Not reviewed by a person. > The Microsoft.NETCore.App.Runtime packages for linux, linux-musl, osx and win platforms (arm, arm64, x64 variants as listed) are affected in .NET 7.0 versions before 7.0.19 and .NET 8.0 versions before 8.0.5. A remote code execution flaw exists from a stack buffer overrun in the .NET Double Parse routine, and the advisory gives no details on the attack conditions. Upgrade to 7.0.19 or 8.0.5 or later, then restart applications and recompile and redeploy any self-contained apps.

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 - 6.3 Medium, CVSS 3.1: `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C`, from CNA (microsoft) - **CISA KEV:** Not listed. - **EPSS:** 0.012, the 69th percentile, on 11 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 14 May 2024, 17:22 UTC: [Published by the maintainers as a GitHub repository advisory](https://github.com/dotnet/runtime/security/advisories/GHSA-7fcr-8qw6-92fr) - 31 Oct 2026, 15:22 UTC: First seen by agentprime - 31 Oct 2026, 15:22 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-7fcr-8qw6-92fr) ## Sources - [GitHub Advisory Database: GHSA-7fcr-8qw6-92fr](https://github.com/advisories/GHSA-7fcr-8qw6-92fr) - [OSV: GHSA-7fcr-8qw6-92fr](https://osv.dev/vulnerability/GHSA-7fcr-8qw6-92fr) - - - - - - - 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: .
