- CVE-2026-2433, 7 Mar 2026
- The RSS Aggregator - RSS Import, News Feeds, Feed to Post, and Autoblogging plugin for WordPress is vulnerable to DOM-Based Cross-Site Scripting via postMessage in all versions up to, and including, 5.0.11. This is due to the plugin's admin-shell.js registering a global message event listener without origin validation (missing event.origin check) and directly passing user-controlled URLs to window.open() without URL scheme validation. This makes it possible for unauthenticated attackers to execute arbitrary JavaScript in the context of an authenticated administrator's session by tricking them into visiting a malicious website that sends crafted postMessage payloads to the plugin's admin page. CVE record
- CVE-2026-1216, 17 Feb 2026
- The RSS Aggregator plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'template' parameter in all versions up to, and including, 5.0.10 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. CVE record
- CVE-2025-14745, 23 Jan 2026
- The RSS Aggregator - RSS Import, News Feeds, Feed to Post, and Autoblogging plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wp-rss-aggregator' shortcode in all versions up to, and including, 5.0.10 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 record
- CVE-2025-14375, 16 Jan 2026
- The RSS Aggregator - RSS Import, News Feeds, Feed to Post, and Autoblogging plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘className’ parameter in all versions up to, and including, 5.0.10 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. CVE record
- CVE-2024-9583, 23 Oct 2024
- The RSS Aggregator - RSS Import, News Feeds, Feed to Post, and Autoblogging plugin for WordPress is vulnerable to unauthorized use of functionality due to a missing capability check on the wprss_ajax_send_premium_support function in all versions up to, and including, 4.23.12. This makes it possible for authenticated attackers, with Subscriber-level access and above, to send premium support requests with an attacker-controlled subject line and email address to support allowing them to impersonate the site owner. License information may also be leaked. CVE record
- CVE-2024-6621, 16 Jul 2024
- The RSS Aggregator - RSS Import, News Feeds, Feed to Post, and Autoblogging plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'wprss_activate_feed_source' and 'wprss_pause_feed_source' functions in all versions up to, and including, 4.23.11. This makes it possible for authenticated attackers, with Subscriber-level access and above, to activate or pause existing RSS feeds. CVE record
- CVE-2024-0628, 7 Feb 2024
- The WP RSS Aggregator plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 4.23.5 via the RSS feed source in admin settings. This makes it possible for authenticated attackers, with administrator-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. CVE record
- CVE-2024-0630, 5 Feb 2024
- The WP RSS Aggregator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the RSS feed source in all versions up to, and including, 4.23.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled. CVE record
- CVE-2022-0189, 28 Feb 2022
- The WP RSS Aggregator WordPress plugin before 4.20 does not sanitise and escape the id parameter in the wprss_fetch_items_row_action AJAX action before outputting it back in the response, leading to a Reflected Cross-Site Scripting CVE record
- CVE-2021-24988, 27 Dec 2021
- The WP RSS Aggregator WordPress plugin before 4.19.3 does not sanitise and escape data before outputting it in the System Info admin dashboard, which could lead to a Stored XSS issue due to the wprss_dismiss_addon_notice AJAX action missing authorisation and CSRF checks, allowing any authenticated users, such as subscriber to call it and set a malicious payload in the addon parameter. CVE record
- CVE-2021-24768, 29 Nov 2021
- The WP RSS Aggregator WordPress plugin before 4.19.2 does not properly sanitise and escape the URL to Blacklist field, allowing malicious HTML to be inserted by high privilege users even when the unfiltered_html capability is disallowed, which could lead to Cross-Site Scripting issues. CVE record
