Arbitrary file read via XSRF-TOKEN traversal
Published Oct 18, 2022 · Updated May 13, 2025
Path traversal in Lavalite 9.0.0 allows remote attackers to read arbitrary server files through a crafted XSRF-TOKEN cookie. The published proof of concept sends encoded parent-directory segments in that cookie to the password-reset endpoint, which processes the attacker-controlled path without restricting it to an intended directory. No authentication or user interaction is required, and the consequence is limited to reading files accessible to the Lavalite service account.
