Highest confirmed finding severity

Medium

3 confirmed security findings require attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Static analysis reported many high-risk patterns, but review found they are mainly markdown examples for Azure CLI, PowerShell, Azure MCP tools, KQL, and report templates. No prompt injection, credential exfiltration, obfuscated code, or malicious control flow was found. The skill remains medium risk because it guides authenticated Azure cost queries, writes local audit files, fetches official pricing pages, and may generate destructive cleanup commands that require explicit approval.

Confirmed security concerns (3)

RISK-001 Medium
SKILL.md:47-51SKILL.md:129-139SKILL.md:178-185SKILL.md:214-245
Authenticated Azure Operations Require User Oversight
The skill documents Azure CLI, PowerShell, Azure MCP, and REST commands that run against authenticated Azure subscriptions. This is legitimate for cost analysis, but it can expose subscription metadata and affect cloud resources if executed without user review.
The command examples are explicit and semantically tied to Azure cost analysis. They are not hidden or obfuscated, so the risk is operational rather than malicious.
RISK-002 Medium
references/azure-redis.md:23-27references/azure-redis.md:48-51templates/redis-detailed-cache-analysis.md:23-27SKILL.md:343-345SKILL.md:379
Destructive Cleanup Commands Are Present as Recommendations
The Redis guidance includes delete operations for failed or unused caches and the main skill includes temporary folder deletion. The skill also states that destructive operations require explicit approval, which reduces but does not remove the risk.
The file contains clear delete guidance, but it is presented as user-approved cloud cleanup rather than automatic execution. The approval requirement lowers confidence that this is a security vulnerability.
RISK-003 Medium
SKILL.md:188SKILL.md:249-251SKILL.md:300-309SKILL.md:321-336templates/redis-detailed-cache-analysis.md:15-27
Local Audit Files May Contain Sensitive Cost Metadata
The skill instructs agents to save cost query results and optimization reports in local output files. These files can contain resource IDs, subscription identifiers, costs, owner tags, and operational recommendations.
The report-writing behavior is explicit and expected for auditability. The sensitivity depends on the user environment and storage controls.

Audit model: codex

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

SKILL.md:3-10SKILL.md:121SKILL.md:379references/azure-quick-review.md:10-15references/azure-resource-graph.md:90-93
Weak Cryptography Matches Are False Positives
Static weak-cryptography hits occur on descriptive text, YAML list items, KQL examples, or safety guidance. Review found no code that computes weak hashes, disables TLS, or uses obsolete cryptographic primitives.
The cited lines are prose or query snippets, not cryptographic implementations. The only explicit cryptographic guidance found recommends TLS 1.2 minimum in the SDK reference.
Low
references/azure-redis.md:37references/azure-redis.md:41
Path Traversal Matches Are Relative Markdown Links
The two filesystem path traversal hits are relative links from the Redis reference to local report templates. They do not read arbitrary files, accept user-controlled paths, or escape a runtime sandbox.
Both instances are static markdown links to repository templates. There is no file access API or runtime path construction.
Low
SKILL.md:184SKILL.md:197SKILL.md:203-206SKILL.md:314
Hardcoded URLs Point to Official Azure Services
The network findings are official Azure Management, Azure Portal, and Azure pricing URLs used to query costs and validate prices. No evidence found of third-party callbacks, credential exfiltration, or hidden tracking endpoints.
The domains and paths are visible and match normal Azure cost-management workflows. The risk is disclosure through expected Azure API usage, not malicious network behavior.
Low
templates/redis-detailed-cache-analysis.md:49
C2 Keyword Match Is a Redis SKU Name
The C2 keyword hit is a Redis cache SKU named Standard C2 in an example report. It does not indicate command-and-control behavior or malware infrastructure.
The exact context is a Redis capacity tier in a cost report. No network beaconing, remote-control behavior, or suspicious endpoint is present.
