CVE-2026-41896 – Webhook HMAC Signature Bypass Enabling Unauthenticated Deployment Trigger – Cool…

Be the first to know when new zero-days emerge:

Summary

CVE-2026-41896 is a high-severity improper authentication vulnerability (CWE-287) in Coolify, an open-source self-hostable platform for managing servers, applications, and databases. The flaw allows an unauthenticated remote attacker to forge a valid GitHub webhook signature and trigger arbitrary deployments on any affected Coolify instance where a webhook secret was never explicitly configured. It carries a CVSS v3.1 base score of 7.5 (High) and is fixed in v4.0.0-beta.474.

Technical details

  • Root cause: Coolify’s manual_webhook_secret_github field — used as the HMAC key to validate incoming GitHub webhook requests — is a nullable database column with no default value. Newly created applications therefore have a null webhook secret. PHP’s hash_hmac() function silently coerces a null key to an empty string '', causing the server to compute hash_hmac('sha256', $payload, '') — a fully deterministic value that any attacker can independently reproduce without any knowledge of a secret.
  • Affected components: The same null-coercion issue affects the Bitbucket and Gitea webhook controllers (app/Http/Controllers/Webhook/Bitbucket.php, app/Http/Controllers/Webhook/Gitea.php) in addition to the primary GitHub controller (app/Http/Controllers/Webhook/Github.php).
  • Trigger conditions: An application created in Coolify without an explicitly set webhook secret (the default state for new applications) is vulnerable. No authentication, no credentials, and no prior knowledge of the target instance are required.
  • Attack vector: The attacker computes hash_hmac('sha256', <arbitrary_payload>, ''), submits it as the X-Hub-Signature-256: sha256=<hash> HTTP header, and sends the forged webhook request to the Coolify instance’s publicly reachable webhook endpoint.
  • Impact: Successful exploitation allows an unauthenticated attacker to trigger deployments on managed servers. Depending on the deployment configuration, this can result in unauthorized code execution on infrastructure managed by Coolify, exposure of SSH keys, or disruption of running services.

Affected software

  • Coolify (coollabsio/coolify): all versions prior to 4.0.0-beta.474

Severity

  • CVSS v3.1 Base Score: 7.5 (High)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N

Mitigation and recommended actions

  • Immediate patch: Upgrade Coolify to v4.0.0-beta.474 or later. The fix (PR #9652) strengthens HMAC signature verification, auto-generates cryptographically random secrets for new applications, backfills existing applications that have a null secret with encrypted values, and rejects webhook deliveries when no secret is configured.
  • If immediate patching is not feasible: Manually set a strong, random webhook secret for every existing Coolify application via the application settings. Additionally, restrict network access to the Coolify instance’s webhook endpoint (default port 8000) at the firewall or reverse-proxy level to trusted IP ranges only (e.g., GitHub’s published webhook IP ranges).

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
