Prior to 4.1fix, modules/modules.py's write_txt, write_csv, write_json, and (commented-but-shipping) scan_file helpers open their output as open(f\"{user}.<ext>\"), where user comes unsanitized from the -u CLI flag or any line of a -U usernames file. A username that contains path-separator sequences (.., /, \\, or an absolute path) causes tookie-osint to write the scan output to an arbitrary path the invoking user has write permission for. This vulnerability is fixed in 4.1fix.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":6.7},"cvss_v3":null,"cwes":["CWE-22","CWE-73"],"references":["https://github.com/Alfredredbird/tookie-osint/security/advisories/GHSA-rp68-wfv6-3cq3","https://github.com/Alfredredbird/tookie-osint/security/advisories/GHSA-rp68-wfv6-3cq3"],"products":[],"source":"nvd","synced_at":"2026-10-26T18:27:13.530666824+00:00"},"epss":{"cve":"CVE-2026-42866","score":0.00145,"percentile":0.03705,"date":"2026-10-26"},"kev":null,"osv":[],"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).
