EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 90% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

conda-smithy is a tool for combining a conda recipe with configurations to build using freely hosted CI services into a single repository. Prior to version 3.61.0, a vulnerability in the conda-forge automated webservices allowed unintended write access to feedstock repositories through GitHub username takeover. The root cause is the use of mutable GitHub usernames as identifiers for repository invitation routing, rather than stable, immutable GitHub user IDs. Version 3.61.0 fixes the issue.
