CVE-2026-14967: Blacklanternsecurity Bbot

Low severity, CVSS 3.1. EPSS: 0.3% chance of exploitation in the next 30 days.

BBOT's `github_workflows` module could be induced to write a downloaded artifact outside its configured output directory: its path-containment check did not resolve `..`, so a crafted `CODE_REPOSITORY` URL could traverse out of the intended folder. The write is bounded to two directory levels above the output location and its target is determined by the operator's configuration, not the attacker.
