Vulnerabilidad · Publicado 07/08/2026 · Actualizado 08/08/2026
lakeFS, herramienta de código abierto que gestiona almacenamiento de objetos como repositorios Git, presenta una vulnerabilidad de XSS reflejado en su interfaz web que afecta versiones anteriores a 1.81.1 (edición open source) y 1.84.0 (edición enterprise). Un usuario con acceso de escritura puede inyectar HTML/JavaScript malicioso en archivos .md, comprometiendo la integridad de datos y sesiones de usuarios administrativos que visualicen el contenido afectado. El riesgo es alta en entornos LATAM donde lakeFS se utiliza en pipelines de datos y data lakes corporativos.
lakeFS is an open-source tool that transforms object storage into a Git-like repositories. Prior to version 1.81.1 of the open source edition and 1.84.0 of the enterprise edition, lakeFS Web UI renders markdown files from repository objects without sanitizing the resulting HTML. A user with write access to any repository branch can commit a `.md` object containing arbitrary HTML/JavaScript. Any other user who opens that object, or who navigates to a repository or directory containing a malicious `README.md`, executes the attacker-supplied script in their own authenticated session. lakeFS fixes the issue in v1.81.1 and lakeFS Enterprise fixes the issue in in v1.84.0. Enterprise customers using older versions can temporarily disable Markdown rendering by adding YAML to their config. No workaround exists for OSS release. Users are advised to upgrade to the latest version for both lakeFS and lakeFS-Enterprise.
