📌 OAuth Vulnerabilities Summary
OAuth vulnerabilities are security weaknesses that can occur in applications or systems using the OAuth protocol for authorising user access. These flaws might let attackers bypass permissions, steal access tokens, or impersonate users. Common vulnerabilities include improper redirect URI validation, weak token storage, and insufficient user consent checks.
🙋🏻♂️ Explain OAuth Vulnerabilities Simply
Imagine giving a friend a spare key to your house so they can water your plants, but you do not check if it is really your friend asking. If someone else tricks you and gets the key, they can enter your house without your permission. OAuth vulnerabilities are like leaving your digital keys unprotected, making it easy for someone to sneak in where they should not.
📅 How Can it be used?
Identify and mitigate OAuth vulnerabilities to ensure only authorised users can access sensitive project resources.
🗺️ Real World Examples
A mobile banking app lets users log in with a social media account using OAuth. If the app does not properly validate redirect URIs, an attacker could intercept the login process and steal access tokens, gaining unauthorised access to the user’s banking information.
A cloud storage service allows third-party apps to connect using OAuth. If these apps store access tokens insecurely, a hacker who compromises the app could use the tokens to access all files in the user’s storage account without needing their password.
✅ FAQ
What are some common ways attackers can exploit OAuth vulnerabilities?
Attackers can take advantage of OAuth vulnerabilities by tricking users into granting access to malicious apps, stealing access tokens to impersonate someone else, or bypassing security checks if redirect links are not properly validated. These weaknesses can give attackers access to personal data or allow them to perform actions as if they were the real user.
How can I tell if an app is handling OAuth securely?
A trustworthy app will only ask for the permissions it genuinely needs, show clear consent screens, and use secure methods to handle your login details. If an app redirects you to strange websites or asks for more access than seems necessary, it might not be handling OAuth safely.
What can developers do to reduce the risk of OAuth vulnerabilities?
Developers should always check that redirect links are valid, store tokens securely, and make sure users clearly understand what permissions they are granting. Regular security reviews and keeping up with best practices can help keep OAuth-based systems safer for everyone.

Cloud Workload Migration
Cloud workload migration is the process of moving applications, data, and related services from on-premises computers or other clouds to a cloud computing environment. This migration can involve shifting entire systems or just specific components, depending on business needs and goals. The aim is often to improve flexibility, reduce costs, and take advantage of the cloud's scalability and remote access.
Self-Service Portal
A self-service portal is an online platform that allows users to access information, manage their accounts, and solve common issues on their own without needing to contact support staff. These portals often provide features like viewing or updating personal details, submitting requests, tracking orders, or accessing help articles. The main goal is to give users control and save time for both the user and the organisation.
Quantum Algorithm Analysis
Quantum algorithm analysis is the process of examining and understanding how algorithms designed for quantum computers work, how efficient they are, and what problems they can solve. It involves comparing quantum algorithms to classical ones to see if they offer speed or resource advantages. This analysis helps researchers identify which tasks can benefit from quantum computing and guides the development of new algorithms.
Query Generalisation
Query generalisation is the process of making a search or database query broader so that it matches a wider range of results. This is done by removing specific details, using more general terms, or relaxing conditions in the query. The goal is to retrieve more relevant data, especially when the original query returns too few results.
Address Space Layout Randomization (ASLR)
Address Space Layout Randomisation (ASLR) is a security technique used by operating systems to randomly arrange the memory addresses used by system and application processes. By shuffling the locations of key data areas, such as the stack, heap, and libraries, ASLR makes it harder for hackers to predict where specific code or data is stored. This unpredictability helps prevent certain types of attacks, such as buffer overflows, from succeeding.
