Evolver AI agent engine: path traversal, command injection and prototype pollution flaws

Three vulnerabilities (CVE-2026-42075, CVE-2026-42076, CVE-2026-42077) were disclosed in EvoMap's Evolver self-evolving engine for AI agents, allowing arbitrary file writes via the skill download --out flag, remote code execution via unsanitised input to an execSync curl command, and prototype pollution in the mailbox store module. All were patched in version 1.69.3.
