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-2025-32783 exists.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-messagestream (Maven): affected from 5.0 up to 16.7.1; no fix listed\n- org.xwiki.platform:xwiki-platform-messagestream (Maven): affected from 5.0 up to 16.7.1; no fix listed\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-2025-32783/ (Markdown: https://insights.sbomify.com/CVE-2025-32783/index.md)","id":"CVE-2025-32783","markdown":"https://insights.sbomify.com/CVE-2025-32783/index.md","name":"CVE-2025-32783","record":{"aliases":["GHSA-42fh-pvvh-999x"],"analysis":{"component_type":"web_application","fix_type":"workaround","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"XWiki Platform","requires_auth":"none","summary":"Unregistered users can view private messages from closed subwikis via the main wiki dashboard if Message Stream is enabled.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"}],"description":"XWiki Platform is a generic wiki platform. A vulnerability in versions from 5.0 to 16.7.1 affects users with Message Stream enabled and a wiki configured as closed from selecting \"Prevent unregistered users to view pages\" in the Administrations Rights. The vulnerability is that any message sent in a subwiki to \"everyone\" is actually sent to the farm: any visitor of the main wiki will be able to see that message through the Dashboard, even if the subwiki is configured to be private. This issue will not be patched as Message Stream has been deprecated in XWiki 16.8.0RC1 and is not maintained anymore. A workaround for this issue involves keeping Message Stream disabled by default. It's advised to keep it disabled from Administration \u003e Social \u003e Message Stream.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"XWiki allows unregistered users to see \"public\" messages from a closed wiki via notifications from a different wiki","id":"CVE-2025-32783","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"xwiki:xwiki","products":["xwiki:xwiki"],"type":"information_disclosure","year":"2025"},"n_packages":2,"n_references":2,"next":{"headline":"conda-forge-webservices has an Unauthorized Artifact Modification Race Condition","id":"CVE-2025-32784"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["5.0"],"last_affected":["16.7.1"],"package":"org.xwiki.platform:xwiki-platform-messagestream","purl":null,"source":"GHSA-42fh-pvvh-999x"},{"ecosystem":"Maven","fixed":[],"introduced":["5.0"],"last_affected":["16.7.1"],"package":"org.xwiki.platform:xwiki-platform-messagestream","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-messagestream","source":"GHSA-42fh-pvvh-999x"}],"prev":{"headline":"Ash Authentication email link auto-click account confirmation vulnerability","id":"CVE-2025-32782"},"products":["xwiki-platform"],"published":"2025-04-16","related":[{"cvss_score":9.8,"headline":"XWiki Platform Eval Injection","id":"CVE-2025-24893","kev_date_added":"2025-10-30","published":"2025-02-20"},{"cvss_score":10,"headline":"XWiki Rendering is vulnerable to RCE attacks when processing nested macros","id":"CVE-2025-53836","kev_date_added":null,"published":"2025-07-14"},{"cvss_score":10,"headline":"XWiki allows remote code execution through the extension sheet","id":"CVE-2024-55662","kev_date_added":null,"published":"2024-12-12"},{"cvss_score":10,"headline":"XWiki allows remote code execution from account through macro descriptions and XWiki.XWikiSyntaxMacrosList","id":"CVE-2024-55877","kev_date_added":null,"published":"2024-12-12"},{"cvss_score":10,"headline":"XWiki Platform vulnerable to remote code execution from account via SearchSuggestConfigSheet","id":"CVE-2024-37901","kev_date_added":null,"published":"2024-07-31"},{"cvss_score":10,"headline":"XWiki programming rights may be inherited by inclusion","id":"CVE-2024-38369","kev_date_added":null,"published":"2024-06-24"},{"cvss_score":10,"headline":"XWiki Platform: Remote code execution from account via SearchSuggestSourceSheet","id":"CVE-2024-31465","kev_date_added":null,"published":"2024-04-10"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-17","vendors":["xwiki"]},"summary":"Unregistered users can view private messages from closed subwikis via the main wiki dashboard if Message Stream is enabled.","url":"https://insights.sbomify.com/CVE-2025-32783/"}
