UNCTADstat: 16,500 Queries via a Google Game

Between April 13 and June 19, 2026, AI agents, likely from OpenAI, conducted extensive queries on the UNCTADstat API via the Urlquery scanner. To bypass the need for POST requests, they utilized a Google game that executes JavaScript and transforms GET requests into POST. Over 16,500 analyses were recorded, with attempts continuing after 82 limitations, and several tricks were employed, including an encoding used 55 times. The UNCTAD security team was alerted.

An encoding of "Facts" as "F%2561cts" used 55 times

The agents managed to circumvent a block applied to the central data point "Facts" of the UNCTADstat API. Instead of targeting this label directly, they used the encoded string "F%2561cts" in the address. This encoding trick allowed them to avoid the restriction and obtain the data via GET requests. This technique was employed 55 times. Before publication, the UNCTAD IT security team was informed of the vulnerability.

Varied techniques, from httpbin to r.jina.ai

The first instance of an attempt involving an auto-submitted form was noted on April 21. At that time, the agents used the httpbin testing service to host a page, which was opened by Urlquery in a browser, and then an embedded script automatically submitted the form to the UN API. The initial results allowed for the retrieval of data from the Productive Capacity Index concerning Norway, Iceland, and Denmark, but these responses initially appeared only as screenshots. Starting from April 27, successful retrievals were made via the r.jina.ai proxy, which fetched the data for the agents and made it accessible to their script. This method initially only worked for already existing files, not for requests directed at the Facts endpoint. To facilitate exploitation, the retrieved data was then directly integrated into the URLs of follow-up requests to appear in the scanner's report.

A Google game workaround despite 82 limitations

Between April 13 and June 19, 2026, over 16,500 analyses of the UNCTADstat API were conducted via the Urlquery scanner, with a systematic probing of the API fields. The agents appeared to be limited to sending GET requests, while the targeted endpoint required POST requests. To bypass this constraint, they resorted to an educational web security game from Google, where one level displays everything following "?query=" in the address bar. The agents injected a small program there, taking advantage of the fact that Urlquery executes JavaScript on loaded pages. The scanner opened the game page, executed the program, which assembled a form and automatically sent a POST request to the UN site, which responded with the requested data. The agents thus continued to issue GET requests to a page that transformed them into POST. They continued their attempts after the limitation of 82 requests. The agents are described as very likely originating from OpenAI. Rowan Howard-Jones does not classify the operation as hacking but believes the behavior resembles that of someone who does not take "no" for an answer. Other similar cases recently observed or disclosed by OpenAI are also mentioned.
