Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-27480 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-xar-model (Maven): affected from 1.1-milestone-3; fixed in 13.10.11\n- org.xwiki.platform:xwiki-platform-xar-model (Maven): affected from 1.1-milestone-3; fixed in 13.10.11\n- org.xwiki.platform:xwiki-platform-xar-model (Maven): affected from 14.0; fixed in 14.4.7\n- org.xwiki.platform:xwiki-platform-xar-model (Maven): affected from 14.0; fixed in 14.4.7\n- org.xwiki.platform:xwiki-platform-xar-model (Maven): affected from 14.5; fixed in 14.10-rc-1\n- org.xwiki.platform:xwiki-platform-xar-model (Maven): affected from 14.5; fixed in 14.10-rc-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-2023-27480/ (Markdown: https://insights.sbomify.com/CVE-2023-27480/index.md)","id":"CVE-2023-27480","markdown":"https://insights.sbomify.com/CVE-2023-27480/index.md","name":"CVE-2023-27480","record":{"aliases":["GHSA-gx4f-976g-7g6v"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki Platform","requires_auth":"low_privilege","summary":"An attacker with edit rights can exploit an XXE vulnerability in XAR imports to read arbitrary files from the server.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it.
