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-2026-7644 exists.\n\nAffected product: ChatGPTNextWeb NextChat. 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-2026-7644/ (Markdown: https://insights.sbomify.com/CVE-2026-7644/index.md)","id":"CVE-2026-7644","markdown":"https://insights.sbomify.com/CVE-2026-7644/index.md","name":"CVE-2026-7644","record":{"aliases":["GHSA-2jqp-6hx7-phh8"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"NextChat web application","requires_auth":"none","summary":"Attackers can exploit improper authorization in the addMcpServer function to perform unauthorized actions, potentially leading to privilege escalation or code execution.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"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:P","version":"4.0"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"},{"id":"CWE-266","name":"Incorrect Privilege Assignment"}],"description":"A vulnerability has been found in ChatGPTNextWeb NextChat up to 2.16.1.
