Most responsible disclosure is normally posted about sooner though. I think what the OP meant is that waiting 2 months later, and then giving the post this title, makes it seem as though it was a more recent bug
Actually I waited until we pushed Pyxio website on-line.
Since I am not native English speaker, what would be best replacement for current title?
"Post-mortem" is usually appended to titles for solved vulnerabilities, although this was 2 months ago. Maybe just timestamp it? e.g. "Facebook CSRF leading to full account takeover (Post-mortem, August 2013)"
That would imply that the Post-Mortem itself was written in August 2013, which would probably get far fewer clicks as people assume they've read about the vulnerability before.
