Hey Hunter's,
DarkShadow here back again, just look at this one crazy boolean SQLi.
Sometimes .json files load SQLi. So, it's not necessary that only php file parameters we hunt.

Tip: never forget to test boolean SQLi even it is a .json file parameter

Hey Hunter's,
DarkShadow is here back again!
🔥SQL injection in json endpoint💀
Always be check json, js endpoints for SQLi. Make sure you check blind base injections. Cause here only possible blind base injections.

🚨 Bug Bounty / Red Team Tip
CVE-2026-21643 — Critical Pre-Auth SQL Injection (CVSS 9.1) in FortiClient EMS 7.4.4 (multi-tenant mode only)
Unauthenticated attackers can inject arbitrary SQL via the Site HTTP header to the public endpoint
- Affected: Only FortiClient EMS 7.4.4 (multi-tenant/Sites feature enabled)
- Not affected: 7.2.x, 8.0.x, single-site deployments
- Fixed: Upgrade to 7.4.5 or later
- Status: Actively exploited in the wild + public PoCs available
Main Detail Article (Highly Recommended):
Bishop Fox deep-dive with exploitation paths, payloads (e.g.,

Quick Check:
If your EMS login page is internet-facing and running 7.4.4 with multi-tenant enabled → patch ASAP or block public access. Thousands of instances are exposed (Shadowserver ~2k+, Shodan ~1k+).
High-value target for hunters. Patch or restrict immediately!

CVE-2026-21643 — Critical Pre-Auth SQL Injection (CVSS 9.1) in FortiClient EMS 7.4.4 (multi-tenant mode only)
Unauthenticated attackers can inject arbitrary SQL via the Site HTTP header to the public endpoint
/api/v1/init_consts (or login endpoint). This happens before authentication and hits the PostgreSQL backend with superuser-level access in many setups → full DB dump, schema extraction, or RCE (via PostgreSQL features like COPY FROM PROGRAM).- Affected: Only FortiClient EMS 7.4.4 (multi-tenant/Sites feature enabled)
- Not affected: 7.2.x, 8.0.x, single-site deployments
- Fixed: Upgrade to 7.4.5 or later
