How I found CVE-2026-33017, an unauthenticated RCE in Langflow, by reading the code
https://www.reddit.com/r/programming/comments/1rybo2x/how_i_found_cve202633017_an_unauthenticated_rce/

<!-- SC_OFF -->I wrote up a vulnerability research case study on how I found CVE-2026-33017, an unauthenticated RCE in Langflow. The key lesson was that the original problem was bigger than one vulnerable function. A dangerous execution pattern had been handled in one place, but another code path still exposed it through public flow execution. The article walks through the reasoning process, code review approach, and why “fixing the reported spot” is sometimes not enough. <!-- SC_ON --> submitted by /u/SadCryptographer4422 (https://www.reddit.com/user/SadCryptographer4422)

Help wanted

<!-- SC_OFF -->So if one were to want a computer program that can make a 3d model off of a GPS. That also can cancel out linear motion (say if one were in a train and used the GPS to draw a picture) i would want to see just the drawn thing not all of the trains linear motion blurring it out. who would be one to help me with that?
