Software development jobs are too accessible. Jobs with access to/control over millions of people's data should require some kind of genuine software engineering certification, and there should be business-cratering fines for something as egregious as completely ignoring security reports. It is ridiculous how we've completely normalised leaks like this on a weekly or almost-daily basis.
They may be part of it, but as a publicly traded company, there's got to be a at least a few people there with a fancy pedigree (not that that actually means they are good at their job or care). But if such a test existed, they presumably would have passed it.
They also have an ISO 27001 certificate (they try to claim a bunch of AWSs certs by proxy on their security page, which is ironic as they say AWS stores most of their data while apparently all uploads are on this).
That's wild. Thousands of SSNs in there. Also a lot of Fiverr folks selling digital products and all their PDF courses are being returned for free in the search results.
https://www.fiverr.com/.well-known/security.txt only has "Contact: security@fiverr.com" and in their help pages they say "Fiverr operates a Bug Bounty program in collaboration with BugCrowd. If you discover a vulnerability, please reach out to security@fiverr.com to receive information about how to participate in our program."
really bad stuff in the results. very easy to find API tokens, penetration test reports, confidental PDFs, internal APIs. Fiverr needs to immediately block all static asset access until this is resolved. business continuity should not be a concern here.

They probably wouldn't act immediately as there's no way for them to enable signing without breaking their client's site. The only cleanup you could do without that would be having google pull that subdomain I guess?
(Fiverr itself uses Bugcrowd but is private, having to first email their SOC as I did.)
This is crazy! So many tax and other financial forms out in the open. But the most interesting file I’ve seen so far seems to be a book draft titled “HOOD NIGGA AFFIRMATIONS: A Collection of Affirming Anecdotes for Hood Niggas Everywhere”. I made it to page 27 out of 63.
I found someone's manuscript, at first I thought it would scandalous to find it ghost written, but it actually is just annotations and someone proof reading it, the annotations come up in the PDF
I found the author on Amazon and the book still hasn't been released
> Moreover, it seems like they may be serving public HTML somewhere that links to these files. As a result, hundreds are in Google search results, many containing PII
It kind of is, though. Google doesn't randomly try to visit every URL on the internet. It follows links. Therefore, for these files to be indexed by Google, they need to be linked to from somewhere.

So who has more incentive to lie, fiverr or OP?

At least I'm sure LLM tools deploying code to production won't result in this happening more frequently. "Make sure it's secure. Make no mistakes."

It seems that someone sent a DMCA complaint months ago relating to this: https://lumendatabase.org/notices/53130362

You followed the correct reporting instructions.

Wow, surprised this isn't blowing up more. Leaking form 1040s is egregious, let alone getting them indexed by Google...

lots of admin credentials too, which have probably never been changed
admin passwords to dating sites, that's the stuff people get blackmailed with
How does someone's dating site password end up in Fiverr?
it's worse than you think – it's an admin password to the ~whole site~
Hopefully this can be patched soon.
Their robots file specifically has the code to disallow search engine crawling commented out - https://fiverr-res.cloudinary.com/robots.txt.

Probably not in scope but maybe https://bugcrowd.com/engagements/cloudinary will care?
This is bad.

I will say that the title is the best part
I've read worse. Better than Dan Brown!
that bar is subterranean, haha
Woah that's brutal all the important information is wild in public
This is really bad, just straight up people's income, SSN and worse just right there in the search results on Brave Search even.
this is a bad leak, appreciate the attempts at disclosure before this
They bought and.co and then dropped it. strange company
Burn it to the ground.
Just by scrolling over it that's really rough.
Loooool what a mess

This is not how Google works.
