{"id":"CVE-2026-58499","summary":"Path traversal in EverOS /api/v1/memory/add via unvalidated sender_id","details":"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.","aliases":["GHSA-c795-2g9c-j48m"],"modified":"2026-10-28T02:30:48.254191552Z","published":"2026-07-10T20:53:24.196Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/58xxx/CVE-2026-58499.json"},"references":[{"type":"WEB","url":"https://github.com/EverMind-AI/EverOS/releases/tag/v1.0.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/58xxx/CVE-2026-58499.json"},{"type":"ADVISORY","url":"https://github.com/EverMind-AI/EverOS/security/advisories/GHSA-c795-2g9c-j48m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58499"},{"type":"FIX","url":"https://github.com/EverMind-AI/EverOS/commit/a10cdcd197747f371b7879a32c2cc3f77471e9c2"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/evermind-ai/everos","events":[{"introduced":"0"},{"fixed":"a10cdcd197747f371b7879a32c2cc3f77471e9c2"}],"database_specific":{"extracted_events":[{"strategy":"StringRangeExpression","range":[{"introduced":"0"},{"fixed":"1.0.1"}],"source":"AFFECTED_FIELD"},{"range":[{"fixed":"a10cdcd197747f371b7879a32c2cc3f77471e9c2"}],"source":"REFERENCES_COMMIT"},{"range":[{"fixed":"a10cdcd197747f371b7879a32c2cc3f77471e9c2"}],"source":"REFERENCES_TAG","original_tag":"v1.0.1"},{"range":[{"introduced":"0"},{"fixed":"1.0.1"}],"source":"DESCRIPTION"}]}}],"versions":["v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-58499.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L"}]}
