CVE-2026-90451

What's the vulnerability?

An example environment-configuration file ships with a fixed, publicly-known secret value used to sign authentication cookies for a bundled packet-analysis component. A deployment that copies this example file into active configuration without running the setup routine that regenerates the value will use the known default, allowing an attacker aware of the default to forge valid authentication cookies for that component.

Recommended remediation

  1. Inventory all assets running the affected vendor and product, including shadow IT and third-party hosted instances.
  2. Apply the vendor patch or mitigation referenced in the advisories below. Where no patch exists, isolate the asset or restrict network exposure.
  3. Hunt for indicators of prior compromise — exploitation of this class of bug often predates public disclosure.
  4. Deploy detections for the exploit primitives (network signature, EDR rule, WAF rule) and re-test after remediation.
