Report: CVE-2026-41428 - Budibase: Authentication Bypass via Unanchored Regex in Public Endpoint Matcher ...
CVE ID :CVE-2026-41428 Published : April 24, 2026, 7:17 p.m. | 38 minutes ago Description :Budibase is an open-source low-code platform. Prior to 3.35.4, the authenticated middleware uses unanchored regular expressions to match public (no-auth) endpoint patterns against ctx.request.url. Since ctx.request.url in Koa includes the query string, an attacker can access any protected endpoint by appending a public endpoint path as a query parameter. For example, POST /api/global/users/search?x=/api/system/status bypasses all authentication because the regex /api/system/status/ matches in the query string portion of the URL. This vulnerability is fixed in 3.35.4. Severity: 0.0 | NA Visit the link for more details, such as CVSS details, affected products, timeline, and more...
