Is Billy Safe to Use in 2026?
Generally Safe
Score 100/100Billy has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The "billy" v2.2.1 plugin exhibits a generally strong security posture based on the provided static analysis and vulnerability history. The lack of any known CVEs and the fact that all identified SQL queries utilize prepared statements are positive indicators of secure development practices. Furthermore, the plugin demonstrates good output escaping hygiene with 91% of outputs being properly escaped. The presence of nonce and capability checks, although limited, suggests an awareness of WordPress security best practices. However, a single flow with an unsanitized path identified in the taint analysis warrants attention, even if it didn't result in a critical or high-severity finding. This indicates a potential for issues related to file operations or path manipulation that, while not exploited in this version, could be a vulnerability point in other contexts.
