An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-18111 in the wild and no public exploit code.\n\nAffected product: Atlassian Application Links. 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-2017-18111/ (Markdown: https://insights.sbomify.com/CVE-2017-18111/index.md)","id":"CVE-2017-18111","markdown":"https://insights.sbomify.com/CVE-2017-18111/index.md","name":"CVE-2017-18111","record":{"aliases":["GHSA-9563-9277-f9w9"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Atlassian Application Links","requires_auth":"high_privilege","summary":"An XXE vulnerability in Atlassian Application Links allows attackers to read internal files, probe network resources, and cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"application_links","vendor":"atlassian"}],"cvss":{"score":8.7,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"The OAuthHelper in Atlassian Application Links before version 5.0.10, from version 5.1.0 before version 5.1.3, and from version 5.2.0 before version 5.2.6 used an XML document builder that was vulnerable to XXE when consuming a client OAuth request.
