Be super careful with this, you had innocent intent, but that doesn’t mitigate the fact that you potentially broke the law (and regardless of whether you did or not, that won’t stop feds busting in the door). Some places will take reports like that gratefully, others will do everything in their power to make you out to be the bad guy.

At least they cared. I found an enumeration attack on an Australian referral service where phone numbers were keys and it returned way too much personal information. Responsibly disclosed numerous times, LinkedIn contacted employees. Not even acknowledged and at last check, still open vulnerability.

Full disclosure was a thing exactly because of that.

Earlier quoted context omitted.

Under New Zealand's Crimes Act, all unauthorised access is illegal. This has been used in court to cover places where someone was not pre-approved, rather than just a policy that gives an implied acceptance. It has also been used where someone has accidentally gained access via insecured systems. I would not be so confident in stating that they did not break the law.

Any half-decent VDP will have a safe harbour clause. Otherwise ot isn't a true VDP but rather just contact details.

A security disclosure contact email is not a safe harbour clause.

PHP was blamed for a good reason: for a long time it did not by default support prepared SQL statements. You could install the mysqli extension to gain such support but that was almost never available on shared web hosts.

And every tutorial you could find on how to use PHP with a database was a tutorial on how to add SQL injection to your site.

That was the bigger problem, IMO, in that even once PDO existed and the MySQL extension was "fixed" to have prepared statements, so much of the documentation still did it wrong.

And yet similar classes of bugs still pops up today, even with what I would've assumed to be safe defaults? I'm guessing its non-standard databases or DB clients or something?

This case is more just a pure lack of sanitisation, but it's fascinating to see in 2025 still :)

The sad thing is, that at some point they truly get exposed (big leak) and your name might come up because they have nobody else to blame. I wish you the best and hope you have lawyer insurance.

Australia and New Zealand are insanely careless with personal data. I was shocked when I was asked to write my credit card details, including cvv, on a piece of paper in a beachside surfboard rental shop

Had the same experience in Namibia in 2022. First I should sent them my credit card stuff via mail. Then via a website which looked like it would automatically write my data to a mail and send it to them :D.

I used a freshly generated virtual credit card with payment amount +20$ as a limit (just to be sure).

So far, the courts have ruled that you need to be specifically approved, by name, before any works begin. There is no safe harbour here. Your policy does not overrule the law. You need a pre-existing relationship with the company, before you begin to look for vulnerabilities.

Kiwi bank is the most likely IMO. Almost 4 star and the kind of think GPT would do is leave in the Kiwi part.

I don't think so. The data returned talks about loyalty, rewards, and gift cards.

Good point

Australians are very lax on human rights, including the right to privacy.

Pine Gap is the world’s largest network tap, after all, invalidating the human rights of close to 2 billion people, every single second of the day.

The nation was bred to be so compliant. Australians are not afraid of licking boots if it means cheap avocados can be smashed.
