An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-40105 exists.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-web-templates (Maven): affected from 10.4-rc-1; fixed in 16.10.16\n- org.xwiki.platform:xwiki-platform-web-templates (Maven): affected from 10.4-rc-1; fixed in 16.10.16\n- org.xwiki.platform:xwiki-platform-web-templates (Maven): affected from 17.0.0-rc-1; fixed in 17.4.8\n- org.xwiki.platform:xwiki-platform-web-templates (Maven): affected from 17.0.0-rc-1; fixed in 17.4.8\n- org.xwiki.platform:xwiki-platform-web-templates (Maven): affected from 17.5.0-rc-1; fixed in 17.10.1\n- org.xwiki.platform:xwiki-platform-web-templates (Maven): affected from 17.5.0-rc-1; fixed in 17.10.1\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-2026-40105/ (Markdown: https://insights.sbomify.com/CVE-2026-40105/index.md)","id":"CVE-2026-40105","markdown":"https://insights.sbomify.com/CVE-2026-40105/index.md","name":"CVE-2026-40105","record":{"aliases":["GHSA-w4fj-87j5-f25c"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki platform","requires_auth":"none","summary":"Attackers can execute JavaScript in users' browsers via reflected XSS in page history comparison, potentially compromising admin accounts and the entire instance.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"}],"description":"XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it.
