An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-66473 exists.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-rest-server (Maven): affected all versions; fixed in 16.10.11\n- org.xwiki.platform:xwiki-platform-rest-server (Maven): affected all versions; fixed in 16.10.11\n- org.xwiki.platform:xwiki-platform-rest-server (Maven): affected from 17.0.0-rc-1; fixed in 17.4.4\n- org.xwiki.platform:xwiki-platform-rest-server (Maven): affected from 17.0.0-rc-1; fixed in 17.4.4\n- org.xwiki.platform:xwiki-platform-rest-server (Maven): affected from 17.5.0-rc-1; fixed in 17.7.0-rc-1\n- org.xwiki.platform:xwiki-platform-rest-server (Maven): affected from 17.5.0-rc-1; fixed in 17.7.0-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-2025-66473/ (Markdown: https://insights.sbomify.com/CVE-2025-66473/index.md)","id":"CVE-2025-66473","markdown":"https://insights.sbomify.com/CVE-2025-66473/index.md","name":"CVE-2025-66473","record":{"aliases":["GHSA-cc84-q3v3-mhgf"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki platform","requires_auth":"none","summary":"Attackers can cause denial of service in XWiki by requesting unlimited items via REST APIs, leading to memory exhaustion and unavailability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"XWiki is an open-source wiki software platform. Versions 16.10.10 and below, 17.0.0-rc-1 through 17.4.3 and 17.5.0-rc-1 through 17.6.0 contain a REST API which doesn't enforce any limits for the number of items that can be requested in a single request at the moment. Depending on the number of pages in the wiki and the memory configuration, this can lead to slowness and unavailability of the wiki. As an example, the /rest/wikis/xwiki/spaces resource returns all spaces on the wiki by default, which are basically all pages.
