Organization Cache

What Organization Cache Means in a Salesforce Org

An organization cache is shared across the whole Salesforce org, so it behaves like common application state rather than private user data. That matters because any value placed there can be read by other transactions and users if the application logic exposes it, so developers should treat cached content as org-wide material, not session-bound storage.

In practice, the term describes a performance feature with security implications. Caching reduces repeated computation and data access, but it also changes the trust model: once data is stored in a shared cache, the application must assume that the cached copy may outlive the request that created it and may be reused in a different execution context.

Why Shared Cache Changes the Security Model

Shared caching introduces a classic boundary problem, because data that was safe in one context can become unsafe when reused elsewhere. If the application caches sensitive attributes, permission-dependent results, or tenant-specific values without careful scoping, it can leak information across users, flows, or business processes.

This is especially important when the cached value was derived from access-controlled records or from a user-specific decision. The cache itself is not the issue, but the assumption that cached output is still valid after the surrounding context has changed often creates the weakness.

Common Failure Modes and Misuse Patterns

The most common problems are stale data, over-broad reuse, and accidental disclosure through shared state. A cache entry may survive longer than the data it represents, or it may be populated from a request that had stronger access than the next request that reads it.

• Storing user-specific results in a cache that is effectively org-wide.
• Caching secrets, tokens, or other sensitive values that should not be broadly reusable.
• Reusing cached authorization decisions after the underlying permission set has changed.
• Assuming cache contents are safe because they are “temporary” rather than durable.

How to Use Organization Cache Safely

Safe use starts with data classification: cache only values that can tolerate reuse across requests and do not depend on a single user’s security context. If a value is permission-sensitive, build the cache key and cache lifetime around the access model so that a later consumer cannot receive an unintended result.

It is also important to keep the cache’s purpose narrow. Use it for reusable application data, not as a general store for session data, credentials, or business decisions that must be recomputed under the current user context. When in doubt, prefer recomputation over unsafe reuse.

Operationally, teams should review what is being cached, who can influence cache population, and whether invalidation happens when data or permissions change. The right mental model is that cache performance gains are only safe when the application can prove the cached object is still appropriate for the current request.

Risk and Threat Considerations

Shared org-wide caching can turn a performance optimization into an exposure path if sensitive or permission-dependent values are cached too broadly. The main risk is not the cache mechanism itself, but the possibility that one user, flow, or integration can receive data that was computed under a different trust context.

Failure mechanism: An application stores data in shared cache without sufficient scoping, then later reuses that value after the original authorization context, user context, or data state has changed.

Impact: The result can be stale output, cross-user disclosure, incorrect business decisions, or unintended exposure of sensitive application data.

Practitioner Guidance

Why practitioners should care: The key judgement is whether the cached value is safe to reuse outside the request that created it. If the answer depends on user identity, permissions, or rapidly changing business state, the cache design needs stricter scoping or a different approach.

What to watch for: Review any code path that caches access-controlled results, per-user calculations, or values that might reveal more than intended when reused. Shared cache is best treated as a shared performance layer, not as private storage.
