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-2019-9636 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. 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-2019-9636/ (Markdown: https://insights.sbomify.com/CVE-2019-9636/index.md)","id":"CVE-2019-9636","markdown":"https://insights.sbomify.com/CVE-2019-9636/index.md","name":"CVE-2019-9636","record":{"aliases":["ALPINE-CVE-2019-9636","DEBIAN-CVE-2019-9636","GHSA-v82r-hg27-h4wh","MGASA-2019-0148","PSF-2019-9","RHBA-2019:0763","RHBA-2019:0764","RHSA-2019:0710","RHSA-2019:0765","RHSA-2019:0806","RHSA-2019:0902","RHSA-2019:0997","RHSA-2019:1467","RHSA-2019:2980","RHSA-2019:3170","SUSE-SU-2019:0961-1","SUSE-SU-2019:0971-1","UBUNTU-CVE-2019-9636","openSUSE-SU-2019:1282-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Python standard library","requires_auth":"none","summary":"Attackers can craft URLs to trick Python's urllib into sending sensitive cookies or credentials to the wrong host, leading to information disclosure.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"leap","vendor":"opensuse"},{"product":"sun_zfs_storage_appliance_kit","vendor":"oracle"},{"product":"python","vendor":"python"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_eus","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_eus","vendor":"redhat"},{"product":"enterprise_linux_server_tus","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"openshift_container_platform","vendor":"redhat"},{"product":"virtualization","vendor":"redhat"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-173","name":"Improper Handling of Alternate Encoding"}],"description":"Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization.
