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-2024-12704 exists.\n\nAffected packages and fixed versions:\n- llama-index-core (PyPI): affected all versions; fixed in 0.12.6\n- llama-index-core (PyPI): affected all versions; fixed in 0.12.6\n- llama-index-core (PyPI): affected all versions; fixed in 0.12.6\n- llama-index (PyPI): affected all versions up to 0.12.5; no fix listed\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-2024-12704/ (Markdown: https://insights.sbomify.com/CVE-2024-12704/index.md)","id":"CVE-2024-12704","markdown":"https://insights.sbomify.com/CVE-2024-12704/index.md","name":"CVE-2024-12704","record":{"aliases":["GHSA-j3wr-m6xh-64hg","PYSEC-2025-244","PYSEC-2026-1563"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python LLM library","requires_auth":"none","summary":"An attacker can cause a denial of service in the llama_index library by triggering an infinite loop through improper exception handling in streaming methods.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntr_ai","cpe":[{"product":"llamaindex","vendor":"llamaindex"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"A vulnerability in the LangChainLLM class of the run-llama/llama_index repository, version v0.12.5, allows for a Denial of Service (DoS) attack. The stream_complete method executes the llm using a thread and retrieves the result via the get_response_gen method of the StreamingGeneratorCallbackHandler class. If the thread terminates abnormally before the _llm.predict is executed, there is no exception handling for this case, leading to an infinite loop in the get_response_gen function. This can be triggered by providing an input of an incorrect type, causing the thread to terminate and the process to continue running indefinitely.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Denial of Service (DoS) in run-llama/llama_index","id":"CVE-2024-12704","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"denial_of_service","year":"2024"},"n_packages":4,"n_references":2,"next":{"headline":"DNS-over-HTTPS implementation suffers from multiple issues under heavy query load","id":"CVE-2024-12705"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.12.5"],"package":"llama-index","purl":"pkg:pypi/llama-index","source":"PYSEC-2025-244"},{"ecosystem":"PyPI","fixed":["0.12.6"],"introduced":["0"],"last_affected":[],"package":"llama-index-core","purl":null,"source":"GHSA-j3wr-m6xh-64hg"},{"ecosystem":"PyPI","fixed":["0.12.6"],"introduced":["0"],"last_affected":[],"package":"llama-index-core","purl":"pkg:pypi/llama-index-core","source":"GHSA-j3wr-m6xh-64hg"},{"ecosystem":"PyPI","fixed":["0.12.6"],"introduced":["0"],"last_affected":[],"package":"llama-index-core","purl":"pkg:pypi/llama-index-core","source":"PYSEC-2026-1563"}],"prev":{"headline":"Deserialization in RemoteConnect and SCADAPack x70 Utilities","id":"CVE-2024-12703"},"products":["run-llama/llama_index"],"published":"2025-03-20","related":[{"cvss_score":10,"headline":"SQL Injection to RCE in run-llama/llama_index","id":"CVE-2024-12909","kev_date_added":null,"published":"2025-03-20"},{"cvss_score":9.8,"headline":"SQL Injection in run-llama/llama_index","id":"CVE-2025-1793","kev_date_added":null,"published":"2025-06-05"},{"cvss_score":9.8,"headline":"SQL Injection in run-llama/llama_index","id":"CVE-2025-1750","kev_date_added":null,"published":"2025-06-02"},{"cvss_score":9.8,"headline":"SQL Injection in run-llama/llama_index","id":"CVE-2024-11958","kev_date_added":null,"published":"2025-03-20"},{"cvss_score":9.8,"headline":"Command Injection in run-llama/llama_index","id":"CVE-2024-3271","kev_date_added":null,"published":"2024-04-16"},{"cvss_score":9.8,"headline":"SQL injection in llama-index","id":"CVE-2024-23751","kev_date_added":null,"published":"2024-01-22"},{"cvss_score":8.8,"headline":"LlamaIndex includes an exec call for `import {cls_name}`","id":"CVE-2024-45201","kev_date_added":null,"published":"2024-08-22"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":["run-llama"]},"summary":"An attacker can cause a denial of service in the llama_index library by triggering an infinite loop through improper exception handling in streaming methods.","url":"https://insights.sbomify.com/CVE-2024-12704/"}
