UnverifiedBy moving SSRF validation down to the langchain-core layer, all upper-layer applications that depend on this core library can automatically receive protection without each needing to implement it independently.73% similarUnverifiedSSRF利用中常被检测的危险协议包括file://（读取本地文件）、dict://（探测端口开放状态）、ftp://（有时可绕过过滤）69% similarUnverifiedBlocklisting private addresses and metadata addresses by default is the most fundamental and critical step in defending against SSRF attacks, and developers implementing MCP tools with network access capabilities should refer to this approach as a priority.68% similarUnverifiedCommon practices for defending against SSRF include: resolving the target domain name to an IP and then determining whether it falls within restricted ranges such as private address ranges, link-local addresses, and loopback addresses; restricting protocols to only allow http/https; and re-performing validation after each redirect.68% similarUnverified完善的 SSH 访问防护应结合网络层加密隧道、SSH 密钥认证、MFA 多因素验证和最小权限原则等多层防御66% similar
