🔒 A high-severity authentication flaw in Azure SRE Agent exposed agent activity streams to unauthorized tenants, researcher Yanir Tsarimi of Enclave AI reported. Tracked as CVE-2026-32173 with a CVSS score of 8.6, the vulnerability stemmed from an Entra ID app registration configured as multi-tenant and a WebSocket hub that accepted tokens without tenant authorization checks. The hub broadcast agent prompts, internal reasoning, commands and outputs to all connected clients. Microsoft applied a server-side fix and says no customer action is required, but organizations that ran the agent during preview should review any credentials or sensitive data that may have traversed agent interactions.

🔍 A Taboola tracking pixel approved by a bank silently redirected authenticated users to a Temu tracking endpoint without the bank's knowledge, user consent, or any security control flagging a violation. Reflectiz discovered the chain during a February 2026 audit: an initial GET to sync.taboola.com returned a 302 to a temu.com pixel and included Access-Control-Allow-Credentials: true, enabling credentialed cross-origin requests. Conventional tools missed the behavior because they validate the declared script origin rather than runtime redirect destinations. Organizations should inspect browser runtime behavior, tighten CSPs, and consider sandboxing third-party scripts on authenticated pages.

🔍 LinkedIn was found to inject hidden JavaScript that fingerprints visitors' browsers, testing for over 6,000 Chrome extensions and collecting device and system details such as CPU cores, memory, screen resolution, timezone, battery status, audio information, and storage features. Researchers say the script links extension presence to identifiable profiles; LinkedIn confirms extension detection but insists it is used to stop scraping and protect platform stability. BleepingComputer observed a randomized script file performing the checks but could not verify claims about downstream sharing or commercial use.

🔍 A new report named BrowserGate alleges that LinkedIn injects hidden JavaScript into user sessions to probe browsers for installed extensions and collect device characteristics. BleepingComputer independently observed a randomized script that attempted to detect 6,236 extensions by checking extension resource URLs and also harvested CPU, memory, screen, timezone, battery, audio, and storage details. LinkedIn says it looks for extensions that scrape content or violate its Terms and uses detection to inform defenses and enforcement, while the report warns this scanning could map competitors' customers and enable profiling. The use and sharing of the collected data have not been independently verified.

🔒 Unit 42 disclosed a permissions flaw in Vertex AI where the default Per-Project, Per-Product Service Agent (P4SA) can expose credentials and OAuth scopes via the metadata service. Researchers showed attackers could use those credentials to pivot into customer projects, read Google Cloud Storage buckets, and download images from restricted Artifact Registry repositories. Google updated docs and advises using BYOSA and least-privilege scopes; organizations should validate agent permissions before deployment.

⚠️ A software defect introduced during a routine overnight update on 12 March at Lloyds Banking Group briefly exposed transactions and account information belonging to as many as 447,936 customers across Lloyds, Halifax and Bank of Scotland mobile apps. Approximately 114,182 users clicked transactions that displayed other customers' details, which could include payment references and national insurance numbers. The bank reported the issue to regulators within required timeframes, paid £139,000 to 3,625 customers in compensation, and said it found no evidence of financial loss or fraud.
