Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Mithril client library (crates.io mithril-client) versions before 0.12.2 do not validate the ledger state files in Cardano database snapshots, so a tampered ledger state could be distributed through snapshots and not be detected by nodes started from them. The source describes this as a risk from a compromised or malicious aggregator, and it gives few details on exploitation. Upgrade mithril-client to 0.12.2 or later.
