Is Johnny Cache Safe to Use in 2026?
Generally Safe
Score 85/100Johnny Cache has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The johnny-cache plugin v0.3 exhibits a generally strong security posture based on the static analysis. It has a limited attack surface with all entry points being AJAX handlers, and importantly, all of these appear to have nonce checks. The absence of direct SQL queries, reliance on prepared statements, and zero file operations or external HTTP requests are all positive indicators. The plugin also shows a commitment to security by including nonce checks on all identified entry points.
However, there are a couple of areas that warrant attention. The output escaping is only 43% properly escaped, indicating a potential for cross-site scripting (XSS) vulnerabilities if user-supplied data is not handled carefully. Furthermore, the taint analysis revealed three flows with unsanitized paths, and while none were classified as critical or high severity, the presence of unsanitized paths is a concern that could lead to unexpected behavior or potential exploits if not mitigated. The plugin's vulnerability history is clean, with no recorded CVEs, which is a very positive sign about its past security.
Key Concerns
- Unsanitized paths in taint analysis
- Low percentage of properly escaped output
