# CVE-2024-31989: ArgoCD Vulnerable to Use of Risky or Missing Cryptographic Algorithms in Redis Cache

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 1.5% , percentile 74: FIRST’s model estimates a 1.5% chance of exploitation activity in the next 30 days, higher than 74% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes github.com/argoproj/argo-cd/v2 (Go) < 2.8.19, fixed in 2.8.19 ; github.com/argoproj/argo-cd/v2 (Go) >= 2.9.0-rc1, < 2.9.15, fixed in 2.9.15 ; github.com/argoproj/argo-cd/v2 (Go) >= 2.10.0-rc1, < 2.10.10, fixed in 2.10.10 ; github.com/argoproj/argo-cd/v2 (Go) >= 2.11.0-rc1, < 2.11.1, fixed in 2.11.1 . Check your lockfile, including transitive dependencies.

## What it is

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It has been discovered that an unprivileged pod in a different namespace on the same cluster could connect to the Redis server on port 6379. Despite having installed the latest version of the VPC CNI plugin on the EKS cluster, it requires manual enablement through configuration to enforce network policies. This raises concerns that many clients might unknowingly have open access to their Redis servers. This vulnerability could lead to Privilege Escalation to the level of cluster controller, or to information leakage, affecting anyone who does not have strict access controls on their Redis instance. This issue has been patched in version(s) 2.8.19, 2.9.15 and 2.10.10.

## Affected packages

- Go `github.com/argoproj/argo-cd/v2` < 2.8.19 → fixed: 2.8.19
- Go `github.com/argoproj/argo-cd/v2` >= 2.9.0-rc1, < 2.9.15 → fixed: 2.9.15
- Go `github.com/argoproj/argo-cd/v2` >= 2.10.0-rc1, < 2.10.10 → fixed: 2.10.10
- Go `github.com/argoproj/argo-cd/v2` >= 2.11.0-rc1, < 2.11.1 → fixed: 2.11.1
- Go `github.com/argoproj/argo-cd` <= 1.8.7 → fixed: none listed

## Affected products (CVE record)

- argoproj argo-cd: < 2.8.19, >= 2.9.0-rc1, < 2.9.15, >= 2.10.0-rc1, < 2.10.10, >= 2.11.0-rc1, < 2.11.1, <= 1.8.7

## Severity

- GitHub_M CVSS 3.1: 9.1 `CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.0 `CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.48% probability of exploitation activity in the next 30 days; percentile 74.
