Is Quaderno for EDD Safe to Use in 2026?
Generally Safe
Score 100/100Quaderno for EDD has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The edd-quaderno plugin version 1.38.1 presents a moderate security risk due to several concerning findings in the static analysis. While the plugin has no recorded vulnerability history, indicating a potentially stable past, the code itself shows weaknesses. The presence of one unprotected AJAX handler represents a significant entry point for potential attacks, especially when combined with the use of the `unserialize` function without proper sanitization, which could lead to remote code execution if exploited. Furthermore, a concerning percentage of output is not properly escaped, increasing the risk of cross-site scripting (XSS) vulnerabilities.
Key Concerns
- Unprotected AJAX handler
- Use of unserialize()
- Unescaped output
- Missing nonce checks
- Missing capability checks
