This flaw creates a stored XSS vector that executes the payload in the browsers of any visitor who views the affected page, enabling session hijacking, defacement, or the execution of other malicious actions.

The vulnerability is not listed in CISA\u2019s KEV catalog. Exploitation requires authentication at the contributor level or higher, so the risk is constrained by the role permissions in place. Nonetheless, once an attacker has the necessary credentials, the stored XSS can be deployed immediately. Official remediation is to upgrade to 5.5.64 or newer, which restores proper input validation and output escaping; as a temporary measure, removing or disabling the wpda_app shortcode for contributors can mitigate exposure."}}}}, "created": "2026-02-16T12:02:14.517122+00:00", "updated": "2026-04-15T18:30:10.963306+00:00", "vendors": ["peterschulznl", "peterschulznl$PRODUCT$wp_data_access_\u2013_no-code_app_builder_with_tables,_forms,_charts_&_maps", "wordpress", "wordpress$PRODUCT$wordpress"]}
