Official description
Saltcorn is an extensible, open source, no-code database application builder. Prior to 1.4.6, 1.5.6, and 1.6.0-beta.5, a SQL injection vulnerability in Saltcorn’s mobile-sync routes allows any authenticated low-privilege user with read access to at least one table to inject arbitrary SQL through sync parameters. This can lead to full database exfiltration, including admin password hashes and configuration secrets, and may also enable database modification or destruction depending on the backend. This vulnerability is fixed in 1.4.6, 1.5.6, and 1.6.0-beta.5.
