F-010 / DEVA11Y-480 — extractVersion() did not validate the version string parsed from HTTP redirect filenames (CWE-22). A crafted filename with ../ segments could write outside the cache directory. Add character allowlist and reject traversal sequences. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
