Lightwell Security Advisory: commons-io 2.2.0.rhlw-00004

Type: advisorySources: OSV

Red Hat Lightwell has released commons-io:commons-io 2.2.0.rhlw-00004 with backported fixes for CVE-2021-29425 and CVE-2024-47554. CVE-2021-29425: In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like "//../foo", or "\\..\foo", the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus "limited" path traversal), if the calling code would use the result to construct a path value. CVE-2024-47554: Apache Commons IO: Possible denial of service attack on untrusted input to XmlStreamReader This patched artifact is a drop-in replacement for commons-io:commons-io 2.2.0 from Maven Central.
