Last modified
CVE-2020-1945 is a medium-severity vulnerability rated 6.3/10 on the CVSS scale. Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process.. EPSS estimates a 1.79% chance of exploitation in the next 30 days.
