Vulnerability Type: Unpinned third-party dependencies
Risk Level: Mediumjson "dependencies": { "bb-browser": ">=0.11.0" }, "pythonDependencies": { "requests": ">=2.31.0" },Technical Analysis
The project specifies
bb-browserandrequestsusing open-ended minimum-version constraints. No dependency lockfile is present in the audited project. Consequently, a future installation may resolve to a version that was not reviewed with this release.The risk is particularly relevant for
bb-browserbecause the skill invokes its executable locally and allows it to interact with a Chrome debugging endpoint. Documentation also recommends installing it globally withnpm install -g bb-browser. A compromised, malicious, or unexpectedly incompatible future release could therefore execute with the installing user's privileges.This finding does not establish that either currently published package is malicious. The vulnerability is the absence of reproducible, integrity-controlled dependency resolution.
Attack Path
- An attacker compromises a dependency maintainer account, package registry publication process, or another upstream distribution component.
- The attacker publishes a malicious version newer than the declared minimum.
- A user installs or updates the skill without a lockfile or exact version constraint.
- The package manager resolves the dependency to the malicious release.
- The dependency executes during installation or when the skill invokes
bb-browser. - The payload runs under the user's account and may access files, network resources, environment data, or the locally exposed Chrome debugging interface available to that process.
Impact Assessment
Successful exploitation could provide code execution with the privileges of the user installing or running the skill. The resulting scope may inclu ...[truncated 423 chars]

Remediation Suggestions
- Pin dependencies to exact reviewed versions, for example:
json "dependencies": { "bb-browser": "0.11.0" }, "pythonDependencies": { "requests": "2.31.0" } - Commit the appropriate lockfile, such as
package-lock.json, and use reproducible installation commands such asnpm ci. - Manage Python dependencies through a locked requirements or environment-management file containing hashes, such as:
text requests==2.31.0 --hash=sha256:<verified-package-hash> - Avoid global package installation where possible. Install
bb-browserin a project-scoped environment and invoke the locked local binary. - Configure automated dependency review and vulnerability scanning, but update versions only through reviewed pull requests.
- Verify package provenance and registry integrity before installation, and run browser-related dependencies with the minimum filesystem and network permissions required.
- Pin dependencies to exact reviewed versions, for example:
