When a repository is opened with reduced trust (an ownership mismatch, which maps `.git/config` sections to `Trust::Reduced`), these protection settings should not be honored from the untrusted repository-local config. Because the trust filter is skipped, an attacker who controls a repository's `.git/config` on a shared filesystem can set `core.protectNTFS = false` and/or `core.protectHFS = false`, disabling the `.git` path-confusion checks that run during checkout, index creation, merge, and tree editing. On case-insensitive filesystems this lets crafted tree entries resolve to the `.git` directory and overwrite hooks or config.\n\n## Root Cause\n\nRepositories opened under `Trust::Reduced` install a section filter (`is_trusted`) so that security-relevant settings coming from an untruste","public_affected_ranges":[">= 0.88.0, <= 0.89.0"]}],"null_published_at":"2026-10-31T22:27:09.628Z","source_updated_at":"2026-10-23T20:52:29.000Z","source_disclosed_at":"2026-10-23T20:52:28.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T22:07:08.657Z"}],"next_cursor":null,"snapshot_revision":"42594"}
