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-2025-55243 in the wild and no public exploit code.\n\nAffected product: Microsoft OfficePLUS. 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-2025-55243/ (Markdown: https://insights.sbomify.com/CVE-2025-55243/index.md)","id":"CVE-2025-55243","markdown":"https://insights.sbomify.com/CVE-2025-55243/index.md","name":"CVE-2025-55243","record":{"aliases":["GHSA-xrfp-hm62-qxmv"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft OfficePLUS","requires_auth":"none","summary":"An unauthorized attacker can exploit sensitive information exposure in Microsoft OfficePLUS to perform network-based spoofing attacks.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"officeplus","vendor":"microsoft"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Exposure of sensitive information to an unauthorized actor in Microsoft Office Plus allows an unauthorized attacker to perform spoofing over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Microsoft OfficePlus Spoofing Vulnerability","id":"CVE-2025-55243","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Azure Bot Service Elevation of Privilege Vulnerability","id":"CVE-2025-55244"},"packages":[],"prev":{"headline":"Xbox Certification Bug Copilot Djando Information Disclosure Vulnerability","id":"CVE-2025-55242"},"products":["Microsoft OfficePLUS"],"published":"2025-09-09","related":[{"cvss_score":7.8,"headline":"Microsoft OfficePlus Elevation of Privilege Vulnerability","id":"CVE-2024-38084","kev_date_added":null,"published":"2024-08-13"}],"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)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-02-20","vendors":["Microsoft"]},"summary":"An unauthorized attacker can exploit sensitive information exposure in Microsoft OfficePLUS to perform network-based spoofing attacks.","url":"https://insights.sbomify.com/CVE-2025-55243/"}
