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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-862"],"references":["https://gitlab.com/esaqa/esaqa/security-advisories/-/blob/master/advisories/CVE-2026-117469.md","https://gitlab.com/esaqa/psono/psono-server","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"],"products":[],"source":"nvd","synced_at":"2026-10-27T06:41:43.371740013+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
