Caylet Security Research is a security research initiative operated by CAYLET LLC.
We participate in authorized vulnerability disclosure and bug bounty programs and conduct research only within the scope and rules established by each program owner.
Rigorous evaluation of modern application logic and authentication mechanics.
Our security research concentrates on web applications, modern APIs, and identity architectures where application logic and access control determine system integrity.
Analysis of modern frontend and server architectures, client-side state handling, input sanitization, and session lifecycles.
REST, GraphQL, and RPC endpoints evaluating data exposure, parameter validation, rate limiting, and interface authorization.
Role-based and attribute-based permissions, privilege separation, token lifecycles, and cross-tenant boundary verification.
Single Sign-On (SSO), OAuth 2.0 / OIDC integrations, Multi-Factor Authentication (MFA), password reset chains, and session tokens.
Broken Object Level Authorization (BOLA/IDOR), vertical and horizontal permission escalation across user roles.
Flaws in state machine transitions, order fulfillment workflows, currency/credit calculations, and transactional edge cases.
Workspace invitations, organization provisioning, audit log fidelity, and collaborative permission structures.
Five non-negotiable standards guiding every assessment.
Safe harbor compliance and responsible disclosure are central to all research operations conducted by CAYLET LLC.
"We test systems only where explicit authorization has been granted."
Every research activity is initiated solely under predefined coordinated disclosure guidelines or formal bug bounty program policies with clear safe harbor protection. We never engage in unsolicited, unauthorized, or destructive testing on third-party infrastructure.
"Program scope and rules define the boundaries of every research activity."
In-scope assets, allowed methods, exclusions, and out-of-scope boundaries established by program owners are strictly respected. We do not target third-party vendors, shared infrastructure, or non-participating subdomains.
"We avoid accessing, retaining or exposing unnecessary third-party data."
If an authorization or exposure issue is encountered, we access only the minimum data necessary to establish proof-of-concept. Personally identifiable information (PII), proprietary business records, and customer credentials are never exfiltrated, saved, or shared.
"Potential vulnerabilities are reported through the appropriate disclosure channel."
All discovered security findings are documented clearly with reproducible steps and submitted exclusively through the program owner's official reporting portal or security contact. We maintain strict confidentiality throughout remediation.
"Testing stops once sufficient evidence exists to demonstrate a potential security issue."
We do not execute automated denial of service, write persistent payloads to shared data stores, alter customer records, or perform lateral pivoting beyond the initial boundary demonstration.
CAYLET LLC engages in vulnerability research exclusively within the clear mandates of program owners. We do not participate in out-of-scope testing, social engineering of employees, physical security evaluations, or denial-of-service testing against production infrastructure.
Our objective is the proactive identification and coordinated remediation of functional and authorization vulnerabilities, ensuring organizations can strengthen their defense posture before potential threats materialize.
