What problem does it solve?
Web applications often have subtle session management flaws that lead to persistent account takeover (ATO), which are frequently missed in standard security assessments and can result in critical data breaches or unauthorized access. This skill eliminates guesswork from identifying these high-impact vulnerabilities with proven, field-validated testing methodologies.
Core Features & Use Cases
- 8+ High-Impact Session Flaw Classes: Covers session fixation, logout/password-change invalidation gaps, refresh-token reuse without detection, JWT-as-session misconfigurations, predictable session IDs, cookie attribute weaknesses, OAuth/SSO session linkage gaps, and DBSC downgrade vulnerabilities.
- Validated, Low-False-Positive Testing: Enforces a strict two-session validation rule (attacker + victim sessions) with body-diff checks and negative controls to eliminate false positives, ensuring only real, exploitable flaws are reported.
- Use Case: For a bug bounty hunter or penetration tester, use this skill to systematically test a target's authentication flows, catch persistent ATO vectors that survive password resets, and produce evidence-backed reports that meet program quality standards.
Quick Start
Use the hunt-session skill to test a target web application's session handling for fixation, invalidation gaps, and cookie attribute flaws following the provided two-session validation workflow.
