It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-85649 in the wild and no public exploit code.\n\nAffected product: chewkeanho software-actualizer. 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-2026-85649/ (Markdown: https://insights.sbomify.com/CVE-2026-85649/index.md)","id":"CVE-2026-85649","markdown":"https://insights.sbomify.com/CVE-2026-85649/index.md","name":"CVE-2026-85649","record":{"aliases":[],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Debian installer script","requires_auth":"high_privilege","summary":"An installer script fails to validate password hash generation, potentially creating system images with empty root passwords and allowing unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[],"cvss":{"score":7.9,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-636","name":"Not Failing Securely"},{"id":"CWE-252","name":"Unchecked Return Value"}],"description":"(Holloway) Chew, Kean Ho's Actualizer v1.2.0 and earlier contains a fail-open password validation vulnerability in the Alpha user and root user password loops of Shell/debian-minbase-install.sh. The installer invokes mkpasswd to generate yescrypt password hashes but does not check the command's return value and unconditionally accepts the result. If mkpasswd fails to generate a yescrypt hash, for example because an incompatible mkpasswd implementation or an environment without yescrypt support is used, the resulting password hash variable can be empty and the build proceeds. The resulting image can therefore contain empty password fields for the root and alpha accounts, potentially permitting passwordless authentication depending on the authentication configuration.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-09-04","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-04T22:54:32Z","kind":"github_poc","ref":"https://github.com/ChewKeanHo/research-cve-2026-85649","stars":1,"title":"[MIRROR] The CVE-2026-85649 Security Research Publication."}],"tier":"poc_unverified"},"has_fix":false,"headline":"Auth bypass in software-actualizer","id":"CVE-2026-85649","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Trigger.dev before 4.5.2 Server-Side Request Forgery via webhook alert-channel","id":"CVE-2026-85650"},"packages":[],"prev":{"headline":"Form Maker by 10Web – Mobile-Friendly Drag \u0026 Drop Contact Form Builder \u003c= 1.15.46 - Reflected Cross-Site Scripting","id":"CVE-2026-85645"},"products":["software-actualizer"],"published":"2026-09-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-04","vendors":["chewkeanho"]},"summary":"An installer script fails to validate password hash generation, potentially creating system images with empty root passwords and allowing unauthorized access.","url":"https://insights.sbomify.com/CVE-2026-85649/"}
