An attacker can exploit it over the internet without logging in, 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-2026-44681 exists.\n\nAffected packages and fixed versions:\n- authlib (PyPI): affected all versions; fixed in 1.6.12\n- authlib (PyPI): affected all versions; fixed in 1.6.12\n- authlib (PyPI): affected all versions; fixed in 1.6.12\n- authlib (PyPI): affected from 1.7.0; fixed in 1.7.1\n- authlib (PyPI): affected from 1.7.0; fixed in 1.7.1\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-2026-44681/ (Markdown: https://insights.sbomify.com/CVE-2026-44681/index.md)","id":"CVE-2026-44681","markdown":"https://insights.sbomify.com/CVE-2026-44681/index.md","name":"CVE-2026-44681","record":{"aliases":["CLEANSTART-2026-HL24999","CLEANSTART-2026-UZ98242","DEBIAN-CVE-2026-44681","ECHO-abd9-179e-e8ab","GHSA-r95x-qfjj-fjj2","MINI-pgrm-6cg6-9cp7","MINI-v5w2-r7mg-2ppx","PYSEC-2026-188","ROOT-APP-PYPI-CVE-2026-44681","UBUNTU-CVE-2026-44681","openSUSE-SU-2026:10883-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Python OAuth library","requires_auth":"none","summary":"An unauthenticated open redirect in Authlib's OIDC authorization endpoint allows attackers to redirect users to malicious URLs.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"authlib","vendor":"authlib"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Authlib is a Python library which builds OAuth and OpenID Connect servers.
