Title
Squirrel sqfuncstate.cpp PopTarget out-of-bounds
Summary
A vulnerability was determined in Squirrel up to 3.2. Affected by this vulnerability is the function SQFuncState::PopTarget of the file src/squirrel/squirrel/sqfuncstate.cpp. Executing a manipulation of the argument _target_stack can lead to out-of-bounds read. It is possible to launch the attack on the local host. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.

CVE-2021-41556 (GCVE-0-2021-41556)
Vulnerability from cvelistv5 – Published: 2022-07-28 20:41 – Updated: 2026-05-29 18:48
VLAI
Summary
sqclass.cpp in Squirrel through 2.2.5 and 3.x through 3.1 allows an out-of-bounds read (in the core interpreter) that can lead to Code Execution. If a victim executes an attacker-controlled squirrel script, it is possible for the attacker to break out of the squirrel script sandbox even if all dangerous functionality such as File System functions has been disabled. An attacker might abuse this bug to target (for example) Cloud services that allow customization via SquirrelScripts, or distribute malware through video games that embed a Squirrel Engine.
