5 known CVEsLast CVE: Nov 20, 2024Updated 4mo ago

Risk Assessment

The plugin 'happyforms' v1.26.12 exhibits a mixed security posture. While the static analysis shows good practices like 100% use of prepared statements for SQL queries and a significant number of nonce and capability checks, there are concerning areas. The output escaping is only at 41%, which is a significant weakness and a common indicator for Cross-Site Scripting (XSS) vulnerabilities. The taint analysis revealed three flows with unsanitized paths, which, although not classified as critical or high severity in this specific analysis, represent potential vectors for injection attacks if not properly handled upstream.

The vulnerability history is a significant concern. With 5 known CVEs, all of which are medium severity and related to Improper Neutralization of Input During Web Page Generation (XSS) and Missing Authorization, this indicates a recurring pattern of vulnerabilities that attackers have exploited in the past. The fact that there are no currently unpatched CVEs is positive, but the history of medium severity issues warrants caution. The plugin demonstrates strengths in its handling of database queries and implementing core WordPress security mechanisms, but the significant number of partially unescaped outputs and the historical trend of XSS and authorization flaws suggest potential for vulnerabilities to be introduced or re-emerge.

Overall, while recent versions have addressed known issues, the codebase's output escaping is a persistent concern. The history of medium severity vulnerabilities, particularly XSS and authorization issues, combined with the observed unsanitized taint flows, indicates that users should remain vigilant. While the plugin has a defensible attack surface in terms of entry points, the quality of output sanitization and the historical precedent of certain vulnerability types suggest a medium-to-high risk level until the output escaping is significantly improved.

Key Concerns

Low output escaping percentage
Flows with unsanitized paths
History of medium severity CVEs (XSS, Auth)
