Is Speed Optimizer – The All-In-One Performance-Boosting Plugin Safe to Use in 2026?
Generally Safe
Score 96/100Speed Optimizer – The All-In-One Performance-Boosting Plugin has a strong security track record. Known vulnerabilities have been patched promptly.
The sg-cachepress plugin v7.7.7 exhibits a mixed security posture. On the positive side, it demonstrates strong practices in SQL query preparation (96%) and output escaping (99%), which are crucial for preventing common web vulnerabilities. The absence of bundled libraries and a relatively low number of file operations and external HTTP requests are also good signs. However, significant concerns arise from the extensive attack surface exposed through AJAX handlers, with all 7 handlers lacking authentication checks. Furthermore, the taint analysis reveals 3 flows with unsanitized paths, including 2 of critical severity, indicating potential for privilege escalation or arbitrary code execution if these paths are reachable by an attacker. The vulnerability history shows a past critical vulnerability, underscoring the need for vigilance, especially since the last known vulnerability was recent. While the current version is unpatched, the historical trend of 'Missing Authorization' vulnerabilities, coupled with the current lack of authorization on AJAX handlers, is a major red flag.
Key Concerns
- All AJAX handlers lack authentication checks
- 2 critical severity taint flows with unsanitized paths
- 3 flows with unsanitized paths
- 1 critical CVE in vulnerability history (even if patched)
- Common vulnerability type: Missing Authorization
