Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-54024 exists.\n\nAffected product: Librechat Librechat. 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-2026-54024/ (Markdown: https://insights.sbomify.com/CVE-2026-54024/index.md)","id":"CVE-2026-54024","markdown":"https://insights.sbomify.com/CVE-2026-54024/index.md","name":"CVE-2026-54024","record":{"aliases":["GHSA-52f6-fqwv-jccf"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"LibreChat web application","requires_auth":"low_privilege","summary":"Authenticated users can upload arbitrarily large files via the conversation import endpoint to exhaust server resources, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"librechat","vendor":"librechat"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the fix for CVE-2024-11171 (commit bb58a2d0) added limits: { fileSize } to createMulterInstance() in the file upload routes. However, the POST /api/convos/import endpoint uses a separate multer instance that was never updated with the same limits configuration. Combined with the application-level size check being disabled by default (the CONVERSATION_IMPORT_MAX_FILE_SIZE_BYTES env var is commented out in .env.example), an authenticated user can upload arbitrarily large files to exhaust server disk space and memory. This vulnerability is fixed in 0.8.4-rc1.","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":"LibreChat: Incomplete Fix for CVE-2024-11171 — Conversation Import Multer Instance Missing File Size Limits","id":"CVE-2026-54024","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"librechat:librechat","products":["librechat:librechat"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"LibreChat: Stored XSS via unescaped image alt text in markdown artifact preview","id":"CVE-2026-54025"},"packages":[],"prev":{"headline":"Open WebUI: Any authenticated user can read other users' private notes via Socket.IO","id":"CVE-2026-54022"},"products":["LibreChat"],"published":"2026-06-25","related":[{"cvss_score":9.6,"headline":"LibreChat Exfiltrates Server Secrets via MCP Server URL Injection","id":"CVE-2026-32625","kev_date_added":null,"published":"2026-06-02"},{"cvss_score":9.4,"headline":"Improper Access Control in danny-avila/librechat","id":"CVE-2024-11167","kev_date_added":null,"published":"2025-03-20"},{"cvss_score":9.1,"headline":"LibreChat MCP Stdio Remote Command Execution","id":"CVE-2026-22252","kev_date_added":null,"published":"2026-01-12"},{"cvss_score":9.1,"headline":"LibreChat is vulnerable to Server-Side Request Forgery due to missing restrictions","id":"CVE-2025-69222","kev_date_added":null,"published":"2026-01-07"},{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2024-41704","kev_date_added":null,"published":"2024-07-22"},{"cvss_score":8.8,"headline":"Path Traversal in danny-avila/librechat","id":"CVE-2024-11170","kev_date_added":null,"published":"2025-03-20"},{"cvss_score":8.6,"headline":"LibreChat JSON Injection in Chat POST Allows Remote Resource Inclusion and PXSS via Image Upload","id":"CVE-2025-66450","kev_date_added":null,"published":"2025-12-11"}],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-25","vendors":["danny-avila"]},"summary":"Authenticated users can upload arbitrarily large files via the conversation import endpoint to exhaust server resources, causing denial of service.","url":"https://insights.sbomify.com/CVE-2026-54024/"}
