Insufficient sanitization and escaping of data in the prepareCellOutput() method allows an attacker to embed malicious scripts into table cells of the Link, Image, or Email column types. When a user opens a page containing the compromised table, the arbitrary script executes in the user\u2019s browser, potentially enabling cookie theft, session hijacking, defacement, or other client\u2011side attacks. The flaw is classified as CWE-79.", "risk_and_exploitability": "The CVSS score of 4.7 indicates a medium impact, and the EPSS score is currently not available, so the likelihood of exploitation is uncertain. The vulnerability is not listed in the CISA KEV catalog. Attackers can exploit it by tricking an administrator into importing a malicious CSV or Excel file containing script\u2011laden data; this is inferred from the description and is a remote attack vector with the prerequisite of an admin action. Once the data is imported, any user who visits the page will have the script executed in their browser."}}}}, "created": "2026-04-21T00:00:13.344622+00:00", "updated": "2026-04-22T11:47:09.764069+00:00", "vendors": ["wordpress", "wordpress$PRODUCT$wordpress", "wpdatatables", "wpdatatables$PRODUCT$wpdatatables_\u2013_wordpress_data_table,_dynamic_tables_&_table_charts_plugin"]}
