{"id":"GHSA-2h46-9x5w-4wf7","summary":"Entire CLI: Path traversal in checkpoint session metadata allows arbitrary file write during resume/rewind","details":"### Impact\n\nA 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.\n\nThe 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.\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.","aliases":["GO-2026-5063"],"modified":"2026-06-25T18:56:38.830629248Z","published":"2026-06-19T15:00:01Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-22","CWE-73"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-06-19T15:00:01Z"},"references":[{"type":"WEB","url":"https://github.com/entireio/cli/security/advisories/GHSA-2h46-9x5w-4wf7"},{"type":"WEB","url":"https://github.com/entireio/cli/pull/1365"},{"type":"WEB","url":"https://github.com/entireio/cli/pull/1449"},{"type":"PACKAGE","url":"https://github.com/entireio/cli"}],"affected":[{"package":{"name":"github.com/entireio/cli","ecosystem":"Go","purl":"pkg:golang/github.com/entireio/cli"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.7.7"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 0.7.6","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-2h46-9x5w-4wf7/GHSA-2h46-9x5w-4wf7.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:L/VA:N/SC:N/SI:H/SA:H"}]}
