Is WP JavaScript Error Logger Safe to Use in 2026?
Generally Safe
Score 85/100WP JavaScript Error Logger has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The "wp-javascript-error-logger" plugin version 1.0 exhibits a concerning security posture due to significant weaknesses in its attack surface and output handling. While the plugin does not appear to use dangerous functions, execute raw SQL queries, perform file operations, or make external HTTP requests, these positives are overshadowed by critical omissions. The presence of two AJAX handlers, both lacking any form of authentication or capability checks, creates a wide-open entry point for malicious actors. Furthermore, the analysis indicates that 100% of its outputs are not properly escaped, posing a direct risk of Cross-Site Scripting (XSS) vulnerabilities. The absence of any recorded vulnerabilities in its history might suggest a lack of past scrutiny or a limited track record, but it does not negate the immediate risks identified in the static analysis. The plugin's strengths in avoiding common pitfalls like raw SQL and dangerous functions are commendable, but they are severely undermined by the unprotected AJAX endpoints and unescaped output, making it a high-risk plugin in its current state.
Key Concerns
- Unprotected AJAX handlers present
- Output escaping not used
- No nonce checks on AJAX handlers
- No capability checks on AJAX handlers
