Almost two years ago, back in June 2018, @SpecterDev released a viable jailbreak solution for the Sony PlayStation 4. The PlayStation 4's homebrew scene has been muted since then, however, with no real headway. Thankfully, though, all of that may be set to change soon.
Popular "hackerman" @theflow0 has announced on Twitter that he has discovered a new vulnerability on the PlayStation 4. According to the security engineer, the vulnerability is valid up until firmware version 6.20, and he has advised interested owners to not update past that software version if they're interested in the imminent kernel exploit.
While there have been a number of false dawns in the PlayStation 4's homebrew scene, this appears to have some real legs to it. For one, @theflow0 is a known developer, and his work on the PlayStation Vita is very well-documented. We'd be surprised if a kernel exploit wasn't released in the near future; at least sometime this year.
A kernel exploit would quickly be followed by a full jailbreak release, and the fact that it's valid for firmware v6.20 is sure to be met with anticipation by fans, as v6.20 was released in December 2018 and likely supports games like Sekiro: Shadows Die Twice and Days Gone.
I didn't have any vulnerabilities when I wrote that. Now I have. 3 days later :)
