An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-10255 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jupyterhub (PyPI): affected all versions; fixed in 0.9.6\n- jupyterhub (PyPI): affected all versions; fixed in 0.9.6\n- jupyterhub (PyPI): affected all versions; fixed in 0.9.6\n- notebook (PyPI): affected all versions; fixed in 5.7.8\n- notebook (PyPI): affected all versions; fixed in 5.7.8\n- notebook (PyPI): affected all versions; fixed in 5.7.8\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-2019-10255/ (Markdown: https://insights.sbomify.com/CVE-2019-10255/index.md)","id":"CVE-2019-10255","markdown":"https://insights.sbomify.com/CVE-2019-10255/index.md","name":"CVE-2019-10255","record":{"aliases":["DEBIAN-CVE-2019-10255","GHSA-rv62-4pmj-xw6h","PYSEC-2026-2683","PYSEC-2026-647","UBUNTU-CVE-2019-10255"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Jupyter Notebook","requires_auth":"none","summary":"Crafted links to the login page redirect users to malicious sites after successful login, affecting Jupyter Notebook and Hub installations without a base_url prefix.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jupyterhub","vendor":"jupyter"},{"product":"notebook","vendor":"jupyter"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"An Open Redirect vulnerability for all browsers in Jupyter Notebook before 5.7.7 and some browsers (Chrome, Firefox) in JupyterHub before 0.9.5 allows crafted links to the login page, which will redirect to a malicious site after successful login.
