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-2026-4276 in the wild and no public exploit code.\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-2026-4276/ (Markdown: https://insights.sbomify.com/CVE-2026-4276/index.md)","id":"CVE-2026-4276","markdown":"https://insights.sbomify.com/CVE-2026-4276/index.md","name":"CVE-2026-4276","record":{"aliases":["GHSA-hx3h-9mjj-5pmg"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"LibreChat RAG API","requires_auth":"none","summary":"Attackers can forge log entries in LibreChat RAG API via log injection, compromising audit trails and potentially misleading security monitoring.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"librechat","vendor":"librechat"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"LibreChat RAG API, version 0.7.0, contains a log-injection vulnerability that allows attackers to forge log entries.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"LibreChat RAG API, version 0.7.0, contains a log-injection vulnerability that allows attackers to forge log entries.","id":"CVE-2026-4276","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"librechat:librechat","products":["librechat:librechat"],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege abuse in GenericInlineModelAdmin","id":"CVE-2026-4277"},"packages":[],"prev":{"headline":"Cross-site request forgery in Divi Torque Lite – Divi Modules for the Divi Builder \u0026 Theme","id":"CVE-2026-4275"},"products":["RAG API"],"published":"2026-03-16","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-17","vendors":["LibreChat"]},"summary":"Attackers can forge log entries in LibreChat RAG API via log injection, compromising audit trails and potentially misleading security monitoring.","url":"https://insights.sbomify.com/CVE-2026-4276/"}
