Severity: low · CVSS 3.1 · Published 2023-07-27

Saltcorn is a low-code web application platform that allows administrators to build and customize applications using plugins. A malicious tenant administrator can bypass plugin safety restrictions and install unsafe plugins through a pack import feature, potentially gaining access to data from other tenants within the same Saltcorn installation. This allows compromise of all tenant instances when an untrusted user has admin privileges.

## Technical details

The vulnerability is a privilege escalation and security-control bypass in the plugin installation mechanism. The root cause is that the safety check for "unsafe" plugins (which may access system resources or other tenant data) is performed against a tenant-controlled store configuration rather than the root server's approved plugin list. An attacker with tenant admin privileges can add a custom plugin store URL, import unapproved unsafe plugins via pack import, and install them despite server-level restrictions. The vulnerability requires high privileges (tenant admin role) and no user interaction. An attacker can execute arbitrary plugin code to exfiltrate data from other tenants or disrupt availability. A fix was merged in PR #1973 to check against the root-level configuration instead of the tenant store.
