Read full description
A security issue was discovered in Kubernetes where under certain conditions, an unauthenticated attacker with access to the pod network can achieve arbitrary code execution in the context of the ingress-nginx controller. This can lead to disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)
CVSS 9.8 (CRITICAL)

HYPE SCORE
0.0/10
REALITY · THREAT PRIORITY
6.3/10
General review priority; not probability

Evidence confidence: PoC published; attacks unconfirmed

Why this priority?
  • Technical severity: CVSS 9.8: +3.43
  • Fresh EPSS: 99.40%: +2.48
  • Published PoC; attacks unconfirmed: +0.40

General review priority, not probability, victim count or asset-specific risk. A range covers missing CVSS/EPSS inputs within the current evidence state.

Public exploit evidence
Evidence context and dated references

Reality is general threat/review priority, combining observed exploitation, CVSS severity and fresh EPSS. Evidence confidence is separate. This is not calibrated risk, a victim count or an asset-specific assessment. A range reflects missing numeric inputs.
