🎯 Content Summary

Overview

CVE-2026-72898 is a critical, remotely exploitable, unauthenticated SQL injection in the password-reset functionality of self-hosted Metabase. The vulnerable functionality is exposed through the public POST /api/session/reset_password endpoint. A remote attacker who can reach this endpoint can inject an attacker-controlled SQL expression into the Metabase application database, manipulate authentication-related data, and ultimately obtain administ...

🔧 Technical Details

Abusing structured query-builder input: APIs that pass JSON objects into a structured SQL builder must enforce strict schemas and primitive types. If a field expected to contain an identifier can instead contain a builder-specific raw-expression object, an attacker may cross the boundary between data and query syntax. With HoneySQL, a structure equivalent to {:raw "SQL"} causes text to be compiled directly into the statement. Supplying such an object through an insufficiently validated JSON field can therefore create SQL injection even when the application normally uses a query builder rather than string concatenation.

Converting application-database SQL injection into account takeover: SQL injection against an application's internal database can be exploited by targeting authentication workflows and records rather than external business data. Password-reset lookups, user identifiers, password hashes, roles, superuser flags, and s...

🤖 Agent Actions

Updated src/pentesting-web/sql-injection/README.md.

Added:

• Structured query-builder/raw-expression injection technique.
• HoneySQL :raw versus bound/:lift values.
• Metabase password-reset request shape and account-takeover path.
• Application-database pivoting and technical detection indicators.
• Strict schema and AST-construction hardening guidance.
• Four numbered primary/reporting references with inline citations.

Validation passed: clean diff, balanced code fences, valid references, reachable source URLs, and no forbidden sources. mdbook was unavailable locally.
