Critical OAuth Flaws Uncovered in Grammarly, Vidio, and Bukalapak Platforms

Critical OAuth Flaws Uncovered in Grammarly, Vidio, and Bukalapak Platforms

Oct 25, 2023
Critical security flaws have been disclosed in the Open Authorization (OAuth) implementation of popular online services such as Grammarly, Vidio, and Bukalapak, building upon previous shortcomings uncovered in  Booking[.]com and Expo . The weaknesses, now addressed by the respective companies following responsible disclosure between February and April 2023, could have allowed malicious actors to obtain access tokens and potentially hijack user accounts. OAuth is a  standard  that's commonly used as a mechanism for cross-application access, granting websites or applications access to their information on other websites, such as Facebook, but without giving them the passwords. "When OAuth is used to provide service authentication, any security breach in it can lead to identity theft, financial fraud, and access to various personal information including credit card numbers, private messages, health records, and more, depending on the specific service being attacked," Sa...

Critical Flaw in Grammarly Spell Checker Could Let Attackers Steal Your Data

Feb 06, 2018
A critical vulnerability discovered in the Chrome and Firefox browser extension of the grammar-checking software Grammarly inadvertently left all 22 million users' accounts, including their personal documents and records, vulnerable to remote hackers. According to Google Project Zero researcher Tavis Ormandy, who discovered the vulnerability on February 2, the Chrome and Firefox extension of Grammarly exposed authentication tokens to all websites that could be grabbed by remote attackers with just 4 lines of JavaScript code. In other words, any website a Grammarly user visits could steal his/her authentication tokens, which is enough to login into the user's account and access every "documents, history, logs, and all other data" without permission. "I'm calling this a high severity bug, because it seems like a pretty severe violation of user expectations," Ormandy said in a vulnerability report . "Users would not expect that visiting a we...
The Identities Behind AI Agents: A Deep Dive Into AI and NHI

The Identities Behind AI Agents: A Deep Dive Into AI and NHI

Apr 10, 2025AI Security / Enterprise Security
AI agents have rapidly evolved from experimental technology to essential business tools. The OWASP framework explicitly recognizes that Non-Human Identities play a key role in agentic AI security. Their analysis highlights how these autonomous software entities can make decisions, chain complex actions together, and operate continuously without human intervention. They're no longer just tools, but an integral and significant part of your organization's workforce. Consider this reality: Today's AI agents can analyze customer data, generate reports, manage system resources, and even deploy code, all without a human clicking a single button. This shift represents both tremendous opportunity and unprecedented risk. AI Agents are only as secure as their NHIs Here's what security leaders are not necessarily considering: AI agents don't operate in isolation . To function, they need access to data, systems, and resources. This highly privileged, often overlooked acces...
