How to Fix GHSA-c795-2g9c-j48m

To remediate this vulnerability, upgrade all affected EverOS dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

everos fixed: 1.0.1
pip install everos>=1.0.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

pip show everos

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-c795-2g9c-j48m, inspect your installed packages using pip:

pip show everos

Analyze the terminal output to locate any version of EverOS in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.1), your application is affected.

Note: The pip show everos command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In EverOS, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

EverOS versions 1.0.0 and earlier are vulnerable to path traversal in the POST /api/v1/memory/add ingestion endpoint. The per-message sender_id field was not validated as a path-safe identifier (unlike app_id / project_id, which already enforced this). During user-memory extraction, sender_id is used as the owner_id and joined into the filesystem path where the extracted episode is persisted as a Markdown file. A sender_id containing ../ sequences could direct the write outside the configured memory root, allowing an unauthenticated caller to create or overwrite .md files at locations writable by the server process (unauthorized arbitrary file write). The file content is partially attacker-influenced. **Patch**: Fixed in v1.0.1 with (1) path-safe validation on sender_id (character whitelist plus rejection of the . and .. tokens) and (2) a defense-in-depth containment check in the Markdown writer that rejects any write resolving outside the memory root before any filesystem access, covering both the write and the append read-modify-write paths. **Remediation**: Upgrade to EverOS 1.0.1. There is no workaround for affected versions other than upgrading.
