Summary
The Alba Board plugin for WordPress up to version 2.1.3 has an authorization bypass vulnerability – it does not properly verify user permissions. Authenticated attackers with subscriber-level access can read private alba_card data (title, description, assignee, due date, tags, comments) intended only for Administrators and Editors. Additionally, the handler is registered via wp_ajax_nopriv_ and the nonce is exposed on pages with the [alba_board] shortcode, allowing unauthenticated users to exploit it as well.
Risk Assessment
Unauthorized users (including unauthenticated ones) can access sensitive card data, potentially compromising privacy and information security.
Recommendation
Update the Alba Board plugin to the latest version. If not available, temporarily remove the [alba_board] shortcode from public pages or restrict access to it.

- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
Original NVD description (English source)
The Alba Board plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to access arbitrary private alba_card post data, including title, description, assignee, due date, tags, and comments, that is intended to be restricted to Administrators and Editors. The handler is registered via the wp_ajax_nopriv_ hook and its nonce is exposed to all site visitors through wp_localize_script on pages containing the [alba_board] shortcode, making this exploitable by unauthenticated users who can access any such page.
