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.","published":"2026-06-18T21:16:29.000Z","lastModified":"2026-10-26T11:10:00.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":7.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:L"},"cwe":["CWE-284"],"affected":[],"epss":{"score":0.0033,"percentile":0.26028,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.33%).
