Cookie Banner for GDPR / CCPA <= 4.3.5 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'regionArray' Parameter
Noroxi assessment
Priority: Monitor (action score 28/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.42% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- No fixed version is recorded, but the references include a patch (commit or PR) link.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. See the fix and affected versions sections below.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
The Cookie Banner for GDPR / CCPA – WPLP Cookie Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'regionArray' parameter in all versions up to, and including, 4.3.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires that the site administrator has enabled the 'Support Google Consent Mode (GCM)' setting, which is disabled by default. Additionally, the AJAX handler performs no nonce or capability check, allowing any authenticated user including those with Subscriber-level access to overwrite the affected plugin setting.
