markdown ## Prerequisites This skill requires **hologres-cli** to be installed first: ```bash pip install hologres-cli export HOLOGRES_SKILL=hologres-privilegestext ### Technical Analysis The prerequisite installs `hologres-cli` without pinning a reviewed version, verifying cryptographic hashes, or specifying an explicitly trusted package index. As a result, the package and its transitive dependencies may change independently of the reviewed Skill. Python package installation may execute package-controlled build or installation logic. The resulting CLI is then trusted to perform write-capable database operations through `hologres sql run --write`. A compromised package release, dependency, package repository, or resolution path could therefore introduce arbitrary local code execution. This finding does not establish that `hologres-cli` is malicious. It identifies an unsafe and non-reproducible dependency installation process. ### Attack Path 1. An attacker compromises the `hologres-cli` distribution account, one of its transitive dependencies, or the package source used by `pip`. 2. The attacker publishes a malicious release or modifies a dependency selected by the unpinned installation. 3. A user follows the documented prerequisite and runs `pip install hologres-cli`. 4. `pip` downloads the attacker-controlled package and may execute malicious build or installation logic. 5. The installed CLI runs with the user's local privileges and may access environment variables, local files, database credentials, or authentication material available to that user. 6. Because the Skill relies on the CLI for write operations, a malicious implementation could alter SQL, execute unauthorized database commands, or exfiltrate accessible credentials and data. ### Impact Assessment S ...[truncated 646 chars]- Remediation

Remediation Suggestions
-
Pin
hologres-clito a specifically reviewed release, for example:bash python -m pip install "hologres-cli==X.Y.Z" -
Record cryptographic hashes in a requirements or lock file and install with hash enforcement:
bash python -m pip install --require-hashes -r requirements.txt -
Pin and hash all transitive dependencies, not only the top-level package.
-
Specify and document an explicitly trusted package index. Where feasible, use an internally controlled artifact repository containing reviewed package artifacts.
-
Document the expected package publisher, package name, approved version, and integrity-verification procedure to reduce dependency-confusion and package-substitution risk.
-
Install and run the CLI in an isolated virtual environment or container under a non-privileged operating-system account.
-
Use a least-privileged Hologres account for routine operations. Require separate approval and credentials for ownership changes, role administration, or superuser operations.
-
Review release changes and regenerate locked hashes before upgrading the dependency.
