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-2025-4035 exists.\n\nAffected product: Red Hat Enterprise Linux 10. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2025-4035/ (Markdown: https://insights.sbomify.com/CVE-2025-4035/index.md)","id":"CVE-2025-4035","markdown":"https://insights.sbomify.com/CVE-2025-4035/index.md","name":"CVE-2025-4035","record":{"aliases":["AZL-61665","AZL-61670","DEBIAN-CVE-2025-4035","ECHO-bb6e-a23a-d95a","GHSA-9685-44wp-34gm","ROOT-OS-DEBIAN-13-CVE-2025-4035","UBUNTU-CVE-2025-4035"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"HTTP client library","requires_auth":"none","summary":"Attackers can bypass public suffix protections to set cookies for unauthorized domains, enabling session fixation attacks.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-178","name":"Improper Handling of Case Sensitivity"}],"description":"A flaw was found in libsoup.
