Real-World Exposure
github.com/treeverse/lakefsReal-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
Impact
Missing authentication in the /api/v1/usage-report/summary endpoint allows anyone to retrieve aggregate API usage counts. While no sensitive data is disclosed, the endpoint may reveal information about service activity or uptime.
Patches
Upgrade to >v1.70.1
Workarounds
Any ONE of these is sufficient to block this reporting:
- Disable usage reporting by setting configuration option
usage_report.enabledor environment variableLAKEFS_USAGE_REPORT_ENABLEDtofalse. - Using load-balancer or application level firewall - blocking the request route /api/v1/usage-report/summary.

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 1.71.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h238-5mwf-8xw8 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.
