Description Vladimir Vasilev 2026-08-24 13:24:45 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

hashcat fails to restrict command-line options when parsing restore files, allowing attackers to inject output-redirecting options like --outfile and --potfile-path. Attackers can craft restore files with malicious options to append attacker-controlled content to arbitrary files, enabling code execution when targeting shell startup files.
