Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Invoice Ninja versions before 5.13.4 are vulnerable to stored cross-site scripting through invoice line item descriptions, which bypass the existing denylist filter. An authenticated user who can create or edit invoices can plant a script that runs in the browser of anyone who views the invoice, including clients using the portal, potentially enabling session hijacking. Upgrade to version 5.13.4, which sanitizes line item descriptions.
