A malicious `SessionID` containing absolute paths or path traversal sequences could cause arbitrary files on the victim’s machine to be overwritten.\n\n### Patches\n\nThe 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. \n\n### Workarounds\nIf upgrading immediately is not possible:\n\n- Do not run `entire session resume` or `entire checkpoint rewind` on repositories where untrusted users can push to `entire/checkpoints/v1`.\n- Restrict push access to shared repositories until all collaborators have upgraded.\n- Inspect the `entire/checkpoints/v1` branch for suspicious checkpoint metadata before resuming or rewinding.\n- Remove or protect shell initialization files and other sensitive user-writable files where feasible.\n\nThese mitigations reduce exposure but do not fully address the vulnerability. Upgrading is recommended.\n\n### Credits\nThanks Navtej Kathuria for privately reporting this issue to the Entire Security team.\n\n## Affected packages\n\n- `github.com/entireio/cli < 0.7.7`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/entireio/cli 0.7.7`","depth":"sunlit","depthScore":34,"depthScoreParts":{"impact":34.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
