Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Storm storm-core versions 2.0.0 up to 2.6.0 (not including 2.6.0) are affected. On Unix-like systems, a temporary file created by the spout lag monitoring code can be readable by other local users, exposing any sensitive information written to it. This feature is disabled by default, and the file is deleted soon after creation. Upgrade to storm-core 2.6.0 or later.
