Is BJ Lazy Load Safe to Use in 2026?
Use With Caution
Score 53/100BJ Lazy Load has 1 unpatched vulnerability. Evaluate alternatives or apply available mitigations.
The "bj-lazy-load" plugin v1.0.9 exhibits a mixed security posture. While the static analysis shows a very small attack surface with no identified AJAX handlers, REST API routes, shortcodes, or cron events that are unprotected, this is overshadowed by significant code-level concerns and a concerning vulnerability history. The presence of a dangerous function like "unserialize" without clear context on its usage and sanitization is a red flag. Furthermore, the taint analysis reveals a critical issue: 4 out of 4 analyzed flows have unsanitized paths, all with high severity. This strongly suggests potential vulnerabilities that could allow attackers to manipulate file paths or execute arbitrary code if these flows are exposed to user input. The plugin's vulnerability history is also concerning, with one critical historical CVE categorized as PHP Remote File Inclusion, indicating past exploitable weaknesses. Although this specific CVE is currently patched, it points to a pattern of potentially insecure coding practices that could resurface or manifest in new ways. The lack of capability checks and a low percentage of properly escaped outputs further add to the security concerns. In conclusion, despite a seemingly small attack surface, the plugin has significant underlying code quality issues and a history that warrants caution.

- High severity unsanitized taint flows (4)
