Hi,

The following vulnerability was published for ruby-ruby-lsp.

CVE-2026-34060[0]:
| Ruby LSP is an implementation of the language server protocol for
| Ruby. Prior to Shopify.ruby-lsp version 0.10.2 and ruby-lsp version
| 0.26.9, the rubyLsp.branch VS Code workspace setting was
| interpolated without sanitization into a generated Gemfile, allowing
| arbitrary Ruby code execution when a user opens a project containing
| a malicious .vscode/settings.json. This issue has been patched in
| Shopify.ruby-lsp version 0.10.2 and ruby-lsp version 0.26.9.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
