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-2026-41849 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.springframework:spring-expression (Maven): affected all versions up to 5.3.39; no fix listed\n- org.springframework:spring-expression (Maven): affected all versions up to 5.3.39; no fix listed\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-2026-41849/ (Markdown: https://insights.sbomify.com/CVE-2026-41849/index.md)","id":"CVE-2026-41849","markdown":"https://insights.sbomify.com/CVE-2026-41849/index.md","name":"CVE-2026-41849","record":{"aliases":["CLEANSTART-2026-KM08371","CLSA-2026-1783558960","CLSA-2026-1783645376","CLSA-2026-1783645393","CLSA-2026-1787846138","DEBIAN-CVE-2026-41849","GHSA-775g-4xr8-78h8","ROOT-APP-MAVEN-CVE-2026-41849","UBUNTU-CVE-2026-41849"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java application framework","requires_auth":"none","summary":"An attacker can cause a Denial of Service in Spring Framework by submitting a crafted SpEL expression that triggers an integer overflow and excessive resource consumption.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_framework","vendor":"vmware"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An integer overflow vulnerability exists in the evaluation logic of the Spring Expression Language (SpEL).
