Steps
Written by AI from the record- Check if you run Frappe ERPNext, and whether you have any public-facing portal forms enabled for customers or visitors.
- If you're on ERPNext 15.x, upgrade to 15.112.0 or later.
- If you're on ERPNext 16.x, upgrade to 16.23.0 or later.
- Until upgraded, consider disabling or restricting public portal forms that accept unauthenticated submissions.
- After upgrading, review recently submitted portal form records for suspicious script-like content.
What it is
From the CVE record
Frappe ERPNext before 15.112.0 and 16.x before 16.23.0 contains a stored cross-site scripting vulnerability in a public portal form that accepts unauthenticated submissions and stores content later rendered with insufficient neutralisation. Unauthenticated attackers can submit crafted markup that executes in the browser sessions of staff who review the stored record.
In plain language
Written by AI from the recordA flaw in ERPNext's public web forms before version 15.112.0 lets outsiders plant hidden code that runs when your staff view the submitted record, but this isn't being exploited anywhere and isn't an emergency.
Unauthenticated stored XSS in Frappe ERPNext's public portal form submission handler (CWE-79) allows attacker-supplied markup to persist and execute in staff browser sessions when the record is viewed, enabling session-level compromise within the portal context.
If you're affected
- Employee session hijacking
- Internal data exposure via staff browser
- Trust/credibility damage if abused
