The latest AI-assisted security breakthrough has reached Nintendo’s current console: the Switch 2 has reportedly been jailbroken around 16 months after launch. The development follows wider security news involving a 20-year-old PHP vulnerability that was identified with AI assistance and exploited shortly after a patch became available.
WCCF Tech reports that the new method builds on a discovery made back in July. That earlier userland exploit allowed external code to run inside a particular game or application, but it did not provide a direct route to piracy.
The newer technique reportedly goes further. It can modify games, run homebrew software and download save files, creating a potential path towards unauthorised copies of commercial games. A video reposted by Centro Leaks appears to show characters including Peter Griffin and Hatsune Miku added to Mario Kart World.

How the Switch 2 jailbreak works
The person claiming responsibility says OpenAI Codex helped co-create the exploit. They describe roughly two weeks of substantial work using a complicated setup that resembles a Rube Goldberg device rather than a simple software tool.
The process depends on launching a specific backward-compatible Nintendo Switch game to trigger the earlier vulnerability. It must be repeated whenever the Switch 2 starts, making the current jailbreak tethered rather than permanent.
The eShop game used in the process has reportedly been identified publicly. That could allow Nintendo to remove it, limiting access to the technique. For now, this is not a practical, everyday piracy solution, and it remains far removed from the convenience of custom firmware.
Homebrew, piracy and Nintendo’s response
Jailbreak projects are often presented as a way to support independently made homebrew games on closed hardware. Homebrew communities do pursue that goal, but the same access can also be used to install ROMs of official releases, which is why piracy remains a major concern surrounding these exploits.
The original Nintendo Switch was compromised comparatively early through a hardware vulnerability. Because Nintendo could not correct that flaw with a firmware update, it could only address the issue in later manufacturing runs. Launch-model consoles affected by the vulnerability can still be jailbroken, and Nintendo took strong action against businesses selling consoles that had already been modified.
The Switch 2 situation is different, but it represents the platform’s first major security breach. AI systems can examine code and test possible weaknesses at a speed that would be difficult for individual researchers to match, so the technique is likely to receive further attention.
Backward compatibility creates another avenue
The Switch 2’s backward compatibility was also involved in an earlier modding incident. Soon after release, Switch 1 ROM cartridges were adapted to run older games on the newer console. Nintendo reportedly detected that activity and banned affected users from their own devices.
The current method is said to avoid Nintendo’s online checks, although that claim has not turned this tethered exploit into a permanent modification. Nintendo is expected to investigate firmware changes that could block the process, and a request for comment has been made to the company.
