{"id":"CVE-2026-73036","summary":"Bash-it barbuk Theme 3.2.0 Terminal Escape Sequence Injection via pyproject.toml","details":"Bash-it 3.2.0 contains a terminal escape sequence injection vulnerability in the barbuk theme's Python virtualenv prompt segment that allows local attackers to inject arbitrary terminal control sequences by embedding escape sequences in the requires-python field of a pyproject.toml file. 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.","modified":"2026-08-14T03:52:00.164284500Z","published":"2026-08-11T19:37:12.133Z","database_specific":{"cwe_ids":["CWE-150"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73036.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73036.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73036"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/bash-it-barbuk-theme-terminal-escape-sequence-injection-via-pyproject-toml"},{"type":"REPORT","url":"https://github.com/Bash-it/bash-it/issues/2396"},{"type":"FIX","url":"https://github.com/Bash-it/bash-it/commit/fab8f57818f28bfc6f2a81f86a58981c4ea72e5a"},{"type":"PACKAGE","url":"https://github.com/Bash-it/bash-it"},{"type":"ARTICLE","url":"https://github.com/Bash-it/bash-it/pull/2397"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bash-it/bash-it","events":[{"introduced":"0"},{"fixed":"fab8f57818f28bfc6f2a81f86a58981c4ea72e5a"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"last_affected":"3.2.0"}]}}],"versions":["v3.2.0","v3.1.1","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.0","v1.1.0","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73036.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
