Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-48240 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-diff-xml (Maven): affected from 11.10.1; fixed in 14.10.15\n- org.xwiki.platform:xwiki-platform-diff-xml (Maven): affected from 11.10.1; fixed in 14.10.15\n- org.xwiki.platform:xwiki-platform-diff-xml (Maven): affected from 15.0-rc-1; fixed in 15.5.1\n- org.xwiki.platform:xwiki-platform-diff-xml (Maven): affected from 15.0-rc-1; fixed in 15.5.1\n- org.xwiki.platform:xwiki-platform-diff-xml (Maven): affected from 15.6-rc-1; fixed in 15.6\n- org.xwiki.platform:xwiki-platform-diff-xml (Maven): affected from 15.6-rc-1; fixed in 15.6\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-2023-48240/ (Markdown: https://insights.sbomify.com/CVE-2023-48240/index.md)","id":"CVE-2023-48240","markdown":"https://insights.sbomify.com/CVE-2023-48240/index.md","name":"CVE-2023-48240","record":{"aliases":["GHSA-7rfg-6273-f5wp"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki Platform","requires_auth":"low_privilege","summary":"Attackers can steal session cookies and access protected content via server-side request forgery in XWiki's rendered diff feature.","user_interaction":"required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-281","name":"Improper Preservation of Permissions"},{"id":"CWE-201","name":"Insertion of Sensitive Information Into Sent Data"}],"description":"XWiki Platform is a generic wiki platform. The rendered diff in XWiki embeds images to be able to compare the contents and not display a difference for an actually unchanged image. For this, XWiki requests all embedded images on the server side. These requests are also sent for images from other domains and include all cookies that were sent in the original request to ensure that images with restricted view right can be compared. Starting in version 11.10.1 and prior to versions 14.10.15, 15.5.1, and 15.6, this allows an attacker to steal login and session cookies that allow impersonating the current user who views the diff. The attack can be triggered with an image that references the rendered diff, thus making it easy to trigger. Apart from stealing login cookies, this also allows server-side request forgery (the result of any successful request is returned in the image's source) and viewing protected content as once a resource is cached, it is returned for all users. As only successful requests are cached, the cache will be filled by the first user who is allowed to access the resource. This has been patched in XWiki 14.10.15, 15.5.1 and 15.6. The rendered diff now only downloads images from trusted domains. Further, cookies are only sent when the image's domain is the same the requested domain. The cache has been changed to be specific for each user. As a workaround, the image embedding feature can be disabled by deleting `xwiki-platform-diff-xml-\u003cversion\u003e.jar` in `WEB-INF/lib/`.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"XWiki Platform sends cookies to external images in rendered diff and is vulnerable to server side request forgery","id":"CVE-2023-48240","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"xwiki:xwiki","products":["xwiki:xwiki"],"type":"ssrf","year":"2023"},"n_packages":6,"n_references":3,"next":{"headline":"XWiki exposed whole content of all documents of all wikis to anybody with view right on Solr suggest service","id":"CVE-2023-48241"},"packages":[{"ecosystem":"Maven","fixed":["14.10.15"],"introduced":["11.10.1"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-diff-xml","purl":null,"source":"GHSA-7rfg-6273-f5wp"},{"ecosystem":"Maven","fixed":["14.10.15"],"introduced":["11.10.1"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-diff-xml","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-diff-xml","source":"GHSA-7rfg-6273-f5wp"},{"ecosystem":"Maven","fixed":["15.5.1"],"introduced":["15.0-rc-1"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-diff-xml","purl":null,"source":"GHSA-7rfg-6273-f5wp"},{"ecosystem":"Maven","fixed":["15.5.1"],"introduced":["15.0-rc-1"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-diff-xml","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-diff-xml","source":"GHSA-7rfg-6273-f5wp"},{"ecosystem":"Maven","fixed":["15.6"],"introduced":["15.6-rc-1"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-diff-xml","purl":null,"source":"GHSA-7rfg-6273-f5wp"},{"ecosystem":"Maven","fixed":["15.6"],"introduced":["15.6-rc-1"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-diff-xml","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-diff-xml","source":"GHSA-7rfg-6273-f5wp"}],"prev":{"headline":"Nextcloud Server users can make external storage mount points inaccessible for other users","id":"CVE-2023-48239"},"products":["xwiki-platform"],"published":"2023-11-20","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-02","vendors":["xwiki"]},"summary":"Attackers can steal session cookies and access protected content via server-side request forgery in XWiki's rendered diff feature.","url":"https://insights.sbomify.com/CVE-2023-48240/"}
