Description Vladimir Vasilev 2026-10-06 08:02:17 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.

PeaZip before 11.3.0, in a non-default configuration, is vulnerable to OS command injection via a filename in an archive because "quotation character already used in the string" is mishandled.

Comment 1 Artur Frenszek-Iwicki 2026-10-06 08:18:29 UTC

> PeaZip before 11.3.0
PeaZip in Fedora 43 has already been updated to v11.3.0.
