Attackers can store malicious formulas in entry-data post meta that are later exported unneutralized via fputcsv() or esc_html() in the CSV export functions, causing the formula to execute when an administrator opens the exported file, enabling data exfiltration to an attacker-controlled URL or command execution on the administrator's workstation.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":5.3,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:L","version":"4.0"},{"score":7.1,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","version":"3.1"}],"modifiedAt":1794490512175,"publishedAt":1794490512175,"references":[{"source":"CNA: VulnCheck","tags":["release-notes","patch"],"url":"https://wordpress.org/plugins/gutenverse-form/#developers"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/gutenverse-form-wordpress-plugin-csv-formula-injection-via-form-submission"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
