An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-105133 in the wild since at least 14 Oct 2026.\n\nAffected product: AhsayCBS. 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-2026-105133/ (Markdown: https://insights.sbomify.com/CVE-2026-105133/index.md)","id":"CVE-2026-105133","markdown":"https://insights.sbomify.com/CVE-2026-105133/index.md","name":"CVE-2026-105133","record":{"aliases":["GHSA-fp2j-3cmp-828j"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Backup server software","requires_auth":"none","summary":"Attackers can bypass authentication in the AhsayCBS API by manipulating the random argument, allowing unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"cloud_backup_suite","vendor":"ahsay"}],"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:L/VA:L/SC:N/SI:N/SA:N/E:A","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"A vulnerability was detected in Ahsay AhsayCBS up to 9.15.2.69/10.3.4.44.
