CVE-2026-12958

Missing symlink validation in Language Servers for AWS may allow an arbitrary file write outside of the workspace trust boundary. This may occur when a local user opens a workspace with a maliciously crafted symlink that resolves to a file path outside the workspace trust boundary. To remediate this issue, users should upgrade to version 1.69.0 or higher.
