A public-only token with read:repository scope can route a comparison or pull request creation through a public base repository and retrieve commit history and diffs from a private head repository accessible to the token owner. This bypasses the token's public-only restriction; it does not remove the account's underlying repository permission checks.","published":"2026-10-14T15:17:23.000Z","lastModified":"2026-10-14T16:17:52.000Z","status":"Deferred","sourceIdentifier":"88ee5874-cf24-4952-aea0-31affedb7ff2","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-863"],"affected":[],"epss":{"score":0.00341,"percentile":0.27428,"date":"2026-10-26","history":[{"date":"2026-10-15","score":0.00341,"percentile":0.26019}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.34%).
