Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-53691 exists.\n\nAffected product: Sitecore Experience Manager (XM). No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2025-53691/ (Markdown: https://insights.sbomify.com/CVE-2025-53691/index.md)","id":"CVE-2025-53691","markdown":"https://insights.sbomify.com/CVE-2025-53691/index.md","name":"CVE-2025-53691","record":{"aliases":["GHSA-cpg3-c796-vg5v"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Sitecore Experience Platform","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution in Sitecore Experience Manager and Platform via insecure deserialization of untrusted data.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wiz","cpe":[{"product":"experience_commerce","vendor":"sitecore"},{"product":"experience_manager","vendor":"sitecore"},{"product":"experience_platform","vendor":"sitecore"},{"product":"managed_cloud","vendor":"sitecore"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of Untrusted Data vulnerability in Sitecore Experience Manager (XM), Sitecore Experience Platform (XP) allows Remote Code Execution (RCE).This issue affects Experience Manager (XM): from 9.0 through 9.3, from 10.0 through 10.4; Experience Platform (XP): from 9.0 through 9.3, from 10.0 through 10.4.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-09-01","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-09-01T14:30:08Z","kind":"github_poc","ref":"https://github.com/blueisbeautiful/CVE-2025-53691","stars":0,"title":"Remote code execution (RCE) through insecure deserialization"}],"tier":"weaponised"},"has_fix":null,"headline":"Sitecore Experience Remote Code Execution through Insecure Deserialization","id":"CVE-2025-53691","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Sitecore Experience Platform Cross-Site Scripting Vulnerability","id":"CVE-2025-53692"},"packages":[],"prev":{"headline":"Sitecore Multiple Products Deserialization of Untrusted Data","id":"CVE-2025-53690"},"products":["Experience Manager (XM)","Experience Platform (XP)"],"published":"2025-09-03","related":[{"cvss_score":9,"headline":"Sitecore Multiple Products Deserialization of Untrusted Data","id":"CVE-2025-53690","kev_date_added":"2025-09-04","published":"2025-09-03"},{"cvss_score":9.8,"headline":"HTML Cache Poisoning through Unsafe Reflections","id":"CVE-2025-53693","kev_date_added":null,"published":"2025-09-03"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2023-35813","kev_date_added":null,"published":"2023-06-17"},{"cvss_score":8.8,"headline":"Sitecore XM, XC, and XP Post-Auth RCE via Zip Slip","id":"CVE-2025-34510","kev_date_added":null,"published":"2025-06-17"},{"cvss_score":8.8,"headline":"Sitecore PowerShell Extension RCE via Unrestricted Upload","id":"CVE-2025-34511","kev_date_added":null,"published":"2025-06-17"},{"cvss_score":7.5,"headline":"Information Disclosure in ItemServices API","id":"CVE-2025-53694","kev_date_added":null,"published":"2025-09-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-09-03","vendors":["Sitecore"]},"summary":"Attackers can achieve remote code execution in Sitecore Experience Manager and Platform via insecure deserialization of untrusted data.","url":"https://insights.sbomify.com/CVE-2025-53691/"}
