CVE-2026-40481

HIGH

7.5

Description

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.
