An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-40991 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.springframework.restdocs:spring-restdocs-restassured (Maven): affected all versions up to 2.0.8.RELEASE; no fix listed\n- org.springframework.restdocs:spring-restdocs-restassured (Maven): affected all versions up to 2.0.8.RELEASE; no fix listed\n- org.springframework.restdocs:spring-restdocs-restassured (Maven): affected from 3.0.0; fixed in 3.0.6\n- org.springframework.restdocs:spring-restdocs-restassured (Maven): affected from 3.0.0; fixed in 3.0.6\n- org.springframework.restdocs:spring-restdocs-restassured (Maven): affected from 4.0.0; fixed in 4.0.1\n- org.springframework.restdocs:spring-restdocs-restassured (Maven): affected from 4.0.0; fixed in 4.0.1\n- org.springframework.restdocs:spring-restdocs-webtestclient (Maven): affected all versions up to 2.0.8.RELEASE; no fix listed\n- org.springframework.restdocs:spring-restdocs-webtestclient (Maven): affected all versions up to 2.0.8.RELEASE; no fix listed\n- org.springframework.restdocs:spring-restdocs-webtestclient (Maven): affected from 3.0.0; fixed in 3.0.6\n- org.springframework.restdocs:spring-restdocs-webtestclient (Maven): affected from 3.0.0; fixed in 3.0.6\n- org.springframework.restdocs:spring-restdocs-webtestclient (Maven): affected from 4.0.0; fixed in 4.0.1\n- org.springframework.restdocs:spring-restdocs-webtestclient (Maven): affected from 4.0.0; fixed in 4.0.1\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-2026-40991/ (Markdown: https://insights.sbomify.com/CVE-2026-40991/index.md)","id":"CVE-2026-40991","markdown":"https://insights.sbomify.com/CVE-2026-40991/index.md","name":"CVE-2026-40991","record":{"aliases":["CLSA-2026-1793192311","GHSA-6rpq-6vv2-5222","ROOT-APP-MAVEN-CVE-2026-40991"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Spring REST Docs","requires_auth":"none","summary":"Attackers can exploit XXE injection in Spring REST Docs when documenting malicious remote APIs, potentially exposing sensitive data or causing denial of service.","user_interaction":"required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_rest_docs","vendor":"broadcom"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"When using spring-restdocs-webtestclient or spring-restdocs-restassured to document a remote API accessed over HTTP, an attacker who compromises the API or tricks the user into documenting a malicious API can perform an XXE injection attack when the documentation-generating tests are next executed.\n\nAffected versions:\nSpring REST Docs 4.0.0;
