Any signed-in user can exploit it over the network, 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-2025-68158 exists.\n\nAffected packages and fixed versions:\n- authlib (PyPI): affected from 1.0.0; fixed in 1.6.6\n- authlib (PyPI): affected from 1.0.0; fixed in 1.6.6\n- authlib (PyPI): affected from 1.0.0; fixed in 1.6.6\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-2025-68158/ (Markdown: https://insights.sbomify.com/CVE-2025-68158/index.md)","id":"CVE-2025-68158","markdown":"https://insights.sbomify.com/CVE-2025-68158/index.md","name":"CVE-2025-68158","record":{"aliases":["DEBIAN-CVE-2025-68158","ECHO-9727-a15c-fedd","GHSA-fg6f-75jq-6523","MINI-2ww7-2mrm-vvq5","MINI-739w-f9m4-9ppc","PYSEC-2026-1201","SUSE-SU-2026:0828-1","UBUNTU-CVE-2025-68158","openSUSE-SU-2026:10034-1","openSUSE-SU-2026:20257-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Python OAuth library","requires_auth":"low_privilege","summary":"Attackers can hijack user accounts via CSRF when cache-backed state storage is used, as state tokens are not tied to user sessions.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"authlib","vendor":"authlib"}],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Authlib is a Python library which builds OAuth and OpenID Connect servers. In versions 1.0.0 through 1.6.5, cache-backed state/request-token storage is not tied to the initiating user session, so CSRF is possible for any attacker that has a valid state (easily obtainable via an attacker-initiated authentication flow). When a cache is supplied to the OAuth client registry, FrameworkIntegration.set_state_data writes the entire state blob under _state_{app}_{state}, and get_state_data ignores the caller’s session altogether.
