An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-26477 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-flamingo-theme-ui (Maven): affected from 14.0; fixed in 14.4.6\n- org.xwiki.platform:xwiki-platform-flamingo-theme-ui (Maven): affected from 14.0; fixed in 14.4.6\n- org.xwiki.platform:xwiki-platform-flamingo-theme-ui (Maven): affected from 14.5; fixed in 14.9-rc-1\n- org.xwiki.platform:xwiki-platform-flamingo-theme-ui (Maven): affected from 14.5; fixed in 14.9-rc-1\n- org.xwiki.platform:xwiki-platform-flamingo-theme-ui (Maven): affected from 6.2.4; fixed in 13.10.10\n- org.xwiki.platform:xwiki-platform-flamingo-theme-ui (Maven): affected from 6.2.4; fixed in 13.10.10\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-2023-26477/ (Markdown: https://insights.sbomify.com/CVE-2023-26477/index.md)","id":"CVE-2023-26477","markdown":"https://insights.sbomify.com/CVE-2023-26477/index.md","name":"CVE-2023-26477","record":{"aliases":["GHSA-x2qm-r4wx-8gpg"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki Platform","requires_auth":"none","summary":"Attackers can inject arbitrary Groovy, Python, or Velocity scripts via the newThemeName URL parameter in XWiki Platform, leading to remote code execution.","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":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-95","name":"Improper Neutralization of Directives in Dynamically Evaluated Code"}],"description":"XWiki Platform is a generic wiki platform. Starting in versions 6.3-rc-1 and 6.2.4, it's possible to inject arbitrary wiki syntax including Groovy, Python and Velocity script macros via the `newThemeName` request parameter (URL parameter), in combination with additional parameters. This has been patched in the supported versions 13.10.10, 14.9-rc-1, and 14.4.6.
