CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:LSummary
CVE-2026-22741 is a low-severity Use of Cache Containing Sensitive Information (CWE-524) vulnerability in Vmware Spring Framework. Its CVSS base score is 3.1 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 15th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

Vulnerability Data
Spring MVC and WebFlux applications are vulnerable to cache poisoning when resolving static resources. More precisely, an application can be vulnerable when all the following are true: * the application is using Spring MVC or Spring WebFlux * the application…

is configuring the resource chain support https://docs.spring.io/spring-framework/reference/web/webmvc/mvc-config/static-resources.html#page-title with caching enabled * the application adds support for encoded resources resolution * the resource cache must be empty when the attacker has access to the application When all the conditions above are met, the attacker can send malicious requests and poison the resource cache with resources using the wrong encoding. This can cause a denial of service by breaking the front-end application for clients.

Mitigating Controls (NIST 800-53 r5) AI
Enforces access authorizations so that cached sensitive data cannot be read by actors outside the intended sphere.
Directly prevents unauthorized transfer of information through shared resources such as caches.
Controls information flows to keep sensitive data from leaving its authorized control sphere via caches.
Requires cryptographic or other protection of sensitive information at rest, which covers cached data.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Protecting confidentiality of data-at-rest covers caches that persist sensitive information.
Enforcing least-privilege access permissions directly limits who can read cached sensitive data.
Protecting data-in-use can mitigate exposure when caches hold transient sensitive values.
Logical access controls on environments reduce the chance an outsider can reach the cache.
Hardened configuration baselines can disable or secure caching of sensitive data.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Data leakage prevention can block unauthorized access to cached sensitive information.
Information access restriction directly limits who can read cached sensitive data.
Information deletion ensures sensitive data is removed from caches when no longer needed.
Cryptography can protect cached data at rest, but does not address access control scope.
Secure coding practices prevent caching of sensitive data outside intended boundaries.
Environment separation reduces risk of cache exposure across development/test/production.
