- CWE-862 — Missing Authorization
This CVE was published Sep 12, 2026 and is one of 9 known issues for this plugin.
Update, patch or deactivate.
Update Sprout Invoices to 20.8.16 or later. The authoritative affected range ends before 20.8.16. The application-level fix must require the appropriate invoice capability and verify ownership or assigned access to the exact record before accepting the note update.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
