How severe is GHSA-3m4q-ggcj-j6m4?

No CVSS score has been assigned to GHSA-3m4q-ggcj-j6m4 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-3m4q-ggcj-j6m4?

GHSA-3m4q-ggcj-j6m4 affects the following packages: github.com/projectcalico/calicoctl/v3 (Go). Ecosystems affected: Go.

How do I fix GHSA-3m4q-ggcj-j6m4?

Update github.com/projectcalico/calicoctl/v3 to 3.31.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3m4q-ggcj-j6m4 is resolved across your whole dependency graph.

How do I detect GHSA-3m4q-ggcj-j6m4 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/projectcalico/calicoctl/v3, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-3m4q-ggcj-j6m4 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-3m4q-ggcj-j6m4 actively exploited in the wild?

No public exploit code has been indexed for GHSA-3m4q-ggcj-j6m4 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.

What is the EPSS score for GHSA-3m4q-ggcj-j6m4?

GHSA-3m4q-ggcj-j6m4 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 21th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-3m4q-ggcj-j6m4?

GHSA-3m4q-ggcj-j6m4 is classified as CWE-532 (CWE-532). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

When calicoctl is invoked with --log-level=info or --log-level=debug, the client prints the full contents of its loaded connection-configuration struct to stderr in a single log line. The struct embeds every credential calicoctl uses to talk to the cluster — inline kubeconfig (with bearer token), Kubernetes API bearer token, etcd password, and inline PEM-encoded etcd client certificate and key. Any reader of that stderr stream — CI job logs, session-recording archives, shared support-ticket transcripts, or local filesystem viewers on the host that ran calicoctl — can extract these credentials with zero Kubernetes privilege. calicoctl's default log level is panic, so this issue only triggers when verbose logging is explicitly enabled.
