Sources and claim methodology

  • Source referencevulncheck.com
Upstream source description

Contrast 1.8.0 before 1.24.1 contains an improper verification vulnerability in Coordinator peer recovery that fails to confirm the serving peer uses the same manifest generation. Attackers with write access to manifest history can replay a superseded history head so withdrawn workloads obtain trusted mesh certificates, or with the secret seed disclose the Mesh CA key.
