Google Docs Exposes Staging Server Credentials in Search Results

"A developer on our team was debugging something unrelated and typed our domain into Google Search," said Siim Kostabi, co‑founder of Pageloot, describing how a staging password became public because Google had indexed a shared document.

How Pageloot discovered the indexed Google Doc

Kostabi told the PWNED column that an employee simply began typing the company domain into Google Search and the browser autocomplete suggested a staging hostname followed by what “looked like a credential string.” That suggestion pointed to a publicly accessible Google Docs URL. The document contained staging environment credentials that an outside contractor had placed in a Google Doc and set to be viewable by anyone with the link.

What the contractor did — and what they could have done instead

According to the account, the contractor needed access to staging credentials across multiple devices and chose to store them in a Google Doc. The PWNED writeup notes a series of alternatives the author suggested the developer could have used: a password manager, a paper notebook, a tattoo, or even emailing the credentials to themselves — the column cheekily observed that email “would have been smarter than what they did.” The chosen approach, however, left those credentials discoverable once the document was indexed by Google Search.

Immediate remediation by Pageloot

Once the exposed document was found, Pageloot cut the contractor’s access and rotated all of the exposed credentials. The company also implemented a specific new rule: no storing passwords on Google Docs, Slack, Notion, or other collaboration tools. Those steps are the concrete response Kostabi described to contain the exposure and reduce the chance of reuse of the leaked credentials.

A separate incident: redirected QR codes and failure to revoke access

Kostabi also recounted a related incident from a Pageloot customer, a mid‑size retailer, whose QR codes suddenly began directing users to a competitor’s site. Investigation showed a disgruntled ex‑employee’s credentials had not been revoked after they left, and that former employee used the retained access to redirect the retailer’s URLs. Kostabi said the redirections cost the retailer customers, linking the credential management lapse directly to tangible commercial harm.

What this means for technologists, procurement leaders, and customers

• Technologists and security teams: Pageloot’s response — cutting access and rotating credentials, plus an explicit ban on storing passwords in collaboration tools — illustrates steps teams will need to enforce when credentials are discovered in shared documents. Kostabi recommended “proper offboarding, access reviews, and not treating shared docs like private vaults.”
• Procurement leaders and affected enterprises: The contractor origin of the Google Doc highlights the need to vet how outside developers manage secrets and to ensure contractual and operational controls for offboarding and access revocation are in place and exercised.
• End users and customers: The retailer’s experience shows that credential mismanagement can ripple outward and directly affect customers — in that case by redirecting QR codes to a competitor and costing the company business.

Both incidents, Kostabi emphasized, were “completely avoidable with basic hygiene.” The specifics he provided — an indexed Google Doc revealing staging credentials, immediate credential rotation, an explicit ban on storing secrets in collaboration platforms, and an attacker using retained credentials to redirect QR codes — give a compact checklist of failure points and the precise mitigations Pageloot applied. Whether other organizations adopt comparable steps will determine how often such avoidable lapses recur.
