The vulnerability is not listed in CISA\u2019s KEV catalog, so no known public exploits have been reported. An attacker can exploit the flaw remotely by sending HTTP requests to the affected endpoints without any authentication, provided the target uses a vulnerable version. The high severity combined with low exploitation probability points to a moderate overall risk that still demands remediation."}}}}, "created": "2026-02-23T14:32:29.986558+00:00", "updated": "2026-04-18T11:30:44.311310+00:00", "vendors": ["frappe", "frappe$PRODUCT$erpnext"]}
