3 security issues in sid high

There are 3 open security issues in sid.

3 important issues:

CVE-2026-2659: 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-2026-2661: A security flaw has been discovered in Squirrel up to 3.2. This affects the function SQObjectPtr::operator in the library squirrel/sqobject.h. The manipulation results in heap-based buffer overflow. The attack needs to be approached locally. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2021-41556: 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.

The VCS repository is not up to date, push the missing commits. high

vcswatch reports that the current version of the package is not in its VCS.
Either you need to push your commits and/or your tags, or the information about the package's VCS are out of date. A common cause of the latter issue when using the Git VCS is not specifying the correct branch when the packaging is not in the default one (remote HEAD branch), which is usually "master" but can be modified in salsa.debian.org in the project's general settings with the "Default Branch" field). Alternatively the Vcs-Git field in debian/control can contain a "-b <branch-name>" suffix to indicate what branch is used for the Debian packaging.

https://salsa.debian.org/api/v4/projects/wolff-guest%2Fsquirrel3.git%2F API request failed: 404 Not Found at /srv/qa.debian.org/data/vcswatch/vcswatch line 410.
