Lakefs

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.

lakeFS is an open-source tool that transforms object storage into a Git-like repositories. Prior to 1.77.0, the local block adapter (pkg/block/local/adapter.go) allows authenticated users to read and write files outside their designated storage boundaries. The verifyRelPath function used strings.HasPrefix() to verify that requested paths fall within the configured storage directory. This check was insufficient because it validated only the path prefix without requiring a path separator, allowing access to sibling directories with similar names. Also, the adapter verified that resolved paths stayed within the adapter's base path, but did not verify that object identifiers stayed within their designated storage namespace. This allowed attackers to use path traversal sequences in the object identifier to access files in other namespaces. Fixed in version v1.77.0.

lakeFS is an open-source tool that transforms object storage into a Git-like repositories. LakeFS's S3 gateway does not validate timestamps in authenticated requests, allowing replay attacks. Prior to 1.75.0, an attacker who captures a valid signed request (e.g., through network interception, logs, or compromised systems) can replay that request until credentials are rotated, even after the request is intended to expire. This vulnerability is fixed in 1.75.0.

lakeFS is an open-source tool that transforms object storage into a Git-like repositories. In versions 1.69.0 and below, missing authentication in the /api/v1/usage-report/summary endpoint allows anyone to retrieve aggregate API usage counts. While no sensitive data is disclosed, the endpoint may reveal information about service activity or uptime. This issue is fixed in version 1.71.0 . To workaround the vulnerability, use a load-balancer or application level firewall in order to block the request route /api/v1/usage-report/summary.

lakeFS is an open-source tool that transforms your object storage into a Git-like repository. In affected versions an authenticated user can crash lakeFS by exhausting server memory. This is an authenticated denial-of-service issue. This problem has been patched in version 1.50.0. Users on versions 1.49.1 and below are affected. Users are advised to upgrade. Users unable to upgrade should either set the environment variable `LAKEFS_BLOCKSTORE_S3_DISABLE_PRE_SIGNED_MULTIPART` to `true` or configure the `disable_pre_signed_multipart` key to true in their config yaml.
