An authenticated remote attacker with read-only access to a file could present a download transfer to the upload endpoint, obtain a signed upload URL for an attacker-selected object key, and append a chunk to the owner's file. Exploitation could upload or overwrite repository objects and consume storage, subject to transfer size, chunk-count, and lifetime limits.","state":0,"publishedAt":"2026-10-27T05:52:24.709+00:00","modifiedAt":"2026-10-27T05:52:24.709+00:00","affected":[{"ecosystem":"Vendor product","name":"Psono","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"esaqa GmbH\",\n                    \"product\": \"Psono\",\n                    \"repo\": \"https://gitlab.com/esaqa/psono/psono-server\",\n                    \"modules\": [\n                        \"Psono Server Community Edition\",\n                        \"Psono Server Enterprise Edition\"\n                    ],\n                    \"programFiles\": [\n                        \"psono/restapi/serializers/file_repository_upload.py\",\n                        \"psono/restapi/serializers/file_repository_download.py\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.0.0\",\n                            \"lessThan\": \"7.2.4\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","score":5.4,"severity":"MEDIUM"}],"references":["https://gitlab.com/esaqa/esaqa/security-advisories/-/blob/master/advisories/CVE-2026-117469.md","https://gitlab.com/esaqa/psono/psono-server/-/blob/v7.2.3/psono/restapi/serializers/file_repository_upload.py","https://gitlab.com/esaqa/psono/psono-server/-/commit/64753b19bd8d03cfbed20db575f4dccb220d9ca4","https://gitlab.com/esaqa/psono/psono-server/-/releases/v7.2.4","https://gitlab.com/esaqa/psono/psono-server"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-117469","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-117469","identifiers":["CVE-2026-117469"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
