Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-4934 in the wild and no public exploit code.\n\nAffected product: Usta AYBS. 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-2023-4934/ (Markdown: https://insights.sbomify.com/CVE-2023-4934/index.md)","id":"CVE-2023-4934","markdown":"https://insights.sbomify.com/CVE-2023-4934/index.md","name":"CVE-2023-4934","record":{"aliases":["GHSA-4cxm-9rxq-69rw"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"AYBS web application","requires_auth":"low_privilege","summary":"Attackers can bypass authentication and access unauthorized data in Usta AYBS due to insecure direct object references.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TR-CERT","cpe":[{"product":"aybs","vendor":"usta"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Authorization Bypass Through User-Controlled Key vulnerability in Usta AYBS allows Authentication Abuse, Authentication Bypass.\n\nThis issue affects AYBS: before 1.0.3.","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":"IDOR in Usta AYBS","id":"CVE-2023-4934","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"BEAR \u003c= 1.1.3.3 - Cross-Site Request Forgery to Profile Creation","id":"CVE-2023-4935"},"packages":[],"prev":{"headline":"WP Job Openings \u003c 3.4.3 - Sensitive Data Exposure via Directory Listing","id":"CVE-2023-4933"},"products":["AYBS"],"published":"2023-09-27","related":[],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-21","vendors":["Usta"]},"summary":"Attackers can bypass authentication and access unauthorized data in Usta AYBS due to insecure direct object references.","url":"https://insights.sbomify.com/CVE-2023-4934/"}
