| description | [LAB-GATED; discovery is not runtime authorization; offensive/dual-use — authorized-lab gate] Tests APIs for excessive data exposure where endpoints return more data than the client application needs, relying on the frontend to filter sensitive fields. The tester intercepts API responses and analyzes them for leaked PII, internal identifiers, debug information, or sensitive business data that the UI does not display but the API transmits. This maps to OWASP API3:2023 Broken Object Property |

AUTHORIZED-LAB ONLY. Offensive/dual-use capability. Use exclusively against systems you own or have explicit written authorization to test. Owner-authorized metadata discovery does not authorize runtime actions; use requires an explicit authorized-engagement decision.
Source class: labgated
Owner-authorized discovery: true
Runtime/action authorization: false
Risk gate (registry metadata): "offensive/dual-use — authorized-lab gate"
Discovery does not authorize execution. Obtain explicit current-task authorization before any offensive or dual-use action.
Before acting, read the authoritative source file above completely from beginning to end. If the governed source is absent, run node _SYSTEM/Scripts/skill-recall.mjs --show cyber-exploiting-excessive-data-exposure-in-api and read its complete verified output. Follow that source as the skill body; this adapter is a non-authoritative metadata-and-pointer projection.
