- CVE-2026-100152, 3 Oct 2026
- The The All in One SEO - AI SEO Plugin to Boost SEO Rankings & Traffic (Schema, Local SEO, Sitemap & SEO Insights) plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 5.0.2 This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. This requires the AIOSEO breadcrumb to be rendered on the search results page via the block, widget, shortcode, or template tag. CVE record
- CVE-2026-19856, 2 Oct 2026
- The All in One SEO WordPress plugin before 5.0.2.1 does not correctly determine which shortcodes are present in content derived from user input before deciding which ones to strip, allowing unauthenticated users to execute arbitrary shortcodes registered on the site. On sites upgraded from older versions the protection is disabled outright, making the issue reachable without any crafted input. CVE record
- CVE-2026-85492, 2 Oct 2026
- The All in One SEO - AI SEO Plugin to Boost SEO Rankings & Traffic (Schema, Local SEO, Sitemap & SEO Insights) plugin for WordPress is vulnerable to DOM-Based Cross-Site Scripting via URL Pathname in all versions up to, and including, 5.0.1.1 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 visits a crafted URL. Exploitation requires the victim to hold the aioseo_manage_seo capability and to open the SEO Preview panel in the WordPress admin toolbar while visiting a page with a malicious payload embedded in the URL pathname. CVE record
- CVE-2026-82884, 2 Sep 2026
- The All in One SEO WordPress plugin before 5.0.0.1 does not sanitise and escape some content stored in posts before rendering it back in the post editor, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks that trigger when a higher privileged user edits the post. CVE record
- CVE-2026-10755, 20 Jul 2026
- The All in One SEO WordPress plugin before 4.9.9 does not correctly restrict access to some of its AI integration REST API endpoints, allowing users with low-level privileges such as Contributors to overwrite or reset the site-wide AI integration state. CVE record
- CVE-2026-5075, 20 May 2026
- The All in One SEO plugin for WordPress is vulnerable to Sensitive Information Exposure via 'internalOptions' localized script data in versions up to, and including, 4.9.7 due to sensitive internal option data being passed to wp_localize_script() in post editor contexts without effective masking for low-privilege users. This makes it possible for authenticated attackers, with contributor-level access and above, to view configured API/OAuth tokens and license-related values from page source. CVE record
- CVE-2025-14384, 16 Jan 2026
- The All in One SEO - Powerful SEO Plugin to Boost SEO Rankings & Increase Traffic plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the `/aioseo/v1/ai/credits` REST route in all versions up to, and including, 4.9.2. This makes it possible for authenticated attackers, with Contributor-level access and above, to disclose the global AI access token. CVE record
- CVE-2025-12847, 15 Nov 2025
- The All in One SEO - Powerful SEO Plugin to Boost SEO Rankings & Increase Traffic plugin for WordPress is vulnerable to unauthorized arbitrary media attachment deletion due to a missing authorization check in all versions up to, and including, 4.8.9. This is due to the REST API endpoint `/wp-json/aioseo/v1/ai/image-generator` only verifying that users have the `edit_posts` capability (Contributors and above) without checking if they own or have permission to delete the specific media attachments. This makes it possible for authenticated attackers, with Contributor-level access and above, to permanently delete arbitrary media attachments by ID via the REST API, granted they can determine valid attachment IDs. CVE record
- CVE-2024-3368, 20 May 2024
- The All in One SEO WordPress plugin before 4.6.1.1 does not validate and escape some of its Post fields before outputting them back, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks CVE record

- The All in One SEO Pack plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple parameters in versions up to, and including, 4.2.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with Administrator role or above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
- CVE-2023-0586, 24 Feb 2023
- The All in One SEO Pack plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple parameters in versions up to, and including, 4.2.9 due to insufficient input sanitization and output escaping.
