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-2026-40975 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.springframework.boot:spring-boot-cassandra (Maven): affected all versions up to 2.7.32; no fix listed\n- org.springframework.boot:spring-boot-cassandra (Maven): affected all versions up to 2.7.32; no fix listed\n- org.springframework.boot:spring-boot-cassandra (Maven): affected from 3.3.0 up to 3.3.18; no fix listed\n- org.springframework.boot:spring-boot-cassandra (Maven): affected from 3.3.0 up to 3.3.18; no fix listed\n- org.springframework.boot:spring-boot-cassandra (Maven): affected from 3.4.0 up to 3.4.15; no fix listed\n- org.springframework.boot:spring-boot-cassandra (Maven): affected from 3.4.0 up to 3.4.15; no fix listed\n- org.springframework.boot:spring-boot-cassandra (Maven): affected from 3.5.0; fixed in 3.5.14\n- org.springframework.boot:spring-boot-cassandra (Maven): affected from 3.5.0; fixed in 3.5.14\n- org.springframework.boot:spring-boot-cassandra (Maven): affected from 4.0.0; fixed in 4.0.6\n- org.springframework.boot:spring-boot-cassandra (Maven): affected from 4.0.0; fixed in 4.0.6\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-2026-40975/ (Markdown: https://insights.sbomify.com/CVE-2026-40975/index.md)","id":"CVE-2026-40975","markdown":"https://insights.sbomify.com/CVE-2026-40975/index.md","name":"CVE-2026-40975","record":{"aliases":["GHSA-m4x9-hx6x-2c43"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Spring Boot framework","requires_auth":"none","summary":"Developers using Spring Boot random value properties for secrets risk exposure due to predictable PRNG output, requiring upgrades to secure versions.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_boot","vendor":"vmware"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"},{"id":"CWE-330","name":"Use of Insufficiently Random Values"}],"description":"Values produced by ${random.value} are not suitable for use as secrets. ${random.uuid} is not affected. ${random.int} and ${random.long} should never be used for secrets as they are numeric values with a predictable range.\n\nAffected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); random value property source / weak PRNG for secrets.
