SCA: security update for github.com/coder/coder/v2 (GHSA-7cc2-r658-7xpf)

high Tenable Self-Hosted Container Security Plugin ID 411990

Description

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

 - Coder allows oragnizations to provision remote development environments via Terraform. Prior to versions
 2.6.1, 2.7.3, and 2.8.4, a vulnerability in Coder's OIDC authentication could allow an attacker to bypass
 the `CODER_OIDC_EMAIL_DOMAIN` verification and create an account with an email not in the allowlist.
 Deployments are only affected if the OIDC provider allows users to create accounts on the provider. During
 OIDC registration, the user's email was improperly validated against the allowed
 `CODER_OIDC_EMAIL_DOMAIN`s. This could allow a user with a domain that only partially matched an allowed
 domain to successfully login or register. An attacker could register a domain name that exploited this
 vulnerability and register on a Coder instance with a public OIDC provider. Coder instances with OIDC
 enabled and protected by the `CODER_OIDC_EMAIL_DOMAIN` configuration are affected. Coder instances using a
 private OIDC provider are not affected, as arbitrary users cannot register through a private OIDC provider
 without first having an account on the provider. Public OIDC providers are impacted. GitHub authentication
 and external authentication are not impacted. This vulnerability is remedied in versions 2.8.4, 2.7.3, and
 2.6.1 All versions prior to these patches are affected by the vulnerability.*It is recommended that
 customers upgrade their deployments as soon as possible if they are utilizing OIDC authentication with the
 `CODER_OIDC_EMAIL_DOMAIN` setting. (CVE-2024-27918)
