The function \"hmwp_get_user_ip\" tries to retrieve the IP address from multiple headers, including IP address headers that the user can spoof, such as \"X-Forwarded-For.\" As a result, the malicious payload supplied in one of these IP address headers will be directly inserted into the SQL query, making SQL injection possible.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-89"],"references":["https://codecanyon.net/item/hide-my-wp-amazing-security-plugin-for-wordpress/4177158","https://patchstack.com/database/vulnerability/hide-my-wp/wordpress-hide-my-wp-premium-plugin-6-2-3-sql-injection-sqli-vulnerability","https://patchstack.com/hide-my-wp-vulnerabilities-fixed/","https://codecanyon.net/item/hide-my-wp-amazing-security-plugin-for-wordpress/4177158","https://patchstack.com/database/vulnerability/hide-my-wp/wordpress-hide-my-wp-premium-plugin-6-2-3-sql-injection-sqli-vulnerability"],"products":["wpwave:hide_my_wp"],"source":"nvd","synced_at":"2026-10-19T21:25:41.256909649+00:00"},"epss":{"cve":"CVE-2021-36916","score":0.01861,"percentile":0.79249,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
