- Unpinned Third-Party CLI Installed for Database Write Operations## Vulnerability Details **File Location**: `SKILL.md`, lines 16-22 **Vulnerability Type**: Unpinned third-party dependency with privileged database functionality **Risk Level**: Medium **Affected Code**: ```bash This skill requires **hologres-cli** to be installed first: pip install hologres-cli export HOLOGRES_SKILL=hologres-schema-generator ``` ```text All SQL execution depends on `hologres-cli` commands (`hologres sql run --write`, `hologres table create`). ``` ### Technical Analysis The Skill directs users to install `hologres-cli` without specifying an exact version, package hash, dependency lock file, or verified package repository. Consequently, the package and its transitive dependencies are resolved dynamically from the Python package index configured in the user's environment. Because the installed CLI is subsequently trusted to execute database write operations, compromise of the package source, a future malicious release, dependency confusion, or compromise of a transitive dependency could introduce attacker-controlled code after this Skill has been audited. Python package installation may also execute package build or installation logic with the permissions of the invoking user. No evidence demonstrates that the current `hologres-cli` package is malicious. The vulnerability is the mutable and insufficiently verified dependency installation process. ### Attack Path 1. An attacker compromises the package, one of its transitive dependencies, or the package source used by the victim. 2. The attacker publishes a malicious version that remains compatible with the unpinned installation command. 3. A user follows the Skill prerequisite and runs `pip install hologres-cli`. 4. The package manager resolves and installs the attacker-controlled release or dependency. 5. Malicious installation or runtime code executes with the local permissions of the user. 6. When the CLI is used, it may access database co ...[truncated 772 chars]
- Remediation
- ## Remediation Suggestions 1. Pin `hologres-cli` to a specifically reviewed version rather than installing the latest available release. 2. Pin all transitive dependencies through a reviewed lock file. 3. Require cryptographic hashes during installation, for example with a generated requirements file and `pip install --require-hashes -r requirements.txt`. 4. Document and enforce the authoritative package repository instead of relying on the user's unspecified Python package-index configuration. 5. Install the CLI in an isolated virtual environment or container under a non-privileged operating-system account. 6. Grant the database identity only the minimum permissions necessary for the requested schema operation. 7. Require explicit user confirmation before invoking write-capable commands such as `hologres sql run --write` or `hologres table create`. 8. Periodically review the pinned package, its publisher, provenance, signatures where available, and its complete transitive dependency tree before updating.
