SCA: security update for @bytebase/dbhub (GHSA-mwwr-p57h-56pf)

high Tenable Self-Hosted Container Security Plugin ID 448340

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- DBHub is a database MCP server for Postgres, MySQL, SQL Server, Oracle, MariaDB, SQLite. Prior to version
0.22.6, setting `readonly = true` on the `execute_sql` tool does not make the connection read-only. The
connectors are written to set PostgreSQL `default_transaction_read_only=on` (and open SQLite in `readOnly`
mode), but that code is gated on a config value that is never populated, so it never runs. The only thing
left enforcing read-only is a classifier that inspects the first keyword of each statement. Any `SELECT`
that writes or has side effects through a function call passes it. With an ordinary role this allows
sequence tampering; with a privileged role it allows writing arbitrary files on the server (`lo_export`),
reading arbitrary host files (`pg_read_file`), and remote code execution (`dblink` + `COPY ... TO
PROGRAM`). The HTTP transport is unauthenticated and binds to `0.0.0.0` by default, so this is reachable
by any network caller of `/mcp`. Version 0.22.6 patches the issue. (CVE-2026-61788)

Solution

Update the @bytebase/dbhub library and its related packages to version 0.22.6 or later.
