CVE-2026-54790 InvoicePlane CVE debrief

CVE-2026-54790 is a SQL injection vulnerability in InvoicePlane, a self-hosted open-source application for managing invoices, clients, and payments. The vulnerability exists in versions prior to 1.7.2 and allows an attacker to execute a second-order SQL injection attack by manipulating the custom_field_table value. This can lead to arbitrary schema data queries and application errors or denial of service.

Who should care

Defenders managing InvoicePlane installations, particularly those with exposed or internet-facing deployments, should assess their exposure and prioritize patching to version 1.7.2 or later.

Why it matters

CVE-2026-54790 is a SQL injection vulnerability in InvoicePlane that can lead to arbitrary schema data queries and application errors or denial of service. Defenders managing InvoicePlane installations should assess their exposure and prioritize patching to version 1.7.2 or later.

  • Potential for arbitrary schema data queries
  • Application errors or denial of service
  • Need for verification of custom field configurations
  • Priority for patching to version 1.7.2 or later

Technical summary

The vulnerability exists in InvoicePlane versions prior to 1.7.2, where an administrator-controlled custom_field_table value is stored without validation. This value is later concatenated into the FROM table and WHERE column identifier positions in the mdl_custom_fields::used() function, allowing for a second-order SQL injection attack. Defenders managing InvoicePlane installations should assess their exposure and prioritize patching to version 1.7.2 or later, verifying custom field configurations, and monitoring for suspicious database queries to mitigate potential arbitrary schema data queries and application errors or denial of service.

Defensive priority

Defenders should prioritize patching to version 1.7.2 or later, verifying custom field configurations, and monitoring for suspicious database queries.

Recommended defensive actions

  • Patch InvoicePlane to version 1.7.2 or later
  • Verify custom field configurations to prevent SQL injection
  • Monitor database queries for suspicious activity
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
