Show post by category Security & Risk Analysis

The 'show-post-by-category' plugin version 1.0 exhibits a mixed security posture. On the positive side, the static analysis reveals no apparent attack surface through AJAX, REST API, shortcodes, or cron events, and no dangerous functions or file operations were detected. The absence of known CVEs and vulnerability history also suggests a relatively clean track record. However, significant concerns arise from the code analysis. The plugin uses raw SQL queries without prepared statements, which is a major security risk that could lead to SQL injection vulnerabilities. Furthermore, a substantial portion of output is not properly escaped, potentially exposing the site to Cross-Site Scripting (XSS) attacks. The lack of any capability checks or nonce checks, even with no direct entry points identified, means that if any entry points were ever introduced or inadvertently exposed, they would be completely unprotected.
