Custom Columns Security & Risk Analysis

The "custom-columns" plugin v1.0 exhibits a generally positive security posture with no known vulnerabilities or critical code signals. The absence of dangerous functions, raw SQL queries, file operations, and external HTTP requests are all strong indicators of good security practices. Furthermore, the plugin utilizes prepared statements for its SQL queries, which is a critical security measure. The presence of a nonce check is also commendable. However, a significant concern lies in the low percentage of properly escaped output. With only 11% of outputs being escaped, there is a substantial risk of Cross-Site Scripting (XSS) vulnerabilities, especially considering the plugin has 28 output instances. The lack of capability checks is also a potential weakness, though mitigated by the minimal attack surface.
