CVE-2025-30188
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMalicious or unintentional API requests can be used to add significant amount of data to caches. Caches may evict information that is required to operate the web frontend, which leads to unavailability of the component. Please deploy the provided updates and patch releases. No publicly available exploits are known
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a cache-based denial of service vulnerability where malicious or unintentional API requests can flood caches with data, causing eviction of critical information needed for the web frontend to operate. The attack exploits insufficient cache size limits or improper cache key management, leading to component unavailability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm caching is enabledReview your application or web server configuration files to determine if any caching mechanism (HTTP caching, API response caching, application-level caching) is activeAffected if Caching is enabled and no proper cache size limits are configured
-
Check cache size limit configurationInspect the cache configuration settings for any maximum size, quota, or eviction policy settings. Look for parameters controlling cache memory usage or item countsAffected if Cache size limits are absent, set too high, or not enforced
-
Review cache key isolationExamine how cache keys are generated for different request types (e.g., API endpoints, frontend assets, user sessions). Check if different request types share the same cache namespace without proper separationAffected if Cache keys do not isolate frontend critical data from high-volume API requests
-
Inspect cache eviction behaviorMonitor cache logs or metrics for eviction patterns, particularly if frontend assets or critical data are being evicted frequently while API response caching is activeAffected if Cache evictions are occurring on critical frontend components due to API request volume
-
Check API endpoint caching policyReview API endpoint configuration to identify which endpoints have caching enabled and what their cache TTL (time-to-live) or storage footprint might beAffected if API endpoints are cached with long TTLs or large response sizes without throttling
You are affected if your environment has caching enabled without proper cache size limits or cache key isolation, allowing API requests to evict critical frontend data from the cache.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataDeploy the provided patch releases and updates. Additionally, implement proper cache size limits, rate limiting on API endpoints, and cache key isolation to prevent one request type from evicting critical frontend data.
