No EPSS score is available, and the vulnerability does not appear in the CISA KEV catalog. Because the attack vector requires only unauthenticated access to the REST API, an attacker can exploit the flaw remotely without any prior user interaction. Successful exploitation results in remote code execution, granting the attacker full integrity and confidentiality compromise of the affected site and potentially the entire web server."}}}}, "created": "2026-04-09T08:15:39.085292+00:00", "updated": "2026-04-09T08:25:05.666222+00:00", "vendors": ["davidfcarr", "davidfcarr$PRODUCT$quick_playground", "wordpress", "wordpress$PRODUCT$wordpress"]}
