CVE-2026-58198 – ChatterBot: Symlink-Following Arbitrary Write via UbuntuCorpusTrainer

CVE ID :CVE-2026-58198

Published : July 9, 2026, 7:17 p.m. | 31 minutes ago

Description :ChatterBot is a machine learning, conversational dialog engine for creating chat bots. Prior to 1.2.14, UbuntuCorpusTrainer.extract() uses a predictable home-rooted output directory (~/ubuntu_data/ubuntu_dialogs) with a check-then-create pattern followed by tar.extractall(path=self.data_path), allowing a local attacker who pre-plants a symlink at the predictable path to cause archive contents to be written through the symlink to an attacker-chosen directory. This issue is fixed in version 1.2.14.

Severity: 5.5 | MEDIUM
