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
GHSA-p3f3-5ccg-83xq 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 379,145 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
Impact
What kind of vulnerability is it? Who is impacted?
When a user installs a package in dbt, it has the ability to override macros, materializations, and other core components of dbt. This is by design, as it allows packages to extend and customize dbt's functionality. However, this also means that a malicious package could potentially override these components with harmful code.
Patches
Has the problem been patched? What versions should users upgrade to?
Fixed on 1.8.0, and patched for 1.6.14 and 1.7.14 releases.
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
Previously, a materialization defined in a package that shared a name with one of the built-in materializations would be preferred by default, without user action which is surprising and makes it more difficult to detect the insecure behaviour. We've changed the default behaviour to require explicit overrides by users in 1.8.0, and provided the ability to opt-out of built-in materialization overrides in 1.6 and 1.7 via the flags.require_explicit_package_overrides_for_builtin_materializations: False configuration in dbt_project.yml
Versions older than 1.6 are EOL.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for dbt-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update dbt-core to 1.6.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p3f3-5ccg-83xq 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 GHSA-p3f3-5ccg-83xq can be triaged on real exposure rather than presence alone.
Tailored to GHSA-p3f3-5ccg-83xq. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-p3f3-5ccg-83xq in your dependencies?
O3 Security finds GHSA-p3f3-5ccg-83xq across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
