Last modified Jun 17, 2026

CVE-2021-25082 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. The Popup Builder WordPress plugin before 4.0.7 does not validate and sanitise the sgpb_type parameter before using it in a require statement, leading to a Local File Inclusion issue. Furthermore, since the beginning of the string can be controlled, the issue can lead to RCE vulnerability via wrappers such as PHAR. EPSS estimates a 5.37% chance of exploitation in the next 30 days.
