An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-8848 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-2025-8848/ (Markdown: https://insights.sbomify.com/CVE-2025-8848/index.md)","id":"CVE-2025-8848","markdown":"https://insights.sbomify.com/CVE-2025-8848/index.md","name":"CVE-2025-8848","record":{"aliases":["GHSA-xqvm-m8v9-8w9h"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"LibreChat web app","requires_auth":"high_privilege","summary":"Attackers can inject arbitrary HTML via the Accept-Language header, potentially leading to cross-site scripting attacks against logged-in users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntr_ai","cpe":[{"product":"librechat","vendor":"librechat"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"A vulnerability in danny-avila/librechat version 0.7.9 allows for HTML injection via the Accept-Language header.
