The PGS Core plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 5.8.0 via deserialization of untrusted input in the 'import_header' function. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
#TESTING

Software has bugs, and catching bugs can involve lots of effort. This book addresses this problem by automating software testing, specifically by generating tests automatically. Recent years have seen the development of novel techniques that lead to dramatic improvements in test generation and software testing. They now are mature enough to be assembled in a book – even with executable code.
