✅ 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: Avoid using Wget's Metalink options (--input-metalink and --metalink-over-http) when downloading from untrusted or unverified servers. Since Metalink processing must be explicitly requested, omitting these options avoids the vulnerable code path entirely. 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.
