SCA: security update for github.com/runatlantis/atlantis (GHSA-26w5-6g95-gj28)

high Tenable Self-Hosted Container Security Plugin ID 446235

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Atlantis is a self-hosted golang application that listens for Terraform pull request events via webhooks.
 From 0.19.8 until 0.45.0, Atlantis does not consistently validate user-controlled workspace values
 supplied through accepted repository-level atlantis.yaml configuration or authenticated /api/plan input
 before joining them into local workspace paths. Traversal segments can escape the intended per-pull
 workspace directory and cause clone preparation or other working-directory code paths to call
 os.RemoveAll, os.MkdirAll, or related filesystem operations on out-of-bounds directories before Terraform
 rejects the invalid workspace name. This can create, delete, or reuse writable paths with the privileges
 of the Atlantis process, causing integrity loss or denial of service. This issue is fixed in version
 0.45.0. (CVE-2026-64679)

Solution

Update the github.com/runatlantis/atlantis library and its related packages to version 0.45.0 or later.
