Arbitrary file read via path traversal
Published Jun 19, 2023 · Updated Dec 11, 2024
Path traversal in Lightdash before 0.510.3 allows remote attackers to read arbitrary server files through crafted file endpoint paths. The CSV and Slack-image routes join attacker-controlled identifiers to /tmp after checking only filename prefixes, without rejecting traversal sequences or enforcing .csv and .png extensions. No authentication or user interaction is required, and successful exploitation discloses files readable by the Lightdash server process.
