Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47849 in the wild and no public exploit code.\n\nAffected product: Spring Data REST. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-47849/ (Markdown: https://insights.sbomify.com/CVE-2026-47849/index.md)","id":"CVE-2026-47849","markdown":"https://insights.sbomify.com/CVE-2026-47849/index.md","name":"CVE-2026-47849","record":{"aliases":["CLSA-2026-1788196746","CLSA-2026-1788279532","CLSA-2026-1788357718","CLSA-2026-1788359035","GHSA-4xj4-jmcc-9rq7"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Spring Data REST library","requires_auth":"low_privilege","summary":"Attackers can modify protected identifier and version fields in Spring Data REST entities using JSON Patch requests, compromising data integrity.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_data_rest","vendor":"vmware"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-915","name":"Improperly Controlled Modification of Dynamically-Determined Object Attributes"}],"description":"Spring Data REST does not guard identifier (@Id) and version (@Version) properties against mutation via RFC 6902 JSON Patch (application/json-patch+json) requests.\nSpring Data REST 5.1.0\nSpring Data REST 5.0.0 - 5.0.6\nSpring Data REST 4.5.0 - 4.5.12\nSpring Data REST 4.0.0 - 4.4.15\nSpring Data REST 3.7.20 and earlier","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Spring Data REST allows mutation of identifier and version properties via JSON Patch","id":"CVE-2026-47849","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"business_logic","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Spring Data REST allows mutation of the version property of immutable aggregates via PUT","id":"CVE-2026-47850"},"packages":[],"prev":{"headline":"Reactor Netty WebSocket Client Leaks Credentials On Redirect","id":"CVE-2026-47848"},"products":["Spring Data REST"],"published":"2026-08-27","related":[{"cvss_score":8.1,"headline":"Spring Data REST SpEL Injection via Map Key in JSON Patch","id":"CVE-2026-41729","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":7.5,"headline":"Spring Data REST JSON Patch bypasses Jackson read-only property protection on nested objects and collections","id":"CVE-2026-41728","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":5.3,"headline":"Spring Data REST exposes persistence-layer internals in error responses","id":"CVE-2026-41730","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":5.3,"headline":"Spring Data REST Querydsl integration exposes Jackson-hidden persistent fields as filter keys","id":"CVE-2026-41837","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":5.3,"headline":"Exposure of Resource to Wrong Sphere in Spring Data REST","id":"CVE-2021-22047","kev_date_added":null,"published":"2021-10-28"},{"cvss_score":4.3,"headline":"Spring Data REST allows mutation of the version property of immutable aggregates via PUT","id":"CVE-2026-47850","kev_date_added":null,"published":"2026-08-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-27","vendors":["Spring"]},"summary":"Attackers can modify protected identifier and version fields in Spring Data REST entities using JSON Patch requests, compromising data integrity.","url":"https://insights.sbomify.com/CVE-2026-47849/"}
