Security Findings1
1 finding detected across 1 severity level. Each finding includes a structured evidence chain answering: WHAT, WHERE, WHY, HOW CONFIDENT, and HOW TO VERIFY.
What Was Found
Untrusted data entry point identified. A external content source at package dependency: mariadb introduces data into the processing pipeline without adequate boundary controls. The observed input pattern is Known malicious package "mariadb" found in dependency list.
This package is confirmed malicious or a known typosquat targeting legitimate packages
Dangerous operation reached. This data reaches a operating system command execution at mariadb install/postinstall hooks, where the observed operation is Malicious package "mariadb" executes arbitrary code during installation or at runtime.
Potential impact: Remote Code Execution (RCE). If exploited, an attacker could compromise server host system. Exploitability is assessed as trivial — no special conditions required.
Where in the Code
The data flow traverses 2 locations from entry point to dangerous operation. The data flows directly from source to sink with no intermediate transformations or sanitization points.
Why This Is Dangerous
Remote Code Execution (RCE). Malicious package "mariadb" executes attacker-controlled code in the build environment during npm install / pip install, potentially exfiltrating credentials or installing backdoors
Missing security controls (1): The following mitigation measures were checked during analysis and found to be absent. Each represents a defense layer that, if implemented, would reduce or eliminate the exploitability of this finding.
No protection against malicious package — it is directly listed as a dependency
"mariadb" is a confirmed malicious package or typosquat — must be removed immediately
Confidence Assessment
This finding has been assigned a confidence score of 80% (high). Confidence reflects the strength of the evidence chain: higher values indicate that the finding was confirmed through multiple independent analysis techniques (e.g., AST-based taint tracking, structural pattern matching, or cross-reference with known CVEs). Lower values indicate the finding is based on heuristic patterns that may require manual verification.
Confidence factors: The following analysis signals contributed to the final confidence score. Positive adjustments indicate corroborating evidence; negative adjustments indicate uncertainty or partial mitigation.
No input-validation found — No protection against malicious package — it is directly listed as a dependency
"mariadb" is listed in known malicious package databases
How to Verify
The following verification steps enable independent confirmation of this finding. Each step can be performed by a security reviewer, compliance auditor, or automated tooling to validate that the identified vulnerability exists and assess whether remediation has been applied.
mariadbCross-reference "mariadb" against malicious package databases (npm advisories, Snyk, Socket.dev)
"mariadb" appears in malicious package lists or is a known typosquat
