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-2026-40977 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-2026-40977/ (Markdown: https://insights.sbomify.com/CVE-2026-40977/index.md)","id":"CVE-2026-40977","markdown":"https://insights.sbomify.com/CVE-2026-40977/index.md","name":"CVE-2026-40977","record":{"aliases":["GHSA-5368-6h4h-gr29"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Spring Boot library","requires_auth":"high_privilege","summary":"A local attacker can corrupt a file on the host via symlink attacks when ApplicationPidFileWriter is enabled.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_boot","vendor":"vmware"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"When an application is configured to use `ApplicationPidFileWriter`, a local attacker with write access to the PID file's location can corrupt one file on the host each time the application is started.\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); PID file / symlink behavior (`ApplicationPidFileWriter`).
