Trust Assessment
image-upscaling received a trust score of 12/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 3 findings: 3 critical, 0 high, 0 medium, and 0 low severity. Key findings include Arbitrary command execution, Remote code execution: curl/wget pipe to shell, Excessive Bash permissions for 'infsh' commands.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. All layers scored 70 or above, reflecting consistent security practices.
Last analyzed on February 14, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings3
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Remote code download piped to interpreter Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/okaris/image-upscaling/SKILL.md:9 | |
| CRITICAL | Remote code execution: curl/wget pipe to shell Detected a pattern that downloads and immediately executes remote code. This is a primary malware delivery vector. Never pipe curl/wget output directly to a shell interpreter. | Static | skills/okaris/image-upscaling/SKILL.md:9 | |
| CRITICAL | Excessive Bash permissions for 'infsh' commands The skill declares `Bash(infsh *)` permission, which allows the agent to execute any command starting with `infsh`. This is an overly broad permission that could be exploited if the agent's LLM is prompted to construct malicious `infsh` commands. This could lead to unauthorized actions, data manipulation, or system compromise via the `inference.sh` CLI, depending on the capabilities of the `infsh` tool and the context in which it runs. Restrict the `Bash` permission to only the specific `infsh` subcommands and arguments necessary for the skill's intended functionality. For example, if only `infsh app run` and `infsh app list` are needed, declare permissions like `Bash(infsh app run *)` and `Bash(infsh app list *)`. Avoid using wildcard permissions (`*`) unless absolutely necessary and after a thorough security review. | LLM | SKILL.md:1 |
