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-2016-7036 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- python-jose (PyPI): affected all versions; fixed in 1.3.2\n- python-jose (PyPI): affected all versions; fixed in 1.3.2\n- python-jose (PyPI): affected all versions; fixed in 1.3.2\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-2016-7036/ (Markdown: https://insights.sbomify.com/CVE-2016-7036/index.md)","id":"CVE-2016-7036","markdown":"https://insights.sbomify.com/CVE-2016-7036/index.md","name":"CVE-2016-7036","record":{"aliases":["GHSA-w799-prg3-cx77","PYSEC-2017-28"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Python JOSE library","requires_auth":"none","summary":"Attackers can exploit timing side-channels in HMAC key comparison to bypass cryptographic verification in the python-jose library.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"python-jose","vendor":"python-jose_project"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-361","name":null}],"description":"python-jose before 1.3.2 allows attackers to have unspecified impact by leveraging failure to use a constant time comparison for HMAC keys.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"python-jose failure to use a constant time comparison for HMAC keys","id":"CVE-2016-7036","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"weak_cryptography","year":"2016"},"n_packages":3,"n_references":3,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2016-7037"},"packages":[{"ecosystem":"PyPI","fixed":["1.3.2"],"introduced":["0"],"last_affected":[],"package":"python-jose","purl":null,"source":"GHSA-w799-prg3-cx77"},{"ecosystem":"PyPI","fixed":["1.3.2"],"introduced":["0"],"last_affected":[],"package":"python-jose","purl":"pkg:pypi/python-jose","source":"GHSA-w799-prg3-cx77"},{"ecosystem":"PyPI","fixed":["1.3.2"],"introduced":["0"],"last_affected":[],"package":"python-jose","purl":"pkg:pypi/python-jose","source":"PYSEC-2017-28"}],"prev":{"headline":"Missing authorization in pacemaker","id":"CVE-2016-7035"},"products":["n/a"],"published":"2017-01-23","related":[{"cvss_score":6.5,"headline":"Security feature bypass in n/a","id":"CVE-2024-33663","kev_date_added":null,"published":"2024-04-25"},{"cvss_score":5.3,"headline":"Duplicate Advisory: python-jose denial of service via compressed JWE content","id":"CVE-2024-29370","kev_date_added":null,"published":"2025-12-17"},{"cvss_score":5.3,"headline":"python-jose denial of service via compressed JWE content","id":"CVE-2024-33664","kev_date_added":null,"published":"2024-04-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Attackers can exploit timing side-channels in HMAC key comparison to bypass cryptographic verification in the python-jose library.","url":"https://insights.sbomify.com/CVE-2016-7036/"}
