Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The vLLM package, versions 0.7.0 up to 0.9.0 (not including 0.9.0), hashes PIL images using only raw pixel bytes, so images with different sizes or modes but identical pixel data can produce the same hash. The source does not describe a remote attack path in detail, but it says this can cause incorrect cache hits and possible data leakage. Upgrade vLLM to version 0.9.0 or later; no workaround is listed.
