This allows one to change permissions of files or folders outside of the server container by making symlinks to existing files in the host and then chmoding it.","affected":[{"package":{"name":"github.com/pterodactyl/wings","ecosystem":"Go","purl":"pkg:golang/github.com/pterodactyl/wings"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.11.9"},{"fixed":"1.12.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-rhq6-9rgh-v45c/GHSA-rhq6-9rgh-v45c.json"}}],"references":[{"type":"WEB","url":"https://github.com/pterodactyl/wings/security/advisories/GHSA-rhq6-9rgh-v45c"},{"type":"PACKAGE","url":"https://github.com/pterodactyl/wings"}],"database_specific":{"cwe_ids":[],"github_reviewed":true,"github_reviewed_at":"2026-06-26T20:53:00Z","nvd_published_at":null,"severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:N"}]} |
