BestWebSoft's Like & Share – Posts, Pages and Widget Social Extension plugin for WordPress Security & Risk Analysis

The 'facebook-button-plugin' version 2.77 exhibits a generally good security posture with a substantial number of code signals indicating robust security practices. The plugin demonstrates strong adherence to output escaping (96%), a high number of nonce checks, and capability checks, which are crucial for protecting against common web vulnerabilities. Furthermore, the taint analysis reveals no critical or high-severity unsanitized flows, and the static analysis shows no unprotected entry points, which are positive indicators.

However, the plugin's vulnerability history is a significant concern. With two known medium-severity CVEs, including 'Exposure of Sensitive Information to an Unauthorized Actor' and 'Cross-site Scripting,' and the most recent one occurring in late 2023, it suggests a recurring pattern of exploitable weaknesses. While currently unpatched CVEs are zero, the historical presence of these vulnerability types warrants caution, as similar issues could emerge in future versions if code quality is not consistently maintained. The static analysis also indicates that 50% of SQL queries are not using prepared statements, which presents a potential risk for SQL injection vulnerabilities, though the taint analysis did not detect any active exploitation pathways for this version.

In conclusion, while version 2.77 has implemented many good security practices and currently appears free of critical vulnerabilities, the plugin's past vulnerability record necessitates vigilance. The use of raw SQL queries and the historical presence of XSS and information exposure vulnerabilities are weaknesses that should be addressed to improve the overall security posture and prevent recurrence.
