An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-4520 exists.\n\nAffected product: gaizhenbiao/chuanhuchatgpt. 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-2024-4520/ (Markdown: https://insights.sbomify.com/CVE-2024-4520/index.md)","id":"CVE-2024-4520","markdown":"https://insights.sbomify.com/CVE-2024-4520/index.md","name":"CVE-2024-4520","record":{"aliases":["GHSA-84rm-429m-4rw9"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"ChatGPT web application","requires_auth":"none","summary":"Attackers can access other users' chat histories without authorization, exposing sensitive personal and financial data.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntr_ai","cpe":[{"product":"chuanhuchatgpt","vendor":"gaizhenbiao"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"An improper access control vulnerability exists in the gaizhenbiao/chuanhuchatgpt application, specifically in version 20240410. This vulnerability allows any user on the server to access the chat history of any other user without requiring any form of interaction between the users. Exploitation of this vulnerability could lead to data breaches, including the exposure of sensitive personal details, financial data, or confidential conversations. Additionally, it could facilitate identity theft and manipulation or fraud through the unauthorized access to users' chat histories. This issue is due to insufficient access control mechanisms in the application's handling of chat history data.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Improper Access Control in gaizhenbiao/chuanhuchatgpt","id":"CVE-2024-4520","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Campcodes Complete Web-Based School Management System teacher_salary_details2.php cross site scripting","id":"CVE-2024-4521"},"packages":[],"prev":{"headline":"Campcodes Complete Web-Based School Management System teacher_salary_details3.php cross site scripting","id":"CVE-2024-4519"},"products":["gaizhenbiao/chuanhuchatgpt"],"published":"2024-06-04","related":[{"cvss_score":9.8,"headline":"Path Traversal in gaizhenbiao/chuanhuchatgpt","id":"CVE-2024-3234","kev_date_added":null,"published":"2024-06-06"},{"cvss_score":9.1,"headline":"Path Traversal in gaizhenbiao/chuanhuchatgpt","id":"CVE-2024-5982","kev_date_added":null,"published":"2024-10-29"},{"cvss_score":8.2,"headline":"Path Traversal in gaizhenbiao/chuanhuchatgpt","id":"CVE-2024-6255","kev_date_added":null,"published":"2024-07-31"},{"cvss_score":8.1,"headline":"Improper Access Control in gaizhenbiao/chuanhuchatgpt","id":"CVE-2024-8613","kev_date_added":null,"published":"2025-03-20"},{"cvss_score":8.1,"headline":"Authentication Bypass in gaizhenbiao/ChuanhuChatGPT","id":"CVE-2024-9216","kev_date_added":null,"published":"2025-03-20"},{"cvss_score":7.5,"headline":"Denial of Service (DoS) in gaizhenbiao/chuanhuchatgpt","id":"CVE-2024-10650","kev_date_added":null,"published":"2025-03-20"},{"cvss_score":7.5,"headline":"Denial of Service (DOS) in gaizhenbiao/chuanhuchatgpt","id":"CVE-2024-7807","kev_date_added":null,"published":"2024-10-29"}],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-15","vendors":["gaizhenbiao"]},"summary":"Attackers can access other users' chat histories without authorization, exposing sensitive personal and financial data.","url":"https://insights.sbomify.com/CVE-2024-4520/"}
