{"cve":"CVE-2026-58499","nvd":{"published":"2026-07-10T21:17:00.197","modified":"2026-10-25T15:10:00.147","status":"Deferred","description":"EverOS is a memory runtime for agents. Prior to 1.0.1, EverOS is vulnerable to path traversal in the POST /api/v1/memory/add ingestion endpoint because the per-message sender_id field was not validated as a path-safe identifier, unlike app_id and project_id. During user-memory extraction, sender_id is used as owner_id and joined into the filesystem path where the extracted episode is persisted as a Markdown file, so a sender_id containing ../ sequences could direct writes outside the configured memory root and allow an unauthenticated caller to create or overwrite .md files at locations writable by the server process with partially attacker-influenced content. This issue is fixed in version 1.0.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","score":8.2},"cwes":["CWE-22"],"references":["https://github.com/EverMind-AI/EverOS/commit/a10cdcd197747f371b7879a32c2cc3f77471e9c2","https://github.com/EverMind-AI/EverOS/releases/tag/v1.0.1","https://github.com/EverMind-AI/EverOS/security/advisories/GHSA-c795-2g9c-j48m"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-58499","score":0.00537,"percentile":0.44956,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-c795-2g9c-j48m","url":"https://osv.dev/vulnerability/GHSA-c795-2g9c-j48m","summary":"EverOS: Path traversal in EverOS /api/v1/memory/add via unvalidated sender_id","modified":"2026-07-12T04:11:43.526213079Z","packages":[{"ecosystem":"PyPI","name":"everos","purl":"pkg:pypi/everos","ranges":["<1.0.1"],"fixed":["1.0.1"]}]}],"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).
