Obol pushes urgent Charon upgrade after CA key compromise hits ETH staking

Obol is urging node operators to immediately upgrade its Charon client after a compromise of a CA key, with a patch that tightens certificate checks in Go. The disclosure matters because Obol's mainnet clusters hold roughly 422,862 ETH in its latest daily snapshot, so any trust or validation flaw in the middleware touches a large pool of staked ether. Traders should watch for validator exits or slashing events, though the fix appears targeted rather than a protocol-wide failure.
