Machine-written summary

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

Apache Ant (Maven package org.apache.ant:ant) versions before 1.10.9 are affected. The fixcrlf task deleted and recreated its temporary file without the restricted permissions added in 1.10.8, so an attacker who can access that file could inject modified source files into the build. Upgrade to version 1.10.9 or later.

Written 2 Nov 2026.
