Salt Security announced the release of its new multi-layered OAuth protection package

April 2024 by Marc Jacob

Salt Security announced the release of its new multi-layered OAuth protection package to detect attempts to exploit OAuth and proactively fix vulnerabilities. Salt is enhancing its API protection platform with a comprehensive suite of new OAuth threat detections and posture rules to address the growing challenge of OAuth exploitation. The company is the first API security vendor to launch deep OAuth threat detection capabilities, and these innovations will empower organizations to identify and mitigate malicious attempts to exploit OAuth flows, ultimately safeguarding sensitive data and user accounts.

Today, OAuth is an important part of modern authorization frameworks, granting access to resources across different applications easily. However, vulnerabilities in OAuth implementations can create significant security risks. By implementing strong OAuth security controls, organizations can safeguard their users’ data, prevent unauthorized access to critical resources, and maintain user trust.

Salt Security’s recent investigation exposed several critical security flaws within the OAuth implementations of popular ChatGPT plug-ins. ChatGPT plugins enable ChatGPT to interact with the outside world and third-party websites like Google Drive, GitHub, Emails, and more. Beyond this most recent example of OAuth threats with ChatGPT, the Salt Labs team found several other OAuth-specific exploitable vulnerabilities within, Grammarly,, and Expo/CodeCademy, indicating the critical need for tools to help find and mitigate these types of risks before attackers can take advantage. These real-world examples underscore the importance of robust security measures to thwart sophisticated OAuth attack tactics before they can inflict significant damage.

With these new capabilities, the Salt platform will address:

Access Token and Authorization Code Theft: Vulnerabilities in OAuth systems can leave access tokens or authorization codes susceptible to theft. Attackers can leverage those stolen elements to impersonate legitimate users and gain unauthorized access to sensitive resources and applications.
Increasing OAuth Attacks: OAuth has been in widespread use for over a decade but we have seen attacks on the rise. This is caused by organizations’ increased usage of APIs and microservices making OAuth even more popular while increasing the complexity of securing it. Attackers have taken advantage of this by crafting specific OAuth-based attacks with continuing attempts to find additional OAuth vulnerabilities to exploit.

Salt Security’s OAuth Protection Package provides robust OAuth defenses that help organizations achieve several critical security objectives. With these enhancements, customer accounts, intellectual property and authorization tokens will be shielded from malicious actors who are tirelessly at work attempting to exploit vulnerabilities in OAuth implementations. In fact, within just five days of the OAuth protection package being deployed for Salt customers, it detected an OAuth vulnerability within a large financial institution. With the information on the detection, the customer was able to rapidly fix the vulnerability, preventing it from being exploited by threat actors.

Salt Security’s unwavering commitment to research and development ensures that its solutions remain effective against emerging OAuth attack techniques. Salt’s proactive approach keeps businesses a step ahead of evolving threats, allowing them to operate with greater confidence and agility.
