Professional Social Sharing Buttons, Icons & Related Posts – Shareaholic Security & Risk Analysis

The Shareaholic plugin v9.7.13 exhibits a mixed security posture. While it demonstrates good practices such as having no dangerous functions, file operations, or bundled libraries, significant concerns arise from its extensive attack surface and insufficient authorization checks. The analysis reveals a substantial number of AJAX handlers (14 out of 14) that lack proper authentication, creating a wide entry point for potential attacks. Furthermore, only 32% of output escaping is properly handled, indicating a risk of Cross-Site Scripting (XSS) vulnerabilities if untrusted data is not sufficiently sanitized before rendering. The plugin's vulnerability history, with 4 known medium-severity CVEs predominantly involving missing or incorrect authorization and XSS, reinforces these concerns. The recency of the last vulnerability (January 2024) suggests ongoing security challenges.

Despite these weaknesses, the plugin's use of prepared statements for a majority of its SQL queries and the presence of nonce and capability checks in some areas are positive signs. However, the critical issue of unprotected AJAX endpoints, coupled with the history of authorization and XSS flaws, presents a notable risk. The taint analysis shows one flow with unsanitized paths, which, while not classified as critical or high, is still a direct indicator of potential vulnerabilities. In conclusion, while Shareaholic v9.7.13 has some strengths, the large number of unprotected AJAX handlers and the historical pattern of authorization and XSS vulnerabilities necessitate caution.
