CVE-2026-109653: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in frappe erpnext
Description
CVE-2026-109653 is a stored cross-site scripting (XSS) vulnerability in Frappe ERPNext affecting versions before 15.119.0 and 16.x before 16.31.0. The issue arises because record fields are rendered into HTML attribute contexts without proper escaping. This allows a low-privilege user to inject malicious scripts that execute in the browsers of privileged users viewing the affected pages, potentially leading to account takeover.

Technical Analysis
Frappe ERPNext versions prior to 15.119.0 and 16.31.0 contain a stored cross-site scripting vulnerability due to improper neutralization of input during web page generation. Specifically, record fields are embedded into HTML attribute contexts without escaping, enabling a low-privilege user to store malicious payloads. When privileged users access these records, the payload executes in their browsers, which can lead to account compromise.
Potential Impact
The vulnerability enables attackers with low privileges to inject malicious scripts that execute in the browsers of privileged users. This can result in account takeover of those privileged users, compromising the confidentiality and integrity of the affected ERPNext instance.
Mitigation Recommendations
A fix is available in versions 15.119.0 and 16.31.0. Users should upgrade to these or later versions to remediate this vulnerability. No additional mitigation steps are indicated in the provided data.
