Описание
Оригинално описание
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.
