Hustler Words – A recent investigation by cybersecurity firm UpGuard has unearthed a significant security vulnerability within the development platform Supabase, revealing that thousands of its hosted databases are inadvertently making vast quantities of personal data accessible online. The findings underscore a growing concern in the fast-paced world of application development, where convenience can sometimes overshadow critical security measures.
UpGuard informed hustlerwords.com that its researchers identified approximately 16,000 databases containing some level of exposed personal data while being managed by Supabase. The platform, which enables web and app developers to store and operate their databases, achieved a $10 billion valuation earlier this year, largely driven by its popularity among developers building "vibe-coded" applications. However, Supabase has previously drawn scrutiny regarding its approach to user security, with numerous documented instances where users have either misconfigured or unwittingly left their databases vulnerable to the broader internet, sometimes involving millions of records.
The research critically highlights how rapidly developed applications and websites can inadvertently leak sensitive information due to fundamental misconfigurations and inadequate security practices. While AI tools streamline the creation of apps and websites, the resulting code may harbor inherent security vulnerabilities, or developers might overlook critical security configurations required for secure deployment.

Historically, a significant number of data breaches have stemmed from improperly configured storage servers, databases, and websites. Such lapses have led to the exposure of sensitive military communications, immigration and visa applications, classified government files, hundreds of thousands of driver’s license scans, and children’s personal information. The current surge in AI-driven development appears to be contributing to a fresh wave of data exposures, with many now linked to Supabase as its usage for data storage proliferates.
UpGuard’s investigation aimed to quantify the scale of data exposure across the platform, uncovering publicly accessible identifiable information such as names, addresses, phone numbers, and user passwords. A smaller, but still concerning, number of authentication tokens were also surfaced.
The firm detailed that the compromised databases contained diverse datasets, including confidential communications from an Indian adult streaming platform, thousands of vehicle license plates from a U.S. valet service, and contact details for clients of an immigration and relocation service. One database was identified as belonging to the consulate of an African government based in France, while another was utilized by a virtual SIM farm designed to intercept text messages for one-time passcode verification – a common tactic preceding scams and phishing attacks.
While the majority of these exposed datasets were identified in the United States, UpGuard emphasized that this is a global issue. These findings build upon earlier research that similarly uncovered a range of exposed databases hosted on Supabase, including those by Y Combinator startups and other popular applications.
Supabase has implemented various platform enhancements over time, including strengthening its infrastructure and refining user access controls for databases.
When contacted for comment, Supabase’s Chief Information Security Officer, Bil Harmer, stated that while the company had not yet reviewed UpGuard’s specific research, their projects are inherently "secure by default." Harmer underscored security as a mutual responsibility shared between Supabase and its clientele. He elaborated, "We furnish secure defaults and comprehensive tooling, while customers retain control over the configuration of their individual projects." Harmer added that Supabase proactively informs affected customers upon the discovery of security vulnerabilities. He concluded, "Security at Supabase is an ongoing commitment. We are dedicated to perfecting it and will continuously strive to simplify secure development for every user."
Greg Pollock, a security researcher at UpGuard, highlighted the critical role of their findings in elevating public awareness regarding data exposure risks.
