Private disclosures and researcher-led findings across additional fintech, cloud, AI, and SaaS platforms.
Real Engagements · Findings Redacted Under NDA
Vulnerability Intelligence
Extracted from live manual engagements across fintech, SaaS, and AI-native products. Targets identified proactively. No automated scanners. No client disclosure without written consent.
Broken Object Level Authorization
Financial Record Mutation via
Predictable Resource Identifier
Fintech SaaS · Pre-Series A · REST API
The /api/v1/accounts/{id}/transactions endpoint performed no server-side ownership validation. Any authenticated session token could be substituted with an incremented integer id to read, overwrite, or hard-delete the complete transaction history of any account on the platform. Exploitation required no elevated privileges, no special tooling -- a browser DevTools request modification was sufficient for full account takeover.
JWT Algorithm Confusion
alg:none Accepted by
Verification Middleware
AI Developer Tooling · Seed Stage · Node.js / Express
The token verification middleware did not enforce a fixed algorithm allowlist. Passing "alg": "none" in a crafted JWT header caused the signature verification step to be skipped entirely. An unauthenticated attacker could forge a token with arbitrary sub and role claims -- including "role": "admin" -- and receive a valid authenticated session with full platform access. The vulnerability existed in the raw jsonwebtoken implementation without the algorithms restriction parameter.
Union-Based SQL Injection
Raw String Concatenation
in Search Handler
E-Commerce Platform · Bootstrapped · PostgreSQL / PHP
The ?q= search parameter was interpolated directly into a raw SQL query string with no parameterisation, escaping, or WAF mitigation. A UNION-SELECT payload against the information_schema.tables endpoint enumerated the full database schema in a single request. Subsequent payloads extracted the complete users, orders, and payment_methods tables. Blind time-based injection confirmed write access was also possible.
Server-Side Request Forgery
IMDS Credential Exfiltration via
Unvalidated Webhook Endpoint
SaaS Integration Platform · Series A · AWS EC2
The webhook registration endpoint accepted arbitrary URLs and performed a server-side HTTP fetch with no IP range validation, scheme restriction, or redirect-follow controls. Supplying http://169.254.169.254/latest/meta-data/iam/security-credentials/ as the webhook destination returned live AWS IAM credentials -- AccessKeyId, SecretAccessKey, and Token -- in the webhook delivery log visible to the registering user. The attached IAM role carried ec2:* and s3:* permissions.
Technical Workflow
Protocol Execution Steps [01-04]
Reconnaissance & Surface Mapping
Manual OSINT and infrastructure analysis to map out the entire attack surface. We identify shadow IT, exposed buckets, and forgotten endpoints.
Deep-Dive Logic Testing
Human researchers test business logic, authentication flows, and race conditions that scanners miss. We look for "impossible" states in your application.
Exploitation & Impact Validation
We don't just find bugs; we verify the actual impact with safe, controlled exploitation. Prove the criticality with zero risk to production stability.
Remediation & Direct Support
Receive a detailed report and direct access to the researcher for patching guidance. We stay on-call until the fix is deployed and verified.
