Security audit

gladia-pre-recorded-transcription

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only skill for using Gladia's remote transcription API, with expected upload, callback, and job-management behavior but limited privacy warnings.

Before installing, confirm you are comfortable sending selected recordings or media URLs to Gladia and, when using callbacks, only use webhook endpoints you control and trust. Be careful with confidential, regulated, or personally identifying audio; enable redaction or avoid optional analysis features when not needed.

Vulnerability Patterns
  • 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
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Tool Parameter Abuse

High
Category
Tool Misuse
Confidence
80% confidence
Finding

Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill explicitly encourages sending local audio files and external URLs to Gladia's remote transcription service but does not clearly warn that the content leaves the local environment and may contain sensitive data such as conversations, PII, or regulated information. In an agent setting, this omission can cause users or downstream automation to transmit confidential media to a third party without informed consent or proper policy review.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The documentation encourages use of a callback_url for async delivery but does not clearly warn that full transcription results, which may include sensitive audio-derived content such as PII, summaries, entities, and subtitles, will be transmitted to the specified external endpoint. In this skill’s context, that omission is security-relevant because the feature is explicitly designed for processing potentially sensitive recorded audio, making accidental exfiltration to an unintended or weakly protected webhook more likely.
