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limits.","severity":"medium","score":5.4,"published":"2026-10-27T05:52:24.709Z","modified":"2026-10-27T05:52:24.709Z","withdrawn":false,"knownExploited":false,"affected":[],"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"],"sources":[{"name":"CVE","id":"CVE-2026-117469","modified":"2026-10-27T05:52:24.709Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-117469"}],"assessments":[{"source":"esaqa","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","score":5.4}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T23:20:36.067Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
