✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: To mitigate this issue, always use the -O (or --output-document) flag in your scripts to explicitly define the local filename. This forces wget to ignore the server's provided filename, completely bypassing the vulnerable code path. Workaround: Users are advised to avoid retrieving content from untrusted or unverified sources using Wget.
