From 37e27f71bc356d880c908040cd0cb68fa2c371b8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] foreach: Explicitly skip replay without iterations
As written, foreach loops with a trailing `IN` (i.e., no loop
variable(s) given) lead to an assertion error. Handle this case by
exiting early when we know the loop won't execute anything.
Fixes: #27135
CVE: CVE-2025-9301
Upstream-Status: Backport
