# Remediation Handoff: CVE-2026-93710

## Summary

NVD: Dancer2 versions from 2.0.0 before 2.2.0 for Perl dispatch a route that a dying hook refused when the exception handler halts the response in compile_hooks. NVD: A hook that dies fires core.app.hook_exception, then calls cleanup unless the failing hook is the exception handler. NVD: A handler that halts does not stop that cleanup, which discards the request, response and session the dispatcher has yet to read, so the refused route runs.

## Safe AI / Codex handoff

* Goal: Prepare a defensive remediation plan for CVE-2026-93710 using only provided public-safe source context and any separate repo context supplied by the user.
* Allowed actions: summarize vendor guidance, prepare a defensive remediation plan, identify affected dependencies only when repo context is separately provided by the user, suggest tests and validation steps, document human verification questions
* Disallowed actions: generate offensive code, provide payloads, scan external targets, change production systems, merge or deploy changes, create GitHub issues or pull requests without explicit separate approval
* Acceptance criteria: Affected product or dependency presence is confirmed by a human., Affected version is confirmed or marked not applicable., Official advisory or source reference is reviewed., Patch, fixed version, mitigation, workaround, or monitor-only decision is documented., Validation steps are proposed without external scanning or production mutation.
* Human approval required: true
