An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-26478 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-store-filesystem-oldcore (Maven): affected from 14.3-rc-1; fixed in 14.4.6\n- org.xwiki.platform:xwiki-platform-store-filesystem-oldcore (Maven): affected from 14.3-rc-1; fixed in 14.4.6\n- org.xwiki.platform:xwiki-platform-store-filesystem-oldcore (Maven): affected from 14.5; fixed in 14.9-rc-1\n- org.xwiki.platform:xwiki-platform-store-filesystem-oldcore (Maven): affected from 14.5; fixed in 14.9-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-2023-26478/ (Markdown: https://insights.sbomify.com/CVE-2023-26478/index.md)","id":"CVE-2023-26478","markdown":"https://insights.sbomify.com/CVE-2023-26478/index.md","name":"CVE-2023-26478","record":{"aliases":["GHSA-8692-g6g9-gm5p"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki Platform","requires_auth":"high_privilege","summary":"Attackers can bypass programming rights checks to execute dangerous operations via exposed attachment methods in XWiki Platform.","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":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-749","name":"Exposed Dangerous Method or Function"}],"description":"XWiki Platform is a generic wiki platform.
