Is this vulnerability remotely exploitable?

It can be, if an external user or integration can define or influence cron webhook URLs. In that case, an attacker may leverage the cron subsystem to trigger SSRF from outside the network.

What level of access is required to exploit this issue?

An attacker must be able to create, modify, or otherwise control the cron webhook target configuration. This may require authenticated access to OpenClaw or compromise of an integration that manages cron schedules.

What is the safest general fix pattern for this class of vulnerability?

Route all outbound HTTP requests, including from cron and background jobs, through a centralized, SSRF-aware HTTP client or proxy that enforces strict domain/IP allowlists and blocks access to internal and metadata endpoints.
