CVE-2026-100682

Budibase Server before 3.45.0 contains an arbitrary file write vulnerability in the PWA icon upload endpoint that extracts user-supplied ZIP archives without proper symlink validation. Attackers with BUILDER role can craft a malicious ZIP with leaf symlink entries followed by duplicate file entries to write arbitrary files as root, enabling remote code execution.
