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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.5},"cwes":["CWE-59","CWE-367"],"references":["https://github.com/gunthercox/ChatterBot/commit/82817b5c28bfd43e682b991bcc76e6f780726dbf","https://github.com/gunthercox/ChatterBot/pull/2445","https://github.com/gunthercox/ChatterBot/releases/tag/1.2.14","https://github.com/gunthercox/ChatterBot/security/advisories/GHSA-wvrh-2f4m-924v","https://github.com/gunthercox/ChatterBot/security/advisories/GHSA-wvrh-2f4m-924v"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-58198","score":0.00123,"percentile":0.02059,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-wvrh-2f4m-924v","url":"https://osv.dev/vulnerability/GHSA-wvrh-2f4m-924v","summary":"ChatterBot: Symlink-Following Arbitrary Write via UbuntuCorpusTrainer","modified":"2026-07-10T04:11:44.950774104Z","packages":[{"ecosystem":"PyPI","name":"chatterbot","purl":"pkg:pypi/chatterbot","ranges":["<1.2.14"],"fixed":["1.2.14"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
