Advisory LLM verdict: BLOCK
Advisory summary: Reviewed all 3 diff chunk(s). All protected required checks pass, but the visible cleanup implementation contains unsafe privileged-deletion paths. | The visible chunk adds governance metadata and focused unit coverage for artifact validation, symlink and mount-point rejection, PermissionError handling, bounded non-interactive sudo success and failure paths, and actionable remediation output. All explicitly required protected checks passed. | The visible test verifies that a permission-denied removal failure does not trigger a non-interactive sudo fallback. No unresolved code or security defects are evident in this chunk. All protected required checks passed.
Advisory findings: _batch_sudo_remove_project_artifacts treats any non-/tmp item without explicit project metadata as a project artifact and sets its project root to p.parent. That makes the containment check effectively tautological and can authorize sudo rm -rf for an arbitrary directory supplied in an item. Privileged removal must require a trusted, explicit project root and reject missing or invalid provenance.; The printed manual remediation command does not perform shell-safe quoting: paths are quoted only when they contain spaces, and embedded quotes or shell metacharacters remain active. Copying the suggested command can execute unintended shell syntax. Render every path with robust shell quoting such as shlex.quote, or avoid emitting a copyable shell command.; The supposedly strict safety validator fails open when device-stat, directory-walk, or mount enumeration operations raise errors. An unreadable subtree or failed mount inspection can therefore still reach privileged recursive deletion. Safety-check errors must reject the candidate.; Validation and sudo rm -rf are separated by a race window: after validation, an artifact or ancestor can be replaced before the privileged command acts, allowing deletion outside the validated tree. Privileged deletion needs an approach resistant to path substitution, rather than validating pathname state and later passing the same pathname to rm.
The LLM output above is advisory and was not used as the approval trust root.
Semantic review prerequisite: not_required; policy 676cb4516bbfed2a000e40b9b1b6e4a430ecc761ec546aeb53d721a1905cfdd7.

Validator approval after policy checks for exact head 1f0c74ab367804aa03dcf3bbb0d1138f30e71c17.

Ticket: ticket-108

Model: openai/cursor-auto
Reviewed diff chunks: 3
Advisory LLM verdict: BLOCK
Advisory summary: Reviewed all 3 diff chunk(s). Required checks pass, but the visible cleanup implementation has unresolved security defects in its privileged deletion and remediation paths. | The visible chunk adds focused coverage for project-artifact validation and PermissionError paths, including successful bounded non-interactive sudo removal, unavailable/failed sudo remediation, symlink rejection, project-root containment, and mount-point rejection. All protected required checks passed, as did the reported observational checks. | The visible test verifies that a permission-denied removal does not trigger a non-interactive sudo command. No unresolved code or security defects are evident in this chunk, and all protected required checks passed.
Advisory findings: _project_artifact_allowed validates paths before invoking sudo rm -rf by pathname, creating a TOCTOU vulnerability. A writable project root or intermediate directory can be replaced after validation, causing privileged pathname resolution through a newly introduced symlink or mount. Privileged deletion needs descriptor-based containment or another mechanism that preserves the validated filesystem objects through deletion.; Safety checks fail open: OSError during device checks, directory walking, or nested-entry stat() is ignored, yet the path is still approved for privileged recursive deletion. A strict validator must reject when it cannot establish same-device and no-nested-mount invariants.; When an item lacks an explicit project field, its immediate parent is accepted as the project root. This makes containment validation largely self-fulfilling and can authorize privileged deletion of arbitrary permission-denied directories represented in the candidate list, rather than artifacts tied to a trusted project root.; The printed manual remediation command does not shell-quote paths safely. It quotes only paths containing spaces, does not escape embedded single quotes, and leaves shell metacharacters or command substitutions in space-free filenames active. Copying the suggested command can execute attacker-controlled shell syntax as root.
The LLM output above is advisory and was not used as the approval trust root.
