When such files are executed, an attacker can achieve remote code execution. The weakness is a file\u2011upload flaw (CWE\u2011434). This grants full compromise of affected sites if the uploaded content can be executed by the server.", "risk_and_exploitability": "The CVSS score of 8.8 signals a high\u2011severity flaw. The EPSS value of less than 1% indicates that real\u2011world exploitation is currently rare, likely because the attack requires a user to unknowingly click a malicious link prompting an admin to perform an action. The flaw is not listed in the CISA Known Exploited Vulnerabilities catalog, further suggesting low active exploitation. However, if an attacker can trick an administrator, the impact is severe due to remote code execution."}}}}, "created": "2025-12-10T17:48:47.866113+00:00", "updated": "2026-04-21T17:45:16.480102+00:00", "vendors": ["wordpress", "wordpress$PRODUCT$wordpress"]}
