What is CVE-2026-39901?

The Monetr budgeting application had a vulnerability that allowed authenticated tenant users to bypass the application's restrictions on deleting synced non-manual transactions. Specifically, prior to version 1.12.3, these users could soft-delete such transactions through the transaction update endpoint, even though the application was designed to block deletion via the standard DELETE mechanism. This flaw potentially undermines the integrity of imported transaction records, enabling protected transactions to become hidden from standard views. This issue has been resolved in the latest version.
