{"id":"CVE-2026-61617","summary":"Pterodactyl Wings SFTP write path does not enforce disk quota, allowing node-wide disk exhaustion","details":"Wings is the server control plane for the Pterodactyl game-server management panel. In versions up to and including 1.13.2, the SFTP write path does not enforce a server's disk quota during a transfer, allowing a tenant with SFTP write access to a single server to exhaust the host node's physical disk and take down every server on it. Wings checks available space only once, as a boolean, when the write handle is opened, using a stale cached usage value and without knowing the size of the incoming data, and it then returns a raw, unaccounted file handle that is never re-checked as the transfer proceeds. A single upload can therefore be written without bound, far beyond the configured disk limit, until the node's disk is full, and because a server stopped for exceeding its limit is not treated as suspended, SFTP writes are still accepted even after the quota is already exceeded. This issue is fixed in version 1.13.3.","aliases":["GHSA-8j54-xcwx-597p"],"modified":"2026-08-28T03:47:07.569262238Z","published":"2026-08-26T21:56:41.379Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-400","CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61617.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61617.json"},{"type":"ADVISORY","url":"https://github.com/pterodactyl/wings/security/advisories/GHSA-8j54-xcwx-597p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61617"},{"type":"FIX","url":"https://github.com/pterodactyl/wings/commit/da1a216cfff5867fa66be32cb1edb93e37fd71ff"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pterodactyl/wings","events":[{"introduced":"0"},{"fixed":"da1a216cfff5867fa66be32cb1edb93e37fd71ff"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.13.3"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.13.2","v1.13.1","v1.13.0","v1.12.3","v1.12.2","v1.12.1","v1.12.0","v1.11.13","v1.11.12","v1.11.11","v1.11.10","v1.11.9","v1.11.8","v1.11.7","v1.11.6","v1.11.5","v1.11.4","v1.11.3","v1.7.2","v1.11.2","v1.11.1","v1.11.0","v1.11.0-rc.2","v1.11.0-rc.1","v1.7.1","v1.7.0","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.6","v1.5.5","v1.5.4","v1.5.3","v1.5.2","v1.5.1","v1.5.0","v1.4.7","v1.4.6","v1.4.5","v1.4.4","v1.4.3","v1.4.2","v1.4.1","v1.4.0","v1.3.2","v1.3.1","v1.3.0","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.1","v1.0.0","v1.0.0-rc.7","v1.0.0-rc.6","v1.0.0-rc.5","v1.0.0-rc.4","v1.0.0-rc.3","v1.0.0-rc.2","v1.0.0-rc.1","v1.0.0-beta.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-61617.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H"}]}
