ByteStash 1.5.10 before 1.6.2 Insufficient Session Expiration via API Keys

5.3 mediumFix available

Medium (5.3) in jordan-dalby bytestash.

ByteStash 1.5.10 before 1.6.2 contains an insufficient session expiration vulnerability that allows holders of API keys to keep access after account deactivation because validateApiKey never checks account status. Attackers holding a deactivated account's API key can read, create, modify and delete its snippets via /api/snippets and use every MCP tool via /mcp.
