Severity by source
AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:N
Sending an HTTP request to a serverless endpoint needs no authentication (PR:N, UI:N); AC:H reflects the precondition that application logic must rely on isSecure() for security decisions.
Primary rating from Vendor (vmware).

Implementation of isSecure() call of ServerlessHttpServletRequest does not verify the actual scheme. Spring Cloud Function 5.0.0 - 5.0.3 Spring Cloud Function 4.3.0 - 4.3.4 Spring Cloud Function 4.2.0 - 4.2.7
AnalysisAI
Spring Cloud Function's ServerlessHttpServletRequest.isSecure() method returns an unchecked result that does not reflect the actual HTTP transport scheme, enabling applications that gate security decisions on this call to behave incorrectly. Affected versions span three active release lines: 5.0.0-5.0.3, 4.3.0-4.3.4, and 4.2.0-4.2.7. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the following specific conditions to all be present simultaneously: the target must be running a Spring Cloud Function serverless deployment on one of the affected version lines (5.0.0-5.0.3, 4.3.0-4.3.4, 4.2.0-4.2.7); the application code must explicitly call isSecure() on the ServerlessHttpServletRequest object to gate a security-relevant decision; and per the vendor CVSS vector (PR:H, UI:R, AC:H), the attacker must hold high-privilege access and trigger user interaction under high-complexity conditions. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS vector AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:N yields a score of 3.1 (Low), and all individual metrics reinforce a low-priority assessment. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary remediation is to upgrade to a patched release of Spring Cloud Function per the vendor advisory at https://spring.io/security/cve-2026-59297; exact fixed versions (expected to be 5.0.4+, 4.3.5+, and 4.2.8+ for the respective lines) are not confirmed from available input data and must be verified against the advisory directly - do not infer version numbers from this analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
