Cookie consent and privacy-compliance plugins are deceptively security-sensitive because they sit at the intersection of front-end script execution, visitor consent state, and site-wide configuration. They often manage banner templates, block or release third-party scripts, generate legal documents, and store consent-related settings and logs — which means weaknesses can translate into stored/reflected XSS in banners or documents, CSRF-driven configuration changes (silently altering consent behavior), data leakage via misprotected endpoints, or integrity issues in the rules that decide when scripts are allowed to run. Complianz – GDPR/CCPA Cookie Consent version 7.4.4.2 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64617, confirming that the plugin was reviewed from a secure code perspective with attention to the most common exploitation paths for privacy, cookie, and consent-management plugins.
| Name of | Complianz – GDPR/CCPA Cookie Consent |
| Version | 7.4.4.2 |
| Active installations | 1+ million |
| Description | Complianz is a GDPR/CCPA Cookie Banner plugin with a conditional Cookie Consent Banner and a customized Cookie Policy based on the results of the built-in Cookie Scan. |
| Security | Successfully tested for: SQL Injection (SQLi) Cross-Site Scripting (XSS) – Stored & Reflected Cross-Site Request Forgery (CSRF) Authentication Vulnerabilities Authentication Bypass Exploits Privilege Escalation Buffer Overflow Denial-of-Service (DoS) vectors Data Leakage Vulnerabilities Insecure Dependency Usage Remote Code Execution (RCE) Risks Unauthorized File Access Insufficient Injection Protection Information Disclosure via Misconfigured Endpoints |
| CleanTalk Certification | Proudly earned the “Plugin Security Certification” (PSC) from CleanTalk, indicating adherence to stringent security standards. |
| Additional Information | Site owners can implement cookie consent workflows with the assurance of the “Plugin Security Certification” (PSC). As a best practice, limit access to consent configuration to trusted administrators, review script-blocking rules after theme/plugin changes, and periodically audit which integrations are allowed to execute after consent. |

Key Features
Complianz – GDPR/CCPA Cookie Consent is built around a guided compliance workflow that combines a configuration wizard with automated discovery and enforcement. It provides region-aware cookie consent banners, allowing site owners to tailor consent behavior to different legal frameworks, and it supports customizable templates and styling controls so the banner can be aligned with site UX requirements. A central capability is the cookie scan, which is used to inform a customized cookie policy and to keep consent disclosures aligned with what the site actually loads over time. On the enforcement side, the plugin can block third-party scripts and embeds (e.g., maps, video iframes, social widgets, analytics tags) until consent is obtained, and it offers a script center for fine-grained control of scripts, services, and categories. From a security perspective, these features matter because they interact with front-end rendering, dynamic script injection/release, admin configuration screens, and integration logic that touches other plugins and services — all of which require strict capability checks, robust request integrity protections, and safe output handling.
Security Assurance
The CleanTalk Plugin Security Certification evaluation for consent-management plugins focuses on attacker models that target configuration integrity and injection surfaces. Common abuse patterns include attempts to inject JavaScript into banner templates, policy content, placeholders, or “service descriptions” (stored XSS), forcing configuration changes via CSRF against administrators (e.g., altering consent categories, enabling/disabling blocking behavior, changing integrations), reading sensitive integration metadata or scan outputs through misprotected AJAX/REST-style endpoints, or exploiting inconsistent role checks to grant lower-privileged users access to global privacy settings. The review validates that state-changing actions are protected with nonces/CSRF defenses, that access control is enforced consistently at the handler level (not just via menu visibility), that data reaching database queries is handled safely, and that any user-controlled values that can be rendered in admin or front-end contexts are output-encoded appropriately. Because consent plugins can influence which scripts execute on the site, the review also considers misconfiguration and leakage vectors (overly verbose diagnostics, predictable endpoints, unsafe parameter handling) that could expose privacy-related data or weaken the intended blocking model.
The plugin has been successfully tested for:
✅ Information Leakage Vulnerabilities
✅ SQL Injection Vulnerabilities
✅ Cross-Site Scripting (XSS) Attacks
✅ Cross-Site Request Forgery (CSRF) Attacks
✅ Authentication & Authentication Bypass Vulnerabilities
✅ Privilege Escalation Vulnerabilities
✅ Buffer Overflow Vulnerabilities
✅ Denial-of-Service (DoS) Vulnerabilities
✅ Data Leakage Vulnerabilities
✅ Insecure Dependencies
✅ Code Execution Vulnerabilities
✅ File Unauthorized Access Vulnerabilities
✅ Insufficient Injection Protection
Conclusion
With PSC-2026-64617, Complianz – GDPR/CCPA Cookie Consent version 7.4.4.2 demonstrates strong baseline security for the workflows that matter most in consent-management plugins: safe administration of global privacy settings, reliable front-end rendering and script-control behavior, and consistent protection against common web vulnerability classes that target templates, endpoints, and configuration handlers. This certification helps site owners reduce risk when implementing consent banners, cookie policies, and script-blocking logic on production websites. As a best practice, keep consent configuration limited to trusted administrators, regularly review integrations after site changes, and treat any editable banner or policy content as security-relevant output that should remain minimal and well-controlled.
