Machine-written summary

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

Spring REST Docs' spring-restdocs-webtestclient and spring-restdocs-restassured packages are affected in versions 4.0.0, 3.0.0 through 3.0.5, and 2.0.0.RELEASE through 2.0.8.RELEASE. An attacker who compromises a remote API, or tricks a user into documenting a malicious API, can perform an XML external entity (XXE) injection when the documentation-generating tests next run. Upgrade to spring-restdocs-webtestclient or spring-restdocs-restassured 4.0.1 or 3.0.6.
