The target must be a sibling path whose name begins with the repository path, and the user already hold permissions on it; the issue can mislead a user into operating on, or deleting, data other than the repository displayed","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:L","score":4.6},"cwes":["CWE-22"],"references":["https://gitlab.com/ikus-soft/rdiffweb","https://gitlab.com/ikus-soft/rdiffweb/-/commit/04b7096566811feb7d782e38560b44044fa91a29","https://gitlab.com/ikus-soft/rdiffweb/-/work_items/392","https://gitlab.com/ikus-soft/rdiffweb/-/work_items/393","https://gitlab.com/ikus-soft/rdiffweb/-/work_items/394"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-109118","score":0.00229,"percentile":0.13608,"date":"2026-10-25"},"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).
