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-2025-71261 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/harvester/harvester (Go): affected all versions; fixed in 1.8.0\n- github.com/harvester/harvester (Go): affected all versions; fixed in 1.8.0\n- github.com/harvester/harvester (Go): affected all versions; fixed in 1.8.0\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-2025-71261/ (Markdown: https://insights.sbomify.com/CVE-2025-71261/index.md)","id":"CVE-2025-71261","markdown":"https://insights.sbomify.com/CVE-2025-71261/index.md","name":"CVE-2025-71261","record":{"aliases":["GHSA-pgh9-mpwc-8jjf","GO-2026-5538","MINI-75xf-pxmc-575r","MINI-95p2-4536-q6jp"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["security_bypass","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SUSE Harvester","requires_auth":"none","summary":"An attacker can bypass TLS security controls and cause denial of service in SUSE Harvester by interfering with the registration client's handshake.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"An attacker with network-level access between the SUSE Virtualization \nand Rancher Manager in SUSE Harvester before 1.8.0 could interfere with the TLS handshake and abuse it \nto bypass TLS as a security control.","ecosystems":["Go"],"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":"Harvester's SUSE Virtualization Registration Client Vulnerable to MITM and DOS","id":"CVE-2025-71261","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":3,"n_references":1,"next":{"headline":"Memory corruption in UNIX","id":"CVE-2025-71263"},"packages":[{"ecosystem":"Go","fixed":["1.8.0"],"introduced":["0"],"last_affected":[],"package":"github.com/harvester/harvester","purl":null,"source":"GHSA-pgh9-mpwc-8jjf"},{"ecosystem":"Go","fixed":["1.8.0"],"introduced":["0"],"last_affected":[],"package":"github.com/harvester/harvester","purl":"pkg:golang/github.com/harvester/harvester","source":"GHSA-pgh9-mpwc-8jjf"},{"ecosystem":"Go","fixed":["1.8.0"],"introduced":["0"],"last_affected":[],"package":"github.com/harvester/harvester","purl":"pkg:golang/github.com/harvester/harvester","source":"GO-2026-5538"}],"prev":{"headline":"BMC FootPrints ITSM 20.20.02 \u003c= 20.24.01.001 VIEWSTATE Deserialization RCE","id":"CVE-2025-71260"},"products":["Harvester"],"published":"2026-06-16","related":[],"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":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"2026-06-16","vendors":["SUSE"]},"summary":"An attacker can bypass TLS security controls and cause denial of service in SUSE Harvester by interfering with the registration client's handshake.","url":"https://insights.sbomify.com/CVE-2025-71261/"}
