CVE-2022-3383
Published: 29 November 2022
Summary
CVE-2022-3383 is a high-severity Code Injection (CWE-94) vulnerability in Ultimatemember Ultimate Member. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 2.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The Ultimate Member plugin for WordPress is vulnerable to remote code execution in versions up to and including 2.5.0. The flaw exists in the get_option_value_from_callback function, which accepts attacker-controlled input and passes it directly to call_user_func, enabling arbitrary PHP execution. The issue is tracked as CWE-94 and carries a CVSS 3.1 score of 7.2.
An authenticated attacker with administrative privileges can exploit the vulnerability over the network to execute arbitrary code on the underlying server, resulting in full compromise of confidentiality, integrity, and availability. No user interaction is required, and the attack can be performed remotely once administrative access is obtained.
Public references point to a patched changeset in the WordPress plugin repository and detailed advisories from Wordfence that describe the affected code path and remediation steps. Administrators should update to a version newer than 2.5.0 as soon as possible. The EPSS score has remained stable at 0.3492 with no reported rise after 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.
