Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-41862 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.springframework.statemachine:spring-statemachine-kryo (Maven): affected from 3.2.0 up to 3.2.4; no fix listed\n- org.springframework.statemachine:spring-statemachine-kryo (Maven): affected from 3.2.0 up to 3.2.4; no fix listed\n- org.springframework.statemachine:spring-statemachine-kryo (Maven): affected from 4.0.0; fixed in 4.0.2\n- org.springframework.statemachine:spring-statemachine-kryo (Maven): affected from 4.0.0; fixed in 4.0.2\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-2026-41862/ (Markdown: https://insights.sbomify.com/CVE-2026-41862/index.md)","id":"CVE-2026-41862","markdown":"https://insights.sbomify.com/CVE-2026-41862/index.md","name":"CVE-2026-41862","record":{"aliases":["GHSA-85qj-f5wg-rwp9"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Java state machine library","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution by exploiting unsafe Kryo deserialization in Spring Statemachine persistence backends.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_statemachine","vendor":"broadcom"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Spring Statemachine's Kryo-based persistence backends (JPA, MongoDB, Redis and ZooKeeper) deserialise persisted state-machine contexts without enforcing a class allowlist (CWE-502, deserialisation of untrusted data), which can lead to remote code execution inside the application JVM.\n\nAffected versions:\nSpring Statemachine 4.0.0 through 4.0.1\nSpring Statemachine 3.2.0 through 3.2.4","ecosystems":["Maven"],"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 Statemachine's Kryo-based persistence backends deserialize persisted state-machine contexts without enforcing a class allowlist","id":"CVE-2026-41862","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":4,"n_references":1,"next":{"headline":"Spring AI's support for Anthropic's Skills API used LLM-influenced filenames unsanitized in Path.resolve before writing files to disk","id":"CVE-2026-41863"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["3.2.0"],"last_affected":["3.2.4"],"package":"org.springframework.statemachine:spring-statemachine-kryo","purl":null,"source":"GHSA-85qj-f5wg-rwp9"},{"ecosystem":"Maven","fixed":[],"introduced":["3.2.0"],"last_affected":["3.2.4"],"package":"org.springframework.statemachine:spring-statemachine-kryo","purl":"pkg:maven/org.springframework.statemachine/spring-statemachine-kryo","source":"GHSA-85qj-f5wg-rwp9"},{"ecosystem":"Maven","fixed":["4.0.2"],"introduced":["4.0.0"],"last_affected":[],"package":"org.springframework.statemachine:spring-statemachine-kryo","purl":null,"source":"GHSA-85qj-f5wg-rwp9"},{"ecosystem":"Maven","fixed":["4.0.2"],"introduced":["4.0.0"],"last_affected":[],"package":"org.springframework.statemachine:spring-statemachine-kryo","purl":"pkg:maven/org.springframework.statemachine/spring-statemachine-kryo","source":"GHSA-85qj-f5wg-rwp9"}],"prev":{"headline":"Arbitrary Root File Write via Path Traversal in BOSH agent","id":"CVE-2026-41861"},"products":["Spring Statemachine"],"published":"2026-06-23","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"total"},"state":"PUBLISHED","updated":"2026-06-24","vendors":["Spring"]},"summary":"Attackers can achieve remote code execution by exploiting unsafe Kryo deserialization in Spring Statemachine persistence backends.","url":"https://insights.sbomify.com/CVE-2026-41862/"}
