Midday AI teamCache invalidation flaw: silent catch causes stale data and potential authz risk

Vulnerability Overview The page displays the source code of an open-source project named , which contains a Cache Inconsistency Vulnerability (Cache Invalidation Bug). Core Issue: In the operation of , the code employs a structure, and the block includes the following comment: This indicates that when the call fails, the exception is silently caught, and the cache is not invalidated immediately; instead, it relies on the natural expiration mechanism. This may result in inconsistency between the cache and the database state, causing users to see stale team data. --- Scope of Impact Affected Module: The -related logic in . Affected Scenarios: - When creating a team ( ), if cache invalidation fails, the newly created team information may not be immediately reflected in the cache. - When updating a team ( ), if cache invalidation fails, the modified team information may take time to take effect. - When deleting a team ( ), if cache invalidation fails, the deleted team may still appear in the cache. Potential Consequences: - The user interface displays stale data (e.g., deleted teams remain visible). - Permission checks may rely on stale cache entries, leading to privilege escalation or insufficient permissions. - Data consistency is compromised, affecting both user experience and system reliability. --- Remediation 1. Enhance Error Handling: Log an event or throw a non-fatal error within the block to facilitate monitoring and debugging. 2. Enforce Cache Invalidation: Ensure the call succeeds, or implement a retry mechanism. 3. Reduce Cache TTL: As a temporary mitigation, shorten the cache expiration time to minimize the window of inconsistency. 4. Add Unit Tests: Simulate cache invalidation failure scenarios to verify that system behavior aligns with expectations. --- POC / Exploitation Code The page does not provide standalone POC code, but the key code snippet is as follows: This code indicates that the developer recognized cache invalidation might fail and opted for "non-fatal" handling, but this design poses risks in scenarios requiring strong consistency.
