An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-40758 in the wild and no public exploit code.\n\nAffected product: Siemens Mendix SAML (Mendix 10.12 compatible). 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-2025-40758/ (Markdown: https://insights.sbomify.com/CVE-2025-40758/index.md)","id":"CVE-2025-40758","markdown":"https://insights.sbomify.com/CVE-2025-40758/index.md","name":"CVE-2025-40758","record":{"aliases":["GHSA-jcx5-8f6x-5fx8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Mendix SAML library","requires_auth":"none","summary":"Insufficient SAML signature validation allows unauthenticated attackers to hijack accounts in specific SSO configurations.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"A vulnerability has been identified in Mendix SAML (Mendix 10.12 compatible) (All versions \u003c V4.0.3), Mendix SAML (Mendix 10.21 compatible) (All versions \u003c V4.1.2), Mendix SAML (Mendix 9.24 compatible) (All versions \u003c V3.6.21).
