Entire CLI: Path traversal in checkpoint session metadata allows arbitrary file write during resume/rewind

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Entire CLI hooks into Git workflows to capture AI agent sessions. Prior to version 0.7.7, a path traversal vulnerability in Entire CLI allows an attacker with push access to the checkpoints repository to craft malicious checkpoint metadata that causes entire session resume or entire checkpoint rewind to write attacker-controlled transcript data outside of the expected session directory. The issue occurs because checkpoint metadata is fetched from the remote entire/checkpoints/v1 branch and the SessionID field was used to construct filesystem paths without validation in the restore path. A malicious SessionID containing absolute paths or path traversal sequences could cause arbitrary files on the victim’s machine to be overwritten. This issue has been patched in version 0.7.7.

### Impact A path traversal vulnerability in Entire CLI allows an attacker with push access to the checkpoints repository to craft malicious checkpoint metadata that causes `entire session resume` or `entire checkpoint rewind` to write attacker-controlled transcript data outside of the expected session directory. The issue occurs because checkpoint metadata is fetched from the remote `entire/checkpoints/v1` branch and the `SessionID` field was used to construct filesystem paths without validation in the restore path. A malicious `SessionID` containing absolute paths or path traversal sequences could cause arbitrary files on the victim’s machine to be overwritten. ### Patches The patched versions (`v0.7.7` or `v0.7.8-nightly.*`) observe stronger input validation and enforce traversal-resistant primitives to ensure that only descending directories can be accessed by the affected commands. ### Workarounds If upgrading immediately is not possible: - Do not run `entire session resume` or `entire checkpoint rewind` on repositories where untrusted users can push to `entire/checkpoints/v1`. - Restrict push access to shared repositories until all collaborators have upgraded. - Inspect the `entire/checkpoints/v1` branch for suspicious checkpoint metadata before resuming or rewinding. - Remove or protect shell initialization files and other sensitive user-writable files where feasible. These mitigations reduce exposure but do not fully address the vulnerability. Upgrading is recommended. ### Credits Thanks Navtej Kathuria for privately reporting this issue to the Entire Security team.
