CVE-2023-4521 is a critical remote code execution (RCE) vulnerability affecting the Import XML and RSS Feeds WordPress plugin versions prior to 2.1.5. This flaw stems from the accidental inclusion of a web shell, a remnant of a Proof-of-Concept for a previous issue, which was not removed before release. The vulnerability carries a CVSS score of 9.8 (Critical), indicating it can be exploited by unauthenticated attackers over the network with low complexity, leading to complete compromise of confidentiality, integrity, and availability. Its high EPSS and FAUCET Risk Scores further emphasize the significant threat it poses. While not currently listed on the CISA KEV catalog or Hot List, exploit intelligence shows a Nuclei template is available for unauthenticated RCE, suggesting potential for active exploitation. Despite this, there is no public Metasploit module or ExploitDB entry, and community discussion and media coverage remain minimal.
