We are happy to share our ai-free (lol) research on the decade old ReDoS topic, we go through a couple findings, for example if you use IsPhoneNumber decorator in say your nestjs application, your currently trivially vulnerable to getting your server š„¶

Iāll be authoring pwn challenges for @citeflag CTF this year.
Registrations are open, qualifiers start April 3rd, and there will be prizes for the winners.
We achieved a guest-to-host escape by exploiting a QEMU 0-day where the bytes written out of bounds were uncontrolled.
Full breakdown of the technique, glibc allocator behavior, and our heap spray/RIP-control primitive ā
