Machine-written summary

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

Remoting versions before 3206.3208, from 3248 before 3248.3250, and from 3256 before 3256.3258 are affected, as are jenkins-core versions before 2.452.4, from 2.460 before 2.462.1, and from 2.470 before 2.471. An attacker with Agent/Connect permission, or code running on an agent, can read arbitrary files from the Jenkins controller file system. Upgrade jenkins-core to 2.452.4, 2.462.1, or 2.471, or Remoting to 3206.3208, 3248.3250, or 3256.3258.
