CVE-2025-0855 is a critical PHP Object Injection vulnerability affecting all versions of the PGS Core plugin for WordPress up to and including 5.8.0. This flaw allows unauthenticated attackers to inject a PHP Object through the 'import_header' function due to insecure deserialization. The vulnerability carries a CVSS score of 9.8 (Critical), indicating a high potential for compromise of confidentiality, integrity, and availability, with low attack complexity and no user interaction required. While no known POP chain exists in the plugin itself, if one is present via other installed software, it could lead to arbitrary file deletion, sensitive data retrieval, or remote code execution. Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), and it is not listed in CISA's KEV catalog, suggesting no active exploitation. However, the vulnerability has garnered significant community discussion with 10 mentions, placing it in the top 1% of CVEs for community attention.
