An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-69244 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- aiohttp (PyPI): affected all versions; fixed in 3.14.3\n- aiohttp (PyPI): affected all versions; fixed in 3.14.3\n- aiohttp (PyPI): affected all versions; fixed in 3.14.3\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-2026-69244/ (Markdown: https://insights.sbomify.com/CVE-2026-69244/index.md)","id":"CVE-2026-69244","markdown":"https://insights.sbomify.com/CVE-2026-69244/index.md","name":"CVE-2026-69244","record":{"aliases":["AZL-94553","CLEANSTART-2026-TB06618","CLSA-2026-1788347890","DEBIAN-CVE-2026-69244","ECHO-c0fa-407f-b85b","GHSA-cq5v-8q36-5273","MINI-276q-7f34-6q5v","MINI-332m-8jpm-x93v","MINI-5fj5-6ccq-3j4w","MINI-5w7g-3mxm-c368","MINI-66fh-jrq9-9gpr","MINI-6mqh-p9g4-59h3","MINI-79xv-353r-cmx6","MINI-7h88-4rvw-p8qc","MINI-96r5-rp8c-hr53","MINI-f724-6xwm-4hv8","MINI-fmqj-4w2r-3392","MINI-gp9c-r42q-8m3v","MINI-gqwv-363w-2f6h","MINI-jm48-8xhv-932g","MINI-jqc8-6fg2-g4vx","MINI-m22j-hw85-rfff","MINI-mfwj-rcx4-g6r9","MINI-mhj5-j4v6-56x8","MINI-pgpg-66wj-9wvm","MINI-pv8j-fv86-gq92","MINI-qwcx-v83v-fqqh","MINI-rwc4-jwhq-72w8","MINI-vvfh-5gwf-qr82","MINI-w3g4-vh5g-5gf3","MINI-wcxw-hq97-7v2h","MINI-wmx8-6rj8-v8p9","MINI-x5c7-8f4p-3xxm","PYSEC-2026-3545","ROOT-APP-PYPI-CVE-2026-69244","UBUNTU-CVE-2026-69244"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python HTTP library","requires_auth":"none","summary":"A malicious server can trigger an out-of-bounds heap read in the aiohttp client parser, causing a denial of service.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.3, an out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response. An attacker controlled server, or possibly an accidental response, could trigger a DoS in the client. The vulnerable path was error message construction in aiohttp/_http_parser.pyx, where an llhttp error-position pointer was used to build a snippet for malformed chunked responses and malformed request or response bytes at the buffer end.
