How can this vulnerability be detected on my network or system? Can you suggest some commands?

Detection involves checking for unauthorized file uploads, especially web shells, in the WordPress Store Locator plugin directories. Since the vulnerability allows arbitrary file uploads by administrators, monitoring for unusual or unexpected files (e.g., PHP web shells) is key. Plugin-based malware scanners may be unreliable, so manual inspection or professional incident response is recommended. Specific commands are not provided in the resources. [1]
