AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N
Network PATCH endpoint requires authenticated session (PR:L); integrity is high due to @Id/@Version field mutation; no availability impact applies.

2DescriptionCVE.org
Spring Data REST does not guard identifier (@Id) and version (@Version) properties against mutation via RFC 6902 JSON Patch (application/json-patch+json) requests. Spring Data REST 5.1.0 Spring Data REST 5.0.0 - 5.0.6 Spring Data REST 4.5.0 - 4.5.12 Spring Data REST 4.0.0 - 4.4.15 Spring Data REST 3.7.20 and earlier
AnalysisAI
Spring Data REST fails to protect entity identifier (@Id) and optimistic-locking version (@Version) fields from mutation through RFC 6902 JSON Patch (application/json-patch+json) PATCH requests, allowing authenticated low-privilege network attackers to overwrite primary keys and version counters on exposed JPA entities. Affected versions span the full 3.x lineage through 5.1.0, representing a broad swath of the Spring ecosystem. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires all of the following: the target application uses Spring Data REST (not a custom Spring MVC controller) and exposes HTTP PATCH endpoints; those endpoints accept the application/json-patch+json Content-Type (RFC 6902 mode, not RFC 7396 JSON Merge Patch); the attacker holds a valid authenticated session with at least low-privilege access (PR:L per vendor CVSS); and the targeted entities have @Id or @Version annotated fields, which is standard for all JPA entities. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-supplied CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N, score 7.1) indicates a network-reachable, low-complexity attack requiring only low-privilege authentication with no user interaction, yielding high integrity impact and low confidentiality impact. … 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 | Consult the Spring security advisory at https://spring.io/security/cve-2026-47849 for confirmed patched releases; based on the stated affected ranges, fixed versions are expected at 5.0.7+, 4.5.13+, 4.4.16+, and a post-5.1.0 release, but these numbers are inferred from the affected-version boundaries and not independently verified from the advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct an inventory of all applications running Spring Data REST versions 3.x through 5.1.0, identify which REST endpoints expose JPA entities to low-privilege users, and document the sensitivity and scope of exposed data. …
