The ManageWP Worker WordPress plugin before 4.9.37 does not bind the account being logged in to the signature which authorises the login, nor prevent an already used login link from being replayed, allowing attackers who obtain such a link to gain a session as any user on the site, including an administrator.

Unauthenticated Cross Site Scripting (XSS) in ManageWP Worker <= 4.9.31 versions.

The ManageWP Worker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'MWP-Key-Name' HTTP request header in all versions up to, and including, 4.9.31. This is due to insufficient input sanitization and output escaping of attacker-controlled header values. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrator visits the plugin's connection management page with debug parameters.

The Broken Link Checker WordPress plugin before 2.4.2 does not validate a the link URLs before making a request to them, which could allow admin users to perform SSRF attack, for example on a multisite installation.

Unauth. SQL Injection (SQLi) vulnerability in MainWP MainWP Broken Links Checker Extension plugin <= 4.0 versions.

A vulnerability was found in Broken Link Checker Plugin up to 1.10.1 on WordPress. It has been declared as problematic. Affected by this vulnerability is the function optionspage of the file core/core.php of the component Settings Page. The manipulation of the argument exclusionlist/blccustomfields leads to cross site scripting. The attack can be launched remotely. Upgrading to version 1.10.2 is able to address this issue. The patch is named 90615fe9b0b6f9e6fb254d503c302e53a202e561. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-230659.

The Broken Link Checker WordPress plugin before 1.11.20 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed (for example in multisite setup)

The Broken Link Checker plugin for WordPress is vulnerable to deserialization of untrusted input via the '$logfile' value in versions up to, and including 1.11.16. This makes it possible for authenticated attackers with administrative privileges and above to call files using a PHAR wrapper that will deserialize the data and call arbitrary PHP Objects that can be used to perform a variety of malicious actions granted a POP chain is also present. It also requires that the attacker is successful in uploading a file with the serialized payload.

A reflected XSS vulnerability was found in includes/admin/table-printer.php in the broken-link-checker (aka Broken Link Checker) plugin 1.11.8 for WordPress. This allows unauthorized users to inject client-side JavaScript into an admin-only WordPress page via the wp-admin/tools.php?page=view-broken-links sfilter parameter in a search action.

The broken-link-checker plugin through 1.11.8 for WordPress (aka Broken Link Checker) is susceptible to Reflected XSS due to improper encoding and insertion of an HTTP GET parameter into HTML. The filter function on the page listing all detected broken links can be exploited by providing an XSS payload in the sfilter GET parameter in a filterid=search request. NOTE: this is an end-of-life product.
