE-2026-1246977.1 ALT

———In Progress Kendo UI for jQuery, Chart shared-tooltip rendering treats bound category and series-name values as raw HTML. An attacker who can influence values consumed by an affected Chart can inject markup that executes as JavaScript when a user displays the shared tooltip. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. Version 2016.2.607 or earlier may be affected, but earlier releases have not been verified. The latest vulnerable version is 2026.3.1015; the issue is fixed in version 2026.4.1111.7h CVE-2026-1246967.1 ALT

———In Progress Kendo UI for jQuery, Spreadsheet sheet names are inserted into the SheetsBar menu button's data-sheet-name attribute without encoding. An attacker who can influence a sheet name can inject an event-handler attribute and execute JavaScript when a user hovers over the menu button. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. The first affected version is 2024.4.1112; the latest vulnerable version is 2026.3.1015. The issue is fixed in version 2026.4.1111.7h CVE-2026-1246957.1 ALT

———In Progress Kendo UI for jQuery Form, the items[].hint option is documented as a string but is rendered as HTML. An attacker who can influence a Form item's hint can cause attacker-controlled markup to execute as JavaScript when a user views the rendered form. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. The first affected version is 2020.2.513; the latest vulnerable version is 2026.3.1015. The issue is fixed in version 2026.4.1111.7h
