Deeper analysis
The Filr WordPress plugin before version 1.2.3.6 contains a remote code execution vulnerability tracked as CVE-2023-5762. The flaw is classified under CWE-94 and carries a CVSS 3.1 score of 8.8, reflecting network-accessible attack vectors that require low complexity and low-privileged credentials. It affects any site running the vulnerable plugin and permits arbitrary operating-system command execution.
An authenticated user with Author-level privileges can exploit the issue to run commands on the underlying server, resulting in full host compromise including the ability to read, modify, or delete data and potentially pivot within the environment. No user interaction or special UI conditions are required.
Public advisories published by WPScan recommend upgrading the Filr plugin to version 1.2.3.6 or later to remediate the vulnerability. The current EPSS score of 0.1424 has shown no material increase since disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
