On December 23, 2024, the TRIAD team from CloudSEK identified critical security issues in Postman, a popular platform for developing and testing APIs. Over 30,000 public workspaces were found leaking sensitive information like passwords, API keys, and access tokens.
The leaks impacted organizations across various industries, including healthcare, financial services, and sports brands. High-profile platforms like GitHub, Slack, and Salesforce were affected. This exposure allows hackers to gain unauthorized access, steal data, and conduct fraudulent activities.
Common causes of these leaks include misconfigured access controls, unintentional sharing of data, and storing sensitive information in plain text. For example, public repositories may accidentally include passwords or keys, making them visible to anyone online.
These breaches can lead to financial losses, reputation damage, and security risks. Experts recommend using secure practices such as encryption, environment variables, rotating passwords regularly, and verifying access settings to prevent such exposures.
Postman has since introduced measures to address this issue. The platform now alerts users if sensitive data is detected in public workspaces and allows them to move such workspaces to private or team settings. Additionally, Postman is actively removing public workspaces containing exposed secrets, notifying their owners beforehand.
