CVE-2026-4991Network attack vector

Cross-site scripting via unneutralized enquiry notes

Published Mar 27, 2026 · Updated Mar 27, 2026

Cross-site scripting in QDOCS Smart School 7.0 through 7.2 allows remote authenticated users to alter rendered content via Note input. The Admission Enquiry Module's undisclosed /admin/enquiry handler places attacker-controlled Note input into generated web content without adequate neutralization. Low privileges and passive interaction by another user are required; execution is confined to attacker-supplied script in the viewer's browser, with no published confidentiality or availability impact.
