The WPeMatico RSS Feed Fetcher plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.9 This is due to the plugin removing WordPress's wpfilterpostkses filter from contentsavepre immediately before calling wpinsertpost() with RSS feed content, whenever the campaign's last editor had the unfilteredhtml capability — a flag the plugin sets automatically for every admin-saved campaign. Imported item content is taken raw from $item->getcontent(), only entity-decoded, and stored verbatim in postcontent. This makes it possible for unauthenticated attackers, who publish or compromise an RSS feed that an administrator has subscribed a WPeMatico campaign to, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected imported post.
The WPeMatico RSS Feed Fetcher WordPress plugin before 2.8.27 does not perform a capability check before fetching a user-supplied URL and rendering the response, allowing users with contributor-level access and above to force the server to issue requests to internal-only hosts and read the responses back.
The WPeMatico RSS Feed Fetcher WordPress plugin before 2.8.26 does not verify ownership or authorization before returning a campaign's stored configuration and run log, allowing users with contributor-level access and above to read the configuration and execution logs of campaigns created by other users, including administrators.
