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-2023-29513 exists.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-web-templates (Maven): affected from 8.0-rc-1; fixed in 14.10.1\n- org.xwiki.platform:xwiki-platform-web-templates (Maven): affected from 8.0-rc-1; fixed in 14.10.1\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-2023-29513/ (Markdown: https://insights.sbomify.com/CVE-2023-29513/index.md)","id":"CVE-2023-29513","markdown":"https://insights.sbomify.com/CVE-2023-29513/index.md","name":"CVE-2023-29513","record":{"aliases":["GHSA-fp36-mjw5-fmgx"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki Platform","requires_auth":"low_privilege","summary":"Attackers can create unauthorized users via a template macro even when registration is disabled, leading to potential privilege escalation.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it.
