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-2026-85078 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- sanic (PyPI): affected all versions; fixed in 24.12.1, 25.12.1\n- sanic (PyPI): affected all versions; fixed in 24.12.1\n- sanic (PyPI): affected all versions; fixed in 24.12.1\n- sanic (PyPI): affected from 25.12.0; fixed in 25.12.1\n- sanic (PyPI): affected from 25.12.0; fixed in 25.12.1\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-2026-85078/ (Markdown: https://insights.sbomify.com/CVE-2026-85078/index.md)","id":"CVE-2026-85078","markdown":"https://insights.sbomify.com/CVE-2026-85078/index.md","name":"CVE-2026-85078","record":{"aliases":["GHSA-wmj6-g64g-j7q5","PYSEC-2026-4162"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Python web server","requires_auth":"none","summary":"Remote attackers can execute hidden second requests via HTTP request smuggling in Sanic, potentially bypassing security controls or executing code.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Sanic is an opensource python web server/framework. In version 25.12.0, Sanic's core HTTP/1.1 chunked-body handling does not fully consume the trailer-part after the terminating zero chunk before reusing the keep-alive connection buffer. A remote unauthenticated client can place attacker-controlled bytes in that trailer region, causing Sanic to parse and route them as a hidden second request after the outer request. This breaks HTTP request-boundary integrity and can provide a request-smuggling primitive when Sanic is deployed behind intermediaries.
