Title
monetr: Unauthenticated Stripe webhook reads attacker-sized request bodies before signature validation
Summary
monetr is a budgeting application for recurring expenses. In versions 1.12.3 and below, the public Stripe webhook endpoint buffers the entire request body into memory before validating the Stripe signature. A remote unauthenticated attacker can send oversized POST payloads to cause uncontrolled memory growth, leading to denial of service. The issue affects deployments with Stripe webhooks enabled and is mitigated if an upstream proxy enforces a request body size limit. This issue has been fixed in version 1.12.4.

CVE-2026-39901 (GCVE-0-2026-39901)

Title
monetr: Protected Transactions Deletable via PUT
Summary
monetr is a budgeting application focused on planning for recurring expenses. Prior to 1.12.3, a transaction integrity flaw allows an authenticated tenant user to soft-delete synced non-manual transactions through the transaction update endpoint, despite the application explicitly blocking deletion of those transactions via the normal DELETE path. This bypass undermines the intended protection for imported transaction records and allows protected transactions to be hidden from normal views. This vulnerability is fixed in 1.12.3.
Severity ?
5.7 (Medium)
