Juristriction would add context to your note. Liability differs from place to place.
Personally I'm of the opinion that in most juristrictions volunteers would have no liability, but I am not a lawyer, so if in doubt run the question past a local lawyer.
Plus, who exactly is going to come after you for liability? Liability for what?
You’re aware. That bring liability. Unlikely liability. But the only person in litigation or prosecution distance, even if low level, is likely to get bonds. Particularly if someone can show knowledge and inaction, and thus plausible complicity.
