Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2023-33001 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,567 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Jenkins HashiCorp Vault Plugin 360.v0a_1c04cf807d and earlier does not properly mask (i.e., replace with asterisks) credentials printed in the build log from Pipeline steps like sh and bat, when both of the following conditions are met:
-
The credentials are printed in build steps executing on an agent (typically inside a
nodeblock). -
Push mode for durable task logging is enabled. This is a hidden option in Pipeline: Nodes and Processes that can be enabled through the Java system property
org.jenkinsci.plugins.workflow.steps.durable_task.DurableTaskStep.USE_WATCHING. It is also automatically enabled by some plugins, e.g., OpenTelemetry and Pipeline Logging over CloudWatch.
An improvement in Credentials Binding 523.525.vb_72269281873 implements a workaround that applies build log masking even in affected plugins. This workaround is temporary and potentially incomplete, so it is still recommended that affected plugins be updated to resolve this issue.
As of publication of this advisory, there is no fix.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.datapipe.jenkins.plugins:hashicorp-vault-plugin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of com.datapipe.jenkins.plugins:hashicorp-vault-plugin has shipped for CVE-2023-33001 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2023-33001 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2023-33001. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-33001 in your dependencies?
O3 Security finds CVE-2023-33001 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
