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-2023-2887 in the wild and no public exploit code.\n\nAffected product: CBOT Chatbot. 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-2023-2887/ (Markdown: https://insights.sbomify.com/CVE-2023-2887/index.md)","id":"CVE-2023-2887","markdown":"https://insights.sbomify.com/CVE-2023-2887/index.md","name":"CVE-2023-2887","record":{"aliases":["GHSA-93j5-g9f6-h7xv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"CBOT Chatbot","requires_auth":"none","summary":"Attackers can bypass authentication in CBOT Chatbot via spoofing, gaining unauthorized access to the system.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TR-CERT","cpe":[{"product":"cbot_core","vendor":"cbot"},{"product":"cbot_panel","vendor":"cbot"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"Authentication Bypass by Spoofing vulnerability in CBOT Chatbot allows Authentication Bypass.\n\nThis issue affects Chatbot: before Core: v4.0.3.4 Panel: v4.0.3.7.","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":"User Authentication Bypass in CBOT's Chatbot","id":"CVE-2023-2887","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"PHPOK unrestricted upload","id":"CVE-2023-2888"},"packages":[],"prev":{"headline":"Cross-Site WebSocket Hijacking in CBOT's Chatbot","id":"CVE-2023-2886"},"products":["Chatbot"],"published":"2023-05-25","related":[{"cvss_score":9.8,"headline":"Privilege Escalation in CBOT's Chatbot","id":"CVE-2023-2882","kev_date_added":null,"published":"2023-05-25"},{"cvss_score":9.8,"headline":"Insecure Randomness in CBOT's Chatbot","id":"CVE-2023-2884","kev_date_added":null,"published":"2023-05-25"},{"cvss_score":8.8,"headline":"IDOR in CBOT's Chatbot","id":"CVE-2023-2883","kev_date_added":null,"published":"2023-05-25"},{"cvss_score":8.1,"headline":"Channel Accessible by Non-Endpoint in CBOT's Chatbot","id":"CVE-2023-2885","kev_date_added":null,"published":"2023-05-25"},{"cvss_score":4.3,"headline":"Cross-Site WebSocket Hijacking in CBOT's Chatbot","id":"CVE-2023-2886","kev_date_added":null,"published":"2023-05-25"}],"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":"total"},"state":"PUBLISHED","updated":"2026-05-22","vendors":["CBOT"]},"summary":"Attackers can bypass authentication in CBOT Chatbot via spoofing, gaining unauthorized access to the system.","url":"https://insights.sbomify.com/CVE-2023-2887/"}
