When a user navigates into a directory containing a maliciously crafted pyproject.toml, the unfiltered field value is read via awk and concatenated directly into PS1 through __prompt-command without stripping control characters, causing injected OSC or CSI sequences to be written to and interpreted by the terminal emulator on every prompt render.","epss":{"date":"2026-11-08","percentile":0.0732,"score":0.00177},"exploits":[],"kev":null,"metrics":[{"score":4.6,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},{"score":4.4,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1794146924954,"publishedAt":1786477032133,"references":[{"source":"CNA: VulnCheck","tags":["product"],"url":"https://github.com/Bash-it/bash-it"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/Bash-it/bash-it/commit/fab8f57818f28bfc6f2a81f86a58981c4ea72e5a"},{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://github.com/Bash-it/bash-it/issues/2396"},{"source":"CNA: VulnCheck","tags":["technical-description","patch"],"url":"https://github.com/Bash-it/bash-it/pull/2397"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/bash-it-barbuk-theme-terminal-escape-sequence-injection-via-pyproject-toml"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
