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-2025-27939 in the wild and no public exploit code.\n\nAffected product: Growatt Cloud portal. 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-2025-27939/ (Markdown: https://insights.sbomify.com/CVE-2025-27939/index.md)","id":"CVE-2025-27939","markdown":"https://insights.sbomify.com/CVE-2025-27939/index.md","name":"CVE-2025-27939","record":{"aliases":["GHSA-w6fv-xq82-cg7x"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Growatt Cloud portal","requires_auth":"none","summary":"An attacker can bypass authorization to change other users' email addresses and take over arbitrary accounts in the Growatt Cloud portal.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"cloud_portal","vendor":"growatt"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"An attacker can change registered email addresses of other users and take over arbitrary accounts.","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":"Growatt Cloud portal Authorization Bypass Through User-Controlled Key","id":"CVE-2025-27939","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in TDX Module","id":"CVE-2025-27940"},"packages":[],"prev":{"headline":"Growatt Cloud portal Authorization Bypass Through User-Controlled Key","id":"CVE-2025-27938"},"products":["Cloud portal"],"published":"2025-04-15","related":[{"cvss_score":9.3,"headline":"Growatt Cloud portal Cross-site Scripting","id":"CVE-2025-24297","kev_date_added":null,"published":"2025-04-15"},{"cvss_score":9.3,"headline":"Growatt Cloud portal Insufficient Type Distinction","id":"CVE-2025-30510","kev_date_added":null,"published":"2025-04-15"},{"cvss_score":8.7,"headline":"Growatt Cloud Applications Cross-site Scripting","id":"CVE-2025-30511","kev_date_added":null,"published":"2025-04-15"},{"cvss_score":6.9,"headline":"Growatt Cloud portal Authorization Bypass Through User-Controlled Key","id":"CVE-2025-24315","kev_date_added":null,"published":"2025-04-15"},{"cvss_score":6.9,"headline":"Growatt Cloud portal Authorization Bypass Through User-Controlled Key","id":"CVE-2025-24487","kev_date_added":null,"published":"2025-04-15"},{"cvss_score":6.9,"headline":"Growatt Cloud portal Authorization Bypass Through User-Controlled Key","id":"CVE-2025-24850","kev_date_added":null,"published":"2025-04-15"},{"cvss_score":6.9,"headline":"Growatt Cloud portal Authorization Bypass Through User-Controlled Key","id":"CVE-2025-25276","kev_date_added":null,"published":"2025-04-15"}],"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":"2025-04-16","vendors":["Growatt"]},"summary":"An attacker can bypass authorization to change other users' email addresses and take over arbitrary accounts in the Growatt Cloud portal.","url":"https://insights.sbomify.com/CVE-2025-27939/"}
