Vulnerabilities

With the aim of informing, warning and helping professionals with the latest security vulnerabilities in technology systems, we have made a database available for users interested in this information, which is in Spanish and includes all of the latest documented and recognised vulnerabilities.

This repository, with over 75,000 registers, is based on the information from the NVD (National Vulnerability Database) – by virtue of a partnership agreement – through which INCIBE translates the included information into Spanish.

On occasions this list will show vulnerabilities that have still not been translated, as they are added while the INCIBE team is still carrying out the translation process. The CVE (Common Vulnerabilities and Exposures) Standard for Information Security Vulnerability Names is used with the aim to support the exchange of information between different tools and databases.

All vulnerabilities collected are linked to different information sources, as well as available patches or solutions provided by manufacturers and developers. It is possible to carry out advanced searches, as there is the option to select different criteria to narrow down the results, some examples being vulnerability types, manufacturers and impact levels, among others.

Through RSS feeds or Newsletters we can be informed daily about the latest vulnerabilities added to the repository. Below there is a list, updated daily, where you can discover the latest vulnerabilities.

CVE-2026-6456

Publication date:

20/05/2026

The Account Switcher plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.0.2. This is due to the `rememberLogin` REST API endpoint using a loose comparison (`!=` instead of `!==`) for secret validation at `app/RestAPI.php:111`, combined with no validation that the secret is non-empty. When a target user has never used the "Remember me" feature, their `asSecret` user meta does not exist, causing `get_user_meta()` to return an empty string. An attacker can send an empty `secret` parameter, which passes the comparison (`&#39;&#39; != &#39;&#39;` is `false`), and the endpoint then calls `wp_set_auth_cookie()` for the target user. Additionally, all REST routes use `permission_callback => &#39;__return_true&#39;` with no capability checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to switch to any user account including Administrator, ultimately granting themselves full administrative privileges.

CVE-2026-6549

Publication date:

20/05/2026

The Logo Manager For Enamad plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &#39;title&#39; attribute of the `vc_enamad_namad`, `vc_enamad_shamed`, and `vc_enamad_custom` shortcodes in all versions up to, and including, 0.7.4 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

CVE-2026-6555

Publication date:

20/05/2026

The ProSolution WP Client plugin for WordPress is vulnerable to Arbitrary File Upload in versions up to, and including, 2.0.0. This is due to an array validation mismatch where only the first file in the upload array undergoes extension and MIME type validation, while all files are processed and uploaded to a web-accessible directory. This makes it possible for unauthenticated attackers to upload malicious PHP files and achieve remote code execution by sending a valid first file followed by a malicious file.

CVE-2026-5293

Publication date:

20/05/2026

The 診断ジェネレータ作成プラグイン (Diagnosis Generator) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &#39;js&#39; parameter in versions up to and including 1.4.16. This is due to missing authorization checks and insufficient input sanitization in the themeFunc() function. The function is hooked to &#39;admin_init&#39; and processes theme update requests without verifying user capabilities, allowing any authenticated user (including subscribers) to save malicious JavaScript to theme files. Additionally, the save() function uses stripslashes() which removes WordPress&#39;s magic quotes protection. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in theme files that will execute whenever a user accesses a page containing the diagnosis form shortcode.

CVE-2026-6072

Publication date:

20/05/2026

The Oliver POS – A WooCommerce Point of Sale (POS) plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to and including 2.4.2.6. The plugin protects its entire /wp-json/pos-bridge/* REST API namespace through the oliver_pos_rest_authentication() permission callback, which uses a loose PHP comparison (==) to compare the attacker-supplied &#39;OliverAuth&#39; header value against the &#39;oliver_pos_authorization_token&#39; option. On fresh installations where the admin has not yet completed the connection flow, this option is unset (get_option returns false). Due to PHP&#39;s type juggling, the loose comparison &#39;0&#39; == false evaluates to true, allowing an unauthenticated attacker to bypass authentication by sending &#39;OliverAuth: 0&#39;. This grants full access to all POS API endpoints, enabling attackers to read user data (including administrator details), update user profiles (including email addresses), and delete non-admin users. An admin account email reset can lead to site takeover.

CVE-2026-6391

Publication date:

20/05/2026

The Sentence To SEO (keywords, description and tags) plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0. This is due to missing or incorrect nonce validation on the create_admin_page() function. This makes it possible for unauthenticated attackers to inject malicious web scripts and update plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

CVE-2026-6394

Publication date:

20/05/2026

The Nexa Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress is vulnerable to Server-Side Request Forgery (SSRF) in versions up to and including 1.1.1. This is due to the import_demo() function accepting a user-supplied URL in the demo_json_file POST parameter and passing it directly to wp_remote_get() without any URL validation or restriction against internal or private network destinations. The nexa_blocks_nonce required for the AJAX action is publicly exposed in the HTML source of any frontend page where the plugin is active via wp_localize_script on the enqueue_block_assets hook, effectively making the nonce available to all visitors and bypassing any intended authentication barrier. This makes it possible for unauthenticated attackers to make server-side HTTP requests to arbitrary internal or external destinations, potentially exposing internal services, cloud metadata endpoints such as the AWS instance metadata service, localhost services, and other resources not intended to be publicly accessible. A secondary SSRF vector also exists whereby image URLs extracted from the attacker-controlled JSON response are subsequently fetched via a second wp_remote_get() call, allowing chained exploitation through a crafted JSON payload.

CVE-2026-6395

Publication date:

20/05/2026

The Word 2 Cash plugin for WordPress is vulnerable to Cross-Site Request Forgery leading to Stored Cross-Site Scripting in versions up to and including 0.9.2. This is due to the complete absence of nonce verification on the settings save handler in the w2c_admin() function, combined with missing input sanitization before storage and missing output escaping when rendering the stored value. The w2c-definitions POST parameter is saved raw via update_option() and later echoed without escaping inside a element. This makes it possible for unauthenticated attackers to forge a request on behalf of a logged-in administrator, storing arbitrary JavaScript payloads that execute in the WordPress admin panel whenever the settings page is visited.

CVE-2026-6397

Publication date:

20/05/2026

The Sticky plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `cvmh-sticky` shortcode `readmoretext` attribute in versions up to and including 2.5.6. This is due to insufficient input sanitization and output escaping in the `cvmh_sticky_front_render()` function — the `readmoretext` attribute value is passed through `apply_filters()` and directly concatenated into the HTML output without any escaping function such as `esc_html()`. 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 a page containing the injected shortcode.

CVE-2026-6399

Publication date:

20/05/2026

The General Options plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 1.1.0. This is due to the use of sanitize_text_field() for output escaping in the Contact Number (ad_contact_number) field — a function that strips HTML tags but does not encode double-quote characters to their HTML entity equivalent (&quot;). When the stored value is echoed inside a double-quoted HTML attribute (value="..."), an attacker-supplied double-quote character breaks out of the attribute context. Even with WordPress&#39;s wp_magic_quotes mechanism (which prefixes quotes with a backslash), the resulting \" sequence is NOT treated as an escaped quote by HTML parsers — the backslash is rendered as a literal character and the bare double-quote still closes the attribute. This makes it possible for authenticated attackers with Administrator-level access and above to inject arbitrary web scripts in the admin settings page that will execute whenever any administrator visits the General Options settings page.

CVE-2026-43617

Publication date:

20/05/2026

Rsync version 3.4.2 and prior contain an authorization bypass vulnerability in the rsync daemon&#39;s hostname-based access control list enforcement when configured with chroot. Attackers can bypass hostname-based deny rules by controlling the PTR record for their source IP address, allowing connections from hostnames that administrators intended to deny when reverse DNS resolution fails and defaults to UNKNOWN.

CVE-2026-43618

Publication date:

20/05/2026

Rsync version 3.4.2 and prior contain an integer overflow vulnerability in the compressed-token decoder where a 32-bit signed counter is not checked for overflow, allowing a malicious sender to trigger an overflow that causes the receiver process to read and return data from outside the intended buffer bounds. Attackers can exploit this vulnerability to disclose process memory contents including environment variables, passwords, heap and stack data, and library memory pointers, significantly reducing ASLR effectiveness and facilitating further exploitation.
