Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-29516 exists.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-attachment-ui (Maven): affected from 14.0-rc-1; fixed in 14.4.8\n- org.xwiki.platform:xwiki-platform-attachment-ui (Maven): affected from 14.0-rc-1; fixed in 14.4.8\n- org.xwiki.platform:xwiki-platform-attachment-ui (Maven): affected from 14.5; fixed in 14.10.1\n- org.xwiki.platform:xwiki-platform-attachment-ui (Maven): affected from 14.5; fixed in 14.10.1\n- org.xwiki.platform:xwiki-platform-attachment-ui (Maven): affected from 2.0-rc-2; fixed in 13.10.11\n- org.xwiki.platform:xwiki-platform-attachment-ui (Maven): affected from 2.0-rc-2; fixed in 13.10.11\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-2023-29516/ (Markdown: https://insights.sbomify.com/CVE-2023-29516/index.md)","id":"CVE-2023-29516","markdown":"https://insights.sbomify.com/CVE-2023-29516/index.md","name":"CVE-2023-29516","record":{"aliases":["GHSA-3989-4c6x-725f"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki platform","requires_auth":"low_privilege","summary":"Users with view rights can execute arbitrary code via improper escaping in the attachment selector, leading to full system access.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it.
