This leads to unauthorized access to, edit, or delete resources such as boards, tasks, or other object types governed by the plugin. The weakness is classified as CWE-639.", "risk_and_exploitability": "Given that the CVSS score is 8.1, this vulnerability is considered high severity. The EPSS score is <1% and the vulnerability is not listed in CISA KEV, indicating low probability of exploitation at this time. Based on the description, it is inferred that an attacker can construct requests with guessed or enumerated object identifiers to read or manipulate protected data. It is inferred that the likely attack vector is remote via the web, assuming the attacker can access the WordPress site. No evidence of active exploitation is reported, but the flaw enables privilege escalation within the WordPress installation."}}}}, "created": "2026-04-15T13:38:28.755767+00:00", "updated": "2026-04-16T02:45:06.076896+00:00", "vendors": ["mahmudul_hasan_arif", "mahmudul_hasan_arif$PRODUCT$fluentboards", "wordpress", "wordpress$PRODUCT$wordpress"]}
