Is iframe Safe to Use in 2026?
Generally Safe
Score 97/100iframe has a strong security track record. Known vulnerabilities have been patched promptly. It's a solid choice for most WordPress installations.
The "iframe" v6.0 plugin exhibits a generally good security posture in its current static analysis. The code demonstrates a strong commitment to secure coding practices, with all SQL queries utilizing prepared statements and all outputs being properly escaped. There are no identified dangerous functions, file operations, or external HTTP requests, and the plugin does not bundle any external libraries, which helps mitigate risks associated with outdated dependencies. The limited attack surface, consisting of a single shortcode with capability checks, further contributes to its perceived security.
Key Concerns
- History of medium severity XSS vulnerabilities
- No nonce checks on shortcode
