Impact
The vulnerability is a classic deserialization flaw that permits untrusted data to instantiate PHP objects during unserialize. This flaw can allow an attacker to construct a crafted payload that may result in arbitrary code execution, data tampering, or privilege escalation within the WordPress installation. The related weakness is listed as CWE-502, indicating improper data handling during deserialization.
Affected Systems
The flaw is present in the NooTheme WeMusic WordPress theme for all releases up through version 1.9.1. Users running the theme in any form that processes user-supplied serialized data are impacted.
Risk and Exploitability
The CVSS score of 8.8 reflects a high impact and that the flaw is exploitable via web requests that carry malicious payloads. With an EPSS score of less than 1%, widespread exploitation is currently unlikely, and the issue is not in the CISA KEV catalog. Nonetheless, the attack can be carried out remotely by delivering a crafted serialized object through exposed input points such as theme settings or content fields, making it a significant risk if not mitigated.
