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-2024-23840 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 377,636 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.

Summary
Hello 👋
goreleaser release --debug log shows secret values used in the in the custom publisher.
How to reproduce the issue:
- Define a custom publisher as the one below. Make sure to provide a custom script to the
cmdfield and to provide a secret toenv
#.goreleaser.yml
publishers:
- name: my-publisher
# IDs of the artifacts we want to sign
ids:
- linux_archives
- linux_package
cmd: "./build/package/linux_notarize.sh"
env:
- VERSION={{ .Version }}
- SECRET_1={{.Env.SECRET_1}}

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/goreleaser/goreleaser, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/goreleaser/goreleaser to 1.24.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-23840 is resolved across your whole dependency graph.
Workarounds
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-2024-23840 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-23840. 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-2024-23840 in your dependencies?
O3 Security finds CVE-2024-23840 across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
