Surbma | GDPR Proof Cookie Consent & Notice Bar Security & Risk Analysis

The "surbma-gdpr-proof-google-analytics" plugin version 17.9.1 exhibits a mixed security posture. On the positive side, the static analysis reveals no identified dangerous functions, no raw SQL queries (all prepared), no file operations, no external HTTP requests, and a commendable lack of direct entry points like AJAX handlers, REST API routes, or shortcodes without proper authentication checks. The presence of capability checks and a small number of total outputs, even with a concerning percentage unescaped, suggests some effort towards security. However, the significantly low percentage of properly escaped output (24%) is a major concern and represents a substantial risk of Cross-Site Scripting (XSS) vulnerabilities.

The vulnerability history shows a past medium-severity XSS vulnerability, which aligns with the findings from the static analysis regarding unescaped output. While there are no currently unpatched CVEs, the pattern of XSS vulnerabilities, coupled with the high rate of unescaped output, indicates a recurring weakness. The bundled Freemius library, while not explicitly flagged as outdated, warrants attention as bundled libraries can introduce vulnerabilities if not maintained. Overall, while the plugin has a small attack surface and avoids common pitfalls like direct SQL injection, the prevalent issue of unescaped output presents a tangible risk that could be exploited by attackers.
