Machine-written summary

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

Backpack CRUD (backpack/crud) versions 4.1.0 to before 4.1.72, 5.0.0 to before 5.6.2, 6.0.0 to before 6.8.13, and 7.0.0 to before 7.0.36 are affected. An unauthenticated remote attacker who can send crafted HTTP Host headers, and who may need several attempts because the vulnerable path only runs on a small random share of requests, can inject operating system commands that run as the web server user. Upgrade to 4.1.72, 5.6.2, 6.8.13, or 7.0.36 or later, matching your release branch.
