Jira Metric

Security checks for vulnerabilities and agentic risk

Overview

This Jira helper mostly matches its stated purpose, but it includes an undocumented command that can send Jira worklog-derived data to any URL set in the environment.

Review before installing. Use only a least-privilege Jira API token, set JIRA_URL only to your trusted HTTPS Jira tenant, avoid leaving JIRA_BOARD empty unless broad project access is intended, and do not set JIRA_METRICS_URL unless you intentionally want Jira-derived metrics sent to that destination. The hidden metrics command should be removed or clearly documented and constrained before routine use.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Context-Inappropriate Capability

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

Allowing JIRA_METRICS_URL to control an outbound POST destination creates an unjustified external export path for Jira-derived data. An attacker or misconfigured environment could direct the script to send internal productivity and issue-count information to an arbitrary external host, enabling unauthorized disclosure.

Intent-Code Divergence

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

The script is presented as a Jira issue/worklog helper, but the metrics command additionally posts derived Jira worklog data to an arbitrary URL from JIRA_METRICS_URL. That hidden secondary data flow can leak potentially sensitive operational metadata outside Jira without clear disclosure or restriction, which is especially risky in an agent skill where users may invoke commands based on the advertised help text.

Missing User Warnings

Confidence
88% confidence
Finding

The skill documents commands that can modify Jira state (status changes, assignment, comments, issue creation, and worklog logging) and commands that can retrieve organization-wide worklog information, but it does not warn users about side effects, required authorization scope, or privacy implications. In an agent setting, this increases the risk of unintended ticket changes or over-broad retrieval of employee activity data because a user may invoke these commands without understanding their impact.

External Transmission

Category
Data Exfiltration
Confidence
70% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The metrics command performs silent network transmission of derived worklog data with no user-facing notice at invocation time. Even though the payload is aggregated, it still reveals internal activity levels and issue counts, and the lack of transparency increases the risk of unintentional data leakage in automated or delegated use.

External Transmission

Medium
Category
Data Exfiltration
Confidence
99% confidence
Finding

This line posts collected metrics to JIRA_METRICS_URL, an arbitrary external endpoint, creating a direct exfiltration channel from Jira-derived data to any host specified in the environment. In the context of an agent skill, environment variables may be influenced by deployment or other components, making this more dangerous because the script silently exports data outside the expected Jira boundary.
