GHSA-28XX-PPPM-VQFF ydb-go-sdk's transactions are not committed using the `options.WithCommit()` option on last call `table.Transaction.Execute` in transaction

Impact Transactions were NOT committed despite the explicit options.WithCommit flag using table service client. Because of this, clients did not commit changes to the transaction, relying on the fact that the transaction commit was successful. This led in rare cases to a loss of data consistency...

Overview Affected versions of this package are vulnerable to Interpretation Conflict in the JSON-RPC and MCP protocol message parsing. An attacker can bypass intermediary inspection or cause cross-implementation inconsistencies by sending protocol messages with non-standard field casing or Unicod...

MCP Go SDK Vulnerable to Improper Handling of Case Sensitivity

The Go MCP SDK used Go's standard encoding/json.Unmarshal for JSON-RPC and MCP protocol message parsing. Go's standard library performs case-insensitive matching of JSON keys to struct field tags — a field tagged json:"method" would also match "Method", "METHOD", etc. Additionally, Go's standard...

CVE-2026-27896 MCP Go SDK Vulnerable to Improper Handling of Case Sensitivity
