This CVE exposes four SQL injection points in Apache InLong versions 2.0.0 through 2.4.0: dbName, tableName, schemaName, and username. The critical detail isn't that SQL injection exists — it's that all four are vulnerable simultaneously. These aren't random variables; they're the metadata parameters of a database connection layer. The fact that all four are injectable suggests the framework provides no native protection, no parameterized query abstractions, and no input validation scaffolding for these parameters. When developers must consciously escape every metadata parameter individually, they will eventually fail to do so under time pressure or when onboarding new contributors. This is an ergonomic failure — the API makes unsafe SQL construction the path of least resistance.

The cherry-pick reference to issue #12135 implies the fix was surgical rather than architectural — likely patching individual injection points rather than redesigning the query construction layer. This means the underlying hazard may persist for future parameters not yet identified. Verify whether the 2.4.0 release introduces parameterized queries throughout, or merely sanitizes the four named inputs.

The blast radius is extraordinary. These parameters control the database connection itself, not individual application queries. Exploiting them doesn't compromise one table — it compromises the data integration layer that governs how InLong moves data between systems. In a platform where the trust radius often extends to upstream sources, downstream sinks, and adjacent pipeline tooling, complete database takeover means lateral movement across the entire data infrastructure.

Prioritize upgrading to 2.4.0 or later. For organizations unable to upgrade immediately, examine the commit diff for #12135 — if it touches only the four named parameters without refactoring the query construction pattern, assume the vulnerability class persists in other metadata parameters. Audit the codebase for similar dynamic SQL construction with connection metadata. The fix addresses four known injection points; the vulnerability pattern may exist elsewhere.
