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-2024-10549 exists.\n\nAffected packages and fixed versions:\n- h2o (PyPI): affected from 3.30.0.7 up to 3.46.0.1; no fix listed\n- h2o (PyPI): affected from 3.30.0.7 up to 3.46.0.1; no fix listed\n- h2o (PyPI): affected from 3.30.0.7 up to 3.46.0.1; no fix listed\n- ai.h2o:h2o-core (Maven): affected from 3.30.0.7 up to 3.46.0.1; no fix listed\n- ai.h2o:h2o-core (Maven): affected from 3.30.0.7 up to 3.46.0.1; 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-2024-10549/ (Markdown: https://insights.sbomify.com/CVE-2024-10549/index.md)","id":"CVE-2024-10549","markdown":"https://insights.sbomify.com/CVE-2024-10549/index.md","name":"CVE-2024-10549","record":{"aliases":["GHSA-wwr9-4gmr-xvq9","PYSEC-2026-1445"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"H2O-3 machine learning library","requires_auth":"none","summary":"An attacker can cause a denial of service in H2O-3 by sending simultaneous requests to the Parse endpoint, exhausting threads via ReDoS.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntr_ai","cpe":[{"product":"h2o","vendor":"h2o"}],"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-1333","name":"Inefficient Regular Expression Complexity"}],"description":"A vulnerability in the `/3/Parse` endpoint of h2oai/h2o-3 version 3.46.0.1 allows for a denial of service (DoS) attack.
