Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Smarty versions before 3.0.0-beta4 do not apply the umask when setting file permissions. The source gives few details on how an attacker would reach the files, but it says this could let them bypass intended access restrictions through standard filesystem operations. Upgrade smarty/smarty to 3.0.0-beta4 or later; no workaround is listed.
