How severe is GHSA-7xg2-83f8-39mr?

No CVSS score has been assigned to GHSA-7xg2-83f8-39mr yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-7xg2-83f8-39mr?

GHSA-7xg2-83f8-39mr affects the following packages: github.com/karmada-io/karmada (Go). Ecosystems affected: Go.

How do I fix GHSA-7xg2-83f8-39mr?

Update github.com/karmada-io/karmada to 1.8.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7xg2-83f8-39mr is resolved across your whole dependency graph.

How do I detect GHSA-7xg2-83f8-39mr in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/karmada-io/karmada, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-7xg2-83f8-39mr if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is GHSA-7xg2-83f8-39mr actively exploited in the wild?

No public exploit code has been indexed for GHSA-7xg2-83f8-39mr yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

When was GHSA-7xg2-83f8-39mr published, and has it been updated?

GHSA-7xg2-83f8-39mr was published on January 3, 2024 and was last updated on June 28, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

What kind of vulnerability is it? Who is impacted?

The Karmada components deployed with karmadactl, karma-operator, and helm chart take Golang default cipher suites as part of the TLS protocol, which includes the insecure algorithm. Referring to https://github.com/golang/go/issues/41476#issuecomment-694914728, the 3DES algorithm vulnerability is very unlikely to be attacked. However, to address the concerns and to avoid being disturbed by the security scanner, Karmada has decided to limit the cipher suites to exclude the insecure 3DES algorithm and accordingly release this security advisory.

The components affected are：

karmada-apiserver
karmada-aggregated-apiserver
karmada-search
karmada-metrics-adapter
etcd

Patches

Has the problem been patched? What versions should users upgrade to?

From Karmada v1.8.0, when deploying Karmada with karmadactl, karma-operator, and helm chart, the default minimum TLS version of components(include karmada-apiserver, karmada-aggregated-apiserver, karmada-search, and karmada-metrics-adapter) would be set to TLS1.3 to get rid of the insecure algorithm, and set default cipher suites(TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_GCM_SHA256,TLS_RSA_WITH_AES_256_GCM_SHA384,TLS_AES_128_GCM_SHA256,TLS_AES_256_GCM_SHA384,TLS_CHACHA20_POLY1305_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256,TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305,TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305) for etcd.

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

By setting the --tls-min-version for the affected components to TLS 1.3, or explicitly setting the --cipher-suites to secure algorithms.
