DESCRIPTION:
mermenomachus has discovered two vulnerabilities in the Link Library
plugin for WordPress, which can be exploited by malicious people to
conduct cross-site scripting and SQL injection attacks.

1) Input passed via the "id" parameter to
wp-content/plugins/link-library/tracker.php is not properly sanitised
before being returned to the user. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.

2) Input passed via the "id" parameter to
wp-content/plugins/link-library/tracker.php is not properly sanitised
before being used in SQL queries. This can be exploited to manipulate
SQL queries by injecting arbitrary SQL code.

The vulnerabilities are confirmed in version 5.0.8. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
