CVE-2026-71647 Details
Description
An issue in EGO-Planner-v2 All versions up to commit 5c99a95880401e2599638d567abc0e240396cb42 allows an attacker to cause a denial of service via the checkCollisionCallback, execFSMCallback, planFromGlobalTraj in ego_replan_fsm.cpp
A denial-of-service vulnerability has been identified in EGO-Planner-v2, all versions prior to commit 5c99a95880401e2599638d567abc0e240396cb42. The issue arises in the replanning state machine, where the checkCollisionCallback, execFSMCallback, and planFromGlobalTraj functions in ego_replan_fsm.cpp can be exploited to create a persistent recovery loop. This occurs when a UAV repeatedly detects safety conflicts and attempts to replan, but fails to resolve the issues, leading to a cycle of emergency stops and failed recovery attempts.
No specific remediation is currently available, but addressing the inconsistent recovery semantics and clearance handling in the trajectory optimization process could mitigate the issue.
