Title
Contrast 1.8.0 before 1.24.1 Mesh CA Key Cross-Manifest Exposure via Peer Recovery
Summary
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 Attackers with write access to manifest history can replay a superseded history head so withdrawn workloads obtain trusted mesh certificates, or with the secret seed disclose the Mesh CA key.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
