TheFlow is teasing a possible exploit for the PlayStation 4, recommends users to stay on OFW 6.20
After cracking the PlayStation Vita wide open, and providing a litany of useful homebrew tools, it appears that TheFlow is looking to move onwards and upwards to the next Sony system: the PlayStation 4. As those in the PS4 scene are likely aware, there is a current webkit exploit for consoles on firmware 6.20, thanks to SpecterDev. According to a post made by TheFlow on Twitter, it appears that he has an exploit in the works for OFW 6.20 as well. Those interested in homebrew are being told to stay on that system version, with a vague comment of, "Also don't update past FW 6.20 if you want a kxploit". What makes this tease even more notable though, is the fact that it isn't just a webkit exploit--the term "kxploit" was specifically mentioned. While a webkit exploit is useful, a kernel exploit would allow modders to do more with a theoretical softmod, and would be the first possible kexploit available since OFW 5.05/5.07. There is very limited information as of just yet, but with a track record like TheFlow's, it'd be wise to stay on 6.20 if you're on it. As of December 2019, the latest PlayStation 4 system software version is 7.02.

UPDATE: Well, it appears he didn't actually have a vulnerability in mind when he made his first Tweet above, but after receiving a PlayStation 4 from a fellow hacker, TheFlow has confirmed he indeed does have a vulnerability for OFW 6.20.
