Global News By Opera News

Security checks for vulnerabilities and agentic risk

Overview

This news skill is review-worthy because it asks the agent to run shell-based web requests with user-influenced inputs and to display third-party news content as safe without enough validation.

Install only if you are comfortable with the skill making external requests to the Opera News feed and with your agent using Bash for those requests. Prefer a version that uses a scoped HTTP tool, validates country/language codes, safely URL-encodes all user-controlled fields, checks returned links before displaying them, and asks before assuming a default locale.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger list contains very broad terms such as "news," "video," and "what's happening," which are likely to overlap with normal user conversation and unrelated intents. This can cause unintended skill activation and routing of user requests to this skill when the user did not explicitly ask for it, increasing the chance of inappropriate data fetching or user confusion.

Natural-Language Policy Violations

Confidence
92% confidence
Finding

Defaulting to us/en when the user's market is unclear can cause the system to infer or impose a locale without explicit user choice. While not a code-execution issue, it can lead to privacy and relevance concerns by returning location- or language-specific content the user did not request.

Natural-Language Policy Violations

Category

Confidence
91% confidence
Finding

The explicit instruction to always fall back to us/en reinforces behavior that selects a specific locale without user consent. This makes accidental mis-targeting systematic across the skill and may expose users to irrelevant or culturally incorrect content, especially for non-US users.
