FB Personal Poster

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed Facebook posting helper, but it can use live account cookies and may change photo posts to Public without a user-selected audience.

Review carefully before installing. Only use this with a Facebook account and cookie file you are comfortable granting posting access to, keep dry-run on until you verify the exact post and photos, and assume photo posts may be made Public unless the skill is changed to preserve or explicitly ask for the audience.

Description-Behavior Mismatch

Medium
Confidence
95% confidence
Finding
The photo-posting flow includes logic to edit the sharing audience and switch it to Public, which exceeds the documented behavior of merely posting text and photos. In a skill that automates posting to a personal account using live session cookies, changing privacy scope can unintentionally disclose personal content much more broadly than the user intended.

Missing User Warnings

Medium
Confidence
98% confidence
Finding
The script attempts to change post visibility to Public without any explicit warning, consent, or confirmation from the user. Because this skill posts to a personal Facebook timeline and may handle private photos, silent audience expansion can cause unintended public exposure of sensitive content, which is a meaningful privacy and safety risk.
