What is CVE-2026-45061?

Budibase, an open-source low-code platform, has a vulnerability related to its Plugin URL upload endpoint that improperly validates submitted URLs. The current method checks for a single substring, '.tar.gz', allowing any URL containing this substring to proceed unchecked. This leaves the platform susceptible to Server-Side Request Forgery (SSRF), especially in scenarios where the default blacklist for private IP ranges can be bypassed or when following HTTP redirects to internal targets. To mitigate this issue, users should upgrade to version 3.35.10, which includes necessary fixes to improve URL validation measures.
