CVE-2022-24912: Timing Attack

The package github.com/runatlantis/atlantis/server/controllers/events before 0.19.7 are vulnerable to Timing Attack in the webhook event validator code, which does not use a constant-time comparison function to validate the webhook secret. It can allow an attacker to recover this secret as an attacker and then forge webhook events.

Security readout for executives and security teams

Plain-English summary

Atlantis versions before 0.19.7 used a webhook secret check that could leak information through response timing. If an attacker recovered the secret, they could forge webhook events. This matters because Atlantis often automates infrastructure workflows, so forged events could undermine trust in automation triggers.

Executive priority

Treat as high priority for teams running Atlantis-backed infrastructure automation. The direct business risk is loss of trust in webhook-triggered automation if a secret was recovered. Prioritize upgrade, secret rotation, and exposure review.

Technical view

CVE-2022-24912 affects github.com/runatlantis/atlantis/server/controllers/events before 0.19.7. The webhook event validator did not use constant-time comparison for the webhook secret, creating a timing side channel. Sources state this could let an attacker recover the secret and forge webhook events.

Likely exposure

Exposure is most likely in Atlantis deployments or applications using the affected Go package before 0.19.7, especially where webhook endpoints are reachable by untrusted networks and configured with a shared webhook secret.

Exploitation context

The provided sources do not show known active exploitation, and KEV is false. The issue is remotely reachable, unauthenticated, and low complexity per CVSS, but successful abuse depends on practical timing measurement conditions and a vulnerable webhook secret validator.

Researcher notes

The source bundle names the affected package and pre-0.19.7 range, but does not provide broader product matrices or active exploitation evidence. CVSS is 7.5 with network, no privileges, no user interaction, and high confidentiality impact.

Mitigation direction

  • Upgrade Atlantis or the affected package to version 0.19.7 or later.
  • Confirm the fix containing constant-time secret comparison is present.
  • Rotate webhook secrets after upgrading if the endpoint was exposed.
  • Review vendor, Snyk, and project guidance for environment-specific actions.
  • Limit webhook endpoint exposure where operationally feasible.

Validation and detection

  • Inventory Atlantis deployments and dependency versions.
  • Identify any use of github.com/runatlantis/atlantis/server/controllers/events before 0.19.7.
  • Verify webhook validation uses constant-time comparison after remediation.
  • Review webhook logs for unusual or unexpected events during the exposure window.
  • Confirm rotated secrets are configured consistently across webhook providers and Atlantis.
