Security audit

Bitbucket

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Bitbucket connector using OOMOL's oo CLI, with clear warnings before write or destructive Bitbucket actions.

Install only if you are comfortable letting an OOMOL-connected account read and change Bitbucket resources. Confirm all write and destructive operations carefully, especially repository deletion, branch deletion, pull request merges or declines, pipeline stops, and pipeline variable changes. Use a trusted, verified oo CLI installation method rather than blindly running remote installer commands.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

The skill instructs users to install software via curl ... | bash, which downloads and immediately executes a remote script without verification. If the remote server, CDN, TLS trust chain, or distribution path is compromised, an attacker could achieve arbitrary code execution on the host running the command.

Confidence

Finding

The manifest says to use this skill for "ANY Bitbucket request" and "Whenever a task involves Bitbucket," which is an extremely broad activation condition. It does not define narrower trigger boundaries, exclusions, or negative examples, so ordinary references to Bitbucket could unintentionally activate the skill.
