It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-40993 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.springframework.security:spring-security-saml2-service-provider (Maven): affected from 7.0.0; fixed in 7.0.6\n- org.springframework.security:spring-security-saml2-service-provider (Maven): affected from 7.0.0; fixed in 7.0.6\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-2026-40993/ (Markdown: https://insights.sbomify.com/CVE-2026-40993/index.md)","id":"CVE-2026-40993","markdown":"https://insights.sbomify.com/CVE-2026-40993/index.md","name":"CVE-2026-40993","record":{"aliases":["GHSA-2q7c-5gjm-7q23","MINI-rcq2-xvj3-vgvp","ROOT-APP-MAVEN-CVE-2026-40993"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Spring Security library","requires_auth":"high_privilege","summary":"An attacker with database write access can inject malicious serialized payloads into SAML credential columns, leading to remote code execution.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_security","vendor":"vmware"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:H/UI:N/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"An attacker with write permissions to the database table managed by JdbcAssertingPartyMetadataRepository (saml2_asserting_party_metadata) may be able to store malicious serialized payloads in the columns containing the collection of verification or encryption credentials (verification_credentials and encryption_credentials, respectively).\n\nAffected versions:\nSpring Security 7.0.0 through 7.0.5.","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":"Unfiltered Java Native Deserialization of SAML 2.0 Asserting Party Credentials BLOB Database Entry","id":"CVE-2026-40993","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Wss4jSecurityInterceptor disables WS-I BSP validation by default","id":"CVE-2026-40994"},"packages":[{"ecosystem":"Maven","fixed":["7.0.6"],"introduced":["7.0.0"],"last_affected":[],"package":"org.springframework.security:spring-security-saml2-service-provider","purl":null,"source":"GHSA-2q7c-5gjm-7q23"},{"ecosystem":"Maven","fixed":["7.0.6"],"introduced":["7.0.0"],"last_affected":[],"package":"org.springframework.security:spring-security-saml2-service-provider","purl":"pkg:maven/org.springframework.security/spring-security-saml2-service-provider","source":"GHSA-2q7c-5gjm-7q23"}],"prev":{"headline":"Mail Auto-Configuration Does Not Enable SSL Hostname Verification","id":"CVE-2026-40992"},"products":["Spring Security"],"published":"2026-06-09","related":[{"cvss_score":9.8,"headline":"Authorization Bypass in Spring Security","id":"CVE-2014-3527","kev_date_added":null,"published":"2017-05-25"},{"cvss_score":9.6,"headline":"Spring Security OAuth2 Authorization Server: Insufficient validation of Dynamic Client Registration metadata","id":"CVE-2026-59354","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":9.4,"headline":"Spring Security embedded UnboundID LDAP server exposes well-known administrative bind DN on all network interfaces","id":"CVE-2026-59270","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":9.1,"headline":"Under Some Conditions Spring Security HTTP Headers Are not Written","id":"CVE-2026-22732","kev_date_added":null,"published":"2026-03-19"},{"cvss_score":9.1,"headline":"Access Control Bypass in Spring Security","id":"CVE-2023-34034","kev_date_added":null,"published":"2023-07-19"},{"cvss_score":8.2,"headline":"Spring Security Authorization Server Default Consent Page is vulnerable to Cross-Site Scripting (XSS)","id":"CVE-2026-47877","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":8.1,"headline":"Deserialization of Untrusted Data in Spring Security","id":"CVE-2017-4995","kev_date_added":null,"published":"2017-11-27"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-06-27","vendors":["Spring"]},"summary":"An attacker with database write access can inject malicious serialized payloads into SAML credential columns, leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2026-40993/"}
