LH HSTS Security & Risk Analysis
wordpress.org/plugins/lh-hstsHSTS is HTTP Strict Transport Security, a means to enforce using SSL even if the user accesses the site through HTTP and not HTTPS.
Is LH HSTS Safe to Use in 2026?
Generally Safe
Score 85/100LH HSTS has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The lh-hsts plugin v1.25 exhibits a very strong security posture based on the provided static analysis and vulnerability history. The absence of any detected dangerous functions, raw SQL queries, unescaped outputs, file operations, external HTTP requests, or nonce/capability checks is highly commendable. The plugin appears to have a minimal attack surface, with no identified AJAX handlers, REST API routes, shortcodes, or cron events. This indicates a well-written and secure plugin architecture that adheres to best practices for WordPress development.
While the overall security is excellent, the taint analysis reveals two flows with unsanitized paths. Although no critical or high severity issues were found in these flows, the presence of unsanitized paths, even if not leading to immediate exploitable vulnerabilities in this specific version, warrants attention. It suggests a potential area for improvement to ensure absolute data sanitization, even in the absence of clear exploit vectors in the current analysis.
The plugin's vulnerability history is completely clean, with no known CVEs, which further reinforces its secure reputation. This lack of past vulnerabilities suggests consistent development quality and responsible maintenance. In conclusion, lh-hsts v1.25 is an exceptionally secure plugin, with the only minor concern being the two identified unsanitized paths in the taint analysis, which do not currently present a significant risk due to the absence of exploitable code signals.
