CVE-2026-109633: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in frappe erpnext
Description
CVE-2026-109633 is a stored cross-site scripting (XSS) vulnerability in Frappe ERPNext. It affects versions before 15.119.1 and 16.x before 16.32.0.

Technical Analysis
Frappe ERPNext versions prior to 15.119.1 and 16.0.0-beta.1 up to but not including 16.32.0 contain a stored cross-site scripting vulnerability. The vulnerability arises because input submitted via a public-facing booking page is stored without proper neutralization or sanitization. When a privileged user views this content, the malicious script executes in their session context, potentially allowing an attacker to perform actions as that user and compromise their account.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to execute arbitrary scripts in the context of a privileged user's session. This can lead to account takeover of the privileged user, compromising the confidentiality and integrity of the affected system and data.
Mitigation Recommendations
A fix is available in versions 15.119.1 and 16.32.0 and later. Users should upgrade to these versions or later to remediate the vulnerability. Patch status is confirmed by the affected version ranges indicating fixed versions. No additional mitigation steps are specified.
