Bilibili Messager | B站私信助手

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Bilibili private-message helper that uses a logged-in dedicated browser profile; users should be careful to confirm any outgoing message explicitly.

Install only if you are comfortable letting the agent read selected Bilibili private-message content and send DMs from the logged-in account. Use a dedicated openclaw browser profile, verify the account before use, and require an exact confirmation that includes the recipient and message before allowing any send or reply.

Finding

The skill allows broad confirmation phrases such as '好', '确认', '发', and '发吧' to authorize an irreversible outbound DM. In a conversational system, these phrases can easily appear ambiguously in normal dialogue or be elicited by prompt manipulation, creating a real risk of unintended message sending from the logged-in account.
