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-2024-43784 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
lakeFS is an open-source tool that transforms object storage into a Git-like repository. Existing lakeFS users who have issued credentials to users who have been deleted are affected by this vulnerability. When creating a new user with the same username as a deleted user, that user will inherit all of the previous user's credentials. This issue has been addressed in release version 1.33.0 and all users are advised to upgrade. The only known workaround for those who cannot upgrade is to not reuse usernames.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/treeverse/lakefs, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/treeverse/lakefs to 1.33.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-43784 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-2024-43784 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-43784. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
