CVE-2026-7591
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA security flaw has been discovered in TimBroddin astro-mcp-server up to 1.1.1. The impacted element is an unknown function of the file src/index.ts of the component MCP Tool Query Construction. Performing a manipulation of the argument request.params.arguments results in sql injection. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSQL injection vulnerability in astro-mcp-server up to v1.1.1 allows remote attackers to inject malicious SQL via the request.params.arguments parameter in the MCP Tool Query Construction component (src/index.ts). The application constructs database queries using unsanitized user input directly in SQL statements.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify astro-mcp-server installation and versionCheck package.json, node_modules, or run 'npm list astro-mcp-server' to see the installed version. Compare against v1.1.1 and below.Affected if astro-mcp-server is installed and the version is v1.1.1 or lower.
-
Locate the query construction codeInspect the file src/index.ts in the astro-mcp-server installation directory. Look for the MCP Tool Query Construction component.Affected if The file src/index.ts exists and contains SQL query logic.
-
Verify use of request.params.arguments in SQLSearch the codebase for usage of 'request.params.arguments' within SQL query strings. Look for patterns where this parameter is concatenated directly into SQL statements.Affected if request.params.arguments is used in direct string concatenation within SQL queries.
-
Check if parameterized queries are usedExamine src/index.ts for the presence of parameterized queries, prepared statements, or input sanitization functions wrapping the SQL queries that use request.params.arguments.Affected if SQL queries using request.params.arguments do NOT use parameterized queries or prepared statements.
A user is affected if astro-mcp-server v1.1.1 or lower is installed AND the application processes requests through the MCP Tool Query Construction component without parameterized queries.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace direct string concatenation in SQL queries with parameterized queries/prepared statements. Input validation and escaping should not be relied upon as the sole mitigation. Upgrade to a patched version once available.
