The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to unauthorized settings update due to a missing capability check when updating settings in all versions up to, and including, 4.3.2. This makes it possible for authenticated attackers, with author-level access or above to change the plugin's settings including proxy settings, which are also exposed to authors.

The RSS Aggregator by Feedzy plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.4.2. This is due to missing or incorrect nonce validation on the save_feedzy_post_type_meta() function. This makes it possible for unauthenticated attackers to update post meta via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The RSS Aggregator by Feedzy WordPress plugin before 4.1.1 does not validate and escape some of its block options before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.

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

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.

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.

RSS-aggregator 1.0 does not require administrative authentication for the admin/fonctions/ directory, which allows remote attackers to access admin functions and have unspecified other impact, as demonstrated by (1) an IdFlux request to supprimer_flux.php and (2) a TpsRafraich request to modifier_tps_rafraich.php.

Multiple SQL injection vulnerabilities in RSS-aggregator 1.0 allow remote attackers to execute arbitrary SQL commands via the (1) IdFlux parameter to admin/fonctions/supprimer_flux.php and the (2) IdTag parameter to admin/fonctions/supprimer_tag.php.

PHP remote file inclusion vulnerability in display.php in RSS-aggregator allows remote attackers to execute arbitrary PHP code via a URL in the path parameter. NOTE: some of these details are obtained from third party information.
