Keyapi Pinterest

Security checks for vulnerabilities and agentic risk

Overview

The skill fits its Pinterest API purpose, but its credential persistence and broad helper file/API options deserve user review before installation.

Install only if you are comfortable with a KeyAPI token being stored in a shell profile as plaintext and with the helper scripts making live KeyAPI requests. Prefer setting KEYAPI_TOKEN only for the current shell session, avoid passing tokens in command arguments, do not let untrusted prompts choose --profile, --body-file, --image-file, or --output-file paths, and review generated commands before running them.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The script writes a bearer token into the user's shell profile for persistent reuse, but it does so immediately after input collection without an explicit confirmation step before modifying a startup file. Persisting secrets in profile files increases exposure to accidental disclosure through backups, dotfile sync, local file reads, or later inspection, and automatic shell startup loading broadens the blast radius if the host is shared or compromised.
Content: No source excerpt is available for this finding.

Description-Behavior Mismatch

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The presence of --image-file and --image-field support enables construction of base64 image upload payloads, which is inconsistent with a skill described only for discovery and analysis of Pinterest data. This hidden capability broadens the action surface and could let an agent submit content or invoke undocumented image-processing endpoints under the guise of a read-only tool.
Content: No source excerpt is available for this finding.

Description-Behavior Mismatch

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The script allows callers to supply arbitrary HTTP methods and JSON bodies, so it can perform write/delete actions against the KeyAPI Pinterest backend rather than being limited to read-only discovery. That exceeds the stated skill purpose and creates a capability mismatch: a user or upstream agent expecting passive analysis could be induced to modify data or trigger side effects through this wrapper.
Content: No source excerpt is available for this finding.

Context-Inappropriate Capability

Low

Category: Not specified by scanner
Confidence: 87% confidence
Finding: The manifest describes Pinterest data discovery and analysis, but this code inspects local shell profile files such as .zshrc, .bashrc, .profile, or PowerShell profile files to extract KEYAPI_TOKEN. While credential lookup may be convenient implementation support, reading arbitrary profile files is not part of the user-facing stated purpose of the skill.
Content: No source excerpt is available for this finding.
