Attackers can submit a serialized XLSXWriter object as the field value to invoke its __destruct() method, deleting arbitrary attacker-specified files such as config.php or backup data, resulting in denial of service and potential application reinstall hijack.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","cwes":["CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://github.com/NeoRazorX/facturascripts/releases/tag/v2026.7","tags":[]},{"url":"https://github.com/NeoRazorX/facturascripts/security/advisories/GHSA-p89j-gj6f-fh6g","tags":[]},{"url":"https://www.vulncheck.com/advisories/facturascripts-php-object-injection-via-widgetselect","tags":[]},{"url":"https://github.com/NeoRazorX/facturascripts/security/advisories/GHSA-p89j-gj6f-fh6g","tags":[]}],"exploitRefs":[{"url":"https://github.com/NeoRazorX/facturascripts/releases/tag/v2026.7","tags":[]},{"url":"https://github.com/NeoRazorX/facturascripts/security/advisories/GHSA-p89j-gj6f-fh6g","tags":[]},{"url":"https://github.com/NeoRazorX/facturascripts/security/advisories/GHSA-p89j-gj6f-fh6g","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw is a PHP object injection vulnerability in FacturaScripts before version 2026.7, allowing attackers to execute arbitrary code and delete critical files, leading to denial of service and potential application reinstall hijack.","exploitability":"Exploitation requires an authenticated attacker and submission of a serialized XLSXWriter object, making it moderately difficult to exploit.","blast_radius":"If exploited, attackers can delete sensitive files like config.php or backup data, causing a denial of service and potential application reinstall hijack, impacting the entire system.","remediation":"Upgrade to FacturaScripts 2026.7 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["php-object-injection","denial-of-service","file-deletion"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-06T08:45:34.916Z"}}
