Second-Order SQLi Field Companion
FreeSQL Injection Detection
Flags a SQL sink reading a @Entity field that's ALSO confirmed, elsewhere in the project, to be written from unsanitized HTTP input.
The gap it fixes
CWE-89, the second-order form: the tainted value passes through persistent storage (a real database) between the write and the read. Documented explicitly as the real blind spot of simple SAST tools -- "SAST tools excel at direct input-to-query flows but struggle when malicious data is stored and later used in a different execution context... most simple pattern-matching SAST tools fail because they don't model the database as a taint propagation intermediary." Checkmarx and Fortify (real, confirmed enterprise SAST) model this exact pattern -- neither is free, an inline IDE plugin, or Communit
