CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:NSummary
CVE-2026-22732 is a critical-severity Forced Browsing (CWE-425) vulnerability in Vmware Spring Security. Its CVSS base score is 9.1 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 39th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-24 (Access Control Decisions) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-22732 affects Spring Security Servlet applications that use the default lazy writing of HTTP headers, where applications specify HTTP response headers but they may not be written. This vulnerability impacts versions from 5.7.0 through 5.7.21, 5.8.0 through 5.8.23, 6.3.0 through 6.3.14, 6.4.0 through 6.4.14, 6.5.0 through 6.5.8, and 7.0.0 through 7.0.3. It is associated with CWE-425 and carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).
Unauthenticated attackers can exploit this vulnerability remotely over the network with low attack complexity and no user interaction required. Exploitation prevents the intended HTTP response headers from being applied, resulting in high confidentiality and integrity impacts but no availability impact.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly requires enforcement of authorizations for access to resources such as URLs, scripts, and files, structurally preventing forced browsing.
AC-24 requires that access-control decisions be applied to every request, addressing the missing enforcement on restricted URLs.
AC-6 requires restricting authorizations to the minimum needed, reducing the set of resources that must be protected against direct requests.

Security testing can detect forced-browsing flaws, but the control itself does not prevent them in production.
Information access restriction implements the technical enforcement that directly blocks unauthorized direct requests.
Access control policy directly requires authorization checks on all resources, preventing forced browsing.
Managing access rights ensures every URL/script/file is explicitly authorized, mitigating direct request attacks.
Privileged access rights control enforces least-privilege checks on restricted endpoints.
Secure SDLC can include authorization design, yet the control itself does not guarantee runtime enforcement.
