Summary
Keep 0.34.10 through 0.55.0 contains a blind SQL injection vulnerability in its CEL-to-SQL converter, which inserts bracket-indexed JSON keys from CEL filters unescaped into JSON path expressions for SQLite, PostgreSQL, and MySQL. Authenticated users with read:alert permission can submit crafted CEL expressions to /alerts/query or the cel parameter of /incidents, using result counts as a boolean oracle to extract other tenants' alerts and password hashes.
