Green Popups WordPress plugin: Blind SQL injection
Summary
The Green Popups plugin for WordPress, a popup builder, contains a blind SQL injection vulnerability (CWE-89) in versions before 7.6.3. According to the CVSS vector, an attacker can read and modify database contents over the network without user interaction, which may expose customer or form data. The required privileges are disputed: the CVSS vector says none are needed, while VulDB lists login as required.
Affected
- Green Popups (WordPress plugin) versions before 7.6.3
- Earliest affected version: unknown (lower bound listed as n/a)
Fixed in
- Version 7.6.3 or later (released by halfdata on GitHub on 21 Sep 2026)
Workaround
- Unknown. No vendor-published workaround found. Updating to 7.6.3 or later is the recommended fix.
Exploitation
- No known exploitation in the wild; CISA KEV flag: No (per one tracker).
- No public proof-of-concept found in the sources checked; search coverage was limited.
- CISA SSVC: exploitation none, automatable yes, technical impact partial.
- EPSS 0.00236 (low predicted exploitation probability).
Our recommendation
- Identify all WordPress sites running Green Popups and check the installed version.
- Update Green Popups to 7.6.3 or later; treat sites on older versions as potentially compromised until reviewed.
- Review web server and database logs for unusual requests to plugin endpoints and check form-related tables for unexpected changes.
- Check the Patchstack advisory and NVD for updates on authentication requirements and proof-of-concept code.
