CVE-2021-25114

83
FAUCET Score

CVE-2021-25114 describes a critical SQL injection vulnerability in the Paid Memberships Pro WordPress plugin versions prior to 2.6.7. An unauthenticated attacker can exploit a REST route that fails to properly escape the discount_code parameter, leading to arbitrary SQL execution. This vulnerability carries a CVSS score of 9.8 (Critical), indicating a high potential for complete compromise of confidentiality, integrity, and availability with low attack complexity. While not listed in CISA KEV or Hot List, and with no known Metasploit or ExploitDB modules, Nuclei templates for blind SQL injection exist, and its high EPSS score suggests a significant likelihood of exploitation. Community discussion and media coverage are currently minimal.
