# Marten has an injection vulnerability in its full-text search regConfig parameter Advisory record · `GHSA-vmw2-qwm8-x84c` - **Identifiers:** `GHSA-vmw2-qwm8-x84c` · `CVE-2026-45288` - **State:** Confirmed - **Severity:** CVSS 9.8 Critical - **Critical:** Yes: CVSS 9+ - **Weakness (CWE):** [CWE-74](https://cwe.mitre.org/data/definitions/74.html) · [CWE-89](https://cwe.mitre.org/data/definitions/89.html) - **Tags:** [Other injection](https://agentprime.io/advisories/tag/injection.md) · [SQL injection](https://agentprime.io/advisories/tag/sql-injection.md) - **Published:** 14 May 2026 - **Updated:** 9 Jun 2026 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 14 May 2026, 20:46 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Critical Critical, because: - CVSS score 9.8: 9.0 or more. How we decide what’s critical: ## Affected packages - `Marten` (NuGet): affected `<8.37.0`; fixed in `8.37.0` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > Marten versions before 8.37.0 are vulnerable to SQL injection through the regConfig parameter of its full-text search APIs, because the value is inserted into generated SQL without parameterization or validation. An attacker who can supply regConfig input, for example through a request parameter that the application forwards to it, can run arbitrary PostgreSQL statements, with impact depending on the database role used. Upgrade to Marten 8.37.0 or later. Until then, hard-code regConfig to a constant or validate it against an allowlist before passing it to Marten.

Once a person has reviewed it, this page will say what’s vulnerable, what has to be true for your app to be affected, and how to check. ## Severity and exploitation - 9.8 Critical, CVSS 3.1: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`, from CNA (GitHub_M) - **CISA KEV:** Not listed. - **EPSS:** 0.0037, the 31st percentile, on 10 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 31 Oct 2026, 15:22 UTC: First seen by agentprime - 31 Oct 2026, 15:22 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-vmw2-qwm8-x84c) ## Sources - [GitHub Advisory Database: GHSA-vmw2-qwm8-x84c](https://github.com/advisories/GHSA-vmw2-qwm8-x84c) - [OSV: GHSA-vmw2-qwm8-x84c](https://osv.dev/vulnerability/GHSA-vmw2-qwm8-x84c) - - - - - Facts on this page come from the GitHub Advisory Database (CC-BY 4.0), OSV and the other sources listed, as published. We don’t reproduce full advisory descriptions, which can contain exploit code. ## Check whether this affects you A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet. - With the agentprime MCP server (), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: - In a browser: reads your lockfile in the browser, never uploading it. - Whether it touches your code, with file and line: the Claude Code plugin, - As JSON: , or `POST https://api.agentprime.io/v1/match` with your packages () --- The web page: .
