Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H
Unauthenticated network input drives the flaw (PR:N/AV:N), but it requires a non-default SimpleEvaluationContext-plus-compiler configuration (AC:H); a guard bypass enabling method invocation is rated C:H/I:H/A:H.
Primary rating from Vendor (vmware).

Lifecycle Timeline
4DescriptionCVE.org
Applications that evaluate Spring Expression Language (SpEL) expressions using SimpleEvaluationContext may be vulnerable to a safety guard bypass when the SpEL expression compiler is active. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.25.RELEASE and earlier
AnalysisAI
Safety-guard bypass in the Spring Framework SpEL engine (VMware/Broadcom) lets attacker-controlled expression input escape the restricted SimpleEvaluationContext sandbox when the SpEL bytecode compiler is active, affecting Spring Framework 5.2.x through 7.0.8 across the 5.3, 6.0, 6.1, 6.2 and 7.0 lines. Because SimpleEvaluationContext is the API applications are told to use to safely evaluate untrusted expressions, this bypass can escalate a data-binding-only context into broader method invocation with high integrity and availability impact (CVSS 9.1, CWE-913). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a specific application-side pattern: the target application must (1) evaluate attacker-influenced input as a SpEL expression, (2) do so via SimpleEvaluationContext, and (3) have the SpEL expression compiler active (SpelCompilerMode set to IMMEDIATE or MIXED rather than the default OFF/interpreted). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed and warrant nuance. … 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 | Patch available per vendor advisory (https://spring.io/security/cve-2026-59283) - upgrade to the fixed maintenance release of your Spring Framework line (the release immediately following each affected range on the 7.0, 6.2, 6.1, 6.0, 5.3 and 5.2 branches); confirm the exact fixed version numbers directly from the spring.io advisory rather than assuming them, as open-source fixes are published for supported lines while 6.0.x/5.3.x/5.2.x fixes may require a commercial/Enterprise support subscription. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct an inventory of all applications and services using Spring Framework versions 5.2.x through 7.0.8 (specifically 5.3, 6.0, 6.1, 6.2, and 7.0 release lines) and determine which enable SpEL expression evaluation on untrusted input. …
