Machine-written summary

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

Jackson Databind (Maven com.fasterxml.jackson.core:jackson-databind) versions 2.6.0 up to 2.6.7.4, 2.7.0 up to 2.9.10.7, and 2.10.0 up to 2.10.5.1 are affected. The source gives few details on how the XML external entity flaw is triggered, but it allows XXE attacks, which can affect data integrity. Upgrade to 2.6.7.4, 2.9.10.7, or 2.10.5.1, depending on your release line.
