CVE-2026-85291InvoicePlane IDOR: Horizontal Privilege Escalation via Password Change Without Authorization Check
Medium 6.5
In plain English
A medium-severity authorization bypass via user-controlled key in InvoicePlane from InvoicePlane. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 26% of all known vulnerabilities).
Official description
InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane's Users::change_password() method accepts a user_id from the URL and updates that account's password without an object-level authorization check. An authenticated secondary administrator can target the primary administrator account and replace its password without knowing the current password. The attacker can then take over the primary account and access its data and privileges. This issue is fixed in version 1.7.2.
