Low risk45th percentile - higher than 45% of all known CVEs
Summary
EverOS before version 1.0.1 is vulnerable to path traversal in the POST /api/v1/memory/add endpoint. The sender_id field was not validated as a path-safe identifier, allowing an unauthenticated attacker to write or overwrite .md files outside the intended memory directory.
Risk Assessment
An attacker can create or overwrite Markdown files at any location writable by the server process, potentially modifying configuration, scripts, or application data, leading to privilege escalation or further system compromise.
Recommendation
Immediately upgrade EverOS to version 1.0.1 or later. If upgrading is not possible, implement validation of the sender_id field to reject characters like '../'.

Original NVD description (English source)
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.
