Understanding a Potential Security Flaw in Dave & Buster’s “Find the Flag” Promotion
Recently, I came across an important issue related to the ongoing “Find the Flag” contest at Dave & Buster’s Reno location, which may compromise the fairness of the game.
Here’s what I observed: Participants are invited to uncover hidden clues across the venue, with each clue corresponding to a specific date. However, a deeper look into the web page source revealed a vulnerability that could allow savvy users to access future clues prematurely.
The problem stems from how the clues’ URLs are constructed—using a predictable, date-based naming pattern. Additionally, these clue files are stored publicly without any server-side security measures. By using basic developer tools in a web browser, anyone with minimal technical knowledge can:
- Open the browser’s developer console while on the clue webpage
- Inspect the page’s source code or network requests
- Alter the date in the URL or file reference (for example, changing “clue-2025-07-16.jpg” to “clue-2025-07-17.jpg”)
- Instantly view upcoming clues ahead of schedule
This loophole explains how some users managed to find multiple clues within minutes of their official release, significantly undermining the challenge’s integrity. In contrast, I personally found a clue through honest deduction, which required genuine effort and problem-solving.
Having identified this issue, I’ve already contacted Dave & Buster’s Guest Relations team, providing detailed screenshots and explanations of the vulnerability. My intention is to give the company an opportunity to address the problem before it escalates or impacts other participants.
It remains uncertain whether this was an isolated oversight or a more intentional exploit. Regardless, transparency and quick action are essential to maintaining fair play and the event’s credibility.
Please note: I am sharing this information purely to promote awareness and encourage responsible handling of potential security vulnerabilities. I am not accusing anyone or revealing identities unnecessarily.
Let’s hope Dave & Buster’s takes corrective measures soon to preserve the fun and fairness of their “Find the Flag” challenge.
