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-2026-44889 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- webob (PyPI): affected all versions; fixed in 1.8.10\n- webob (PyPI): affected all versions; fixed in 1.8.10\n- webob (PyPI): affected all versions; fixed in 1.8.10\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-2026-44889/ (Markdown: https://insights.sbomify.com/CVE-2026-44889/index.md)","id":"CVE-2026-44889","markdown":"https://insights.sbomify.com/CVE-2026-44889/index.md","name":"CVE-2026-44889","record":{"aliases":["AZL-91362","DEBIAN-CVE-2026-44889","ECHO-0b2f-27c4-24aa","GHSA-fh3h-vg37-cc95","MGASA-2026-0452","OESA-2026-2679","PYSEC-2026-251","SUSE-SU-2026:22370-1","SUSE-SU-2026:2982-1","UBUNTU-CVE-2026-44889","openSUSE-SU-2026:11041-1","openSUSE-SU-2026:21063-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Python HTTP library","requires_auth":"none","summary":"An attacker can manipulate redirect locations to send users to arbitrary external sites, bypassing previous security fixes in the WebOb library.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"webob","vendor":"pylonsproject"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"WebOb provides objects for HTTP requests and responses. Prior to 1.8.10, the normalization of the HTTP Location header during a redirect is vulnerable to an open redirect: WebOb joins the redirect target to the request URI using Python's urljoin, and since Python 3.10 the underlying urlsplit strips ASCII tab, carriage return, and newline characters before parsing, so a redirect target containing such characters can be reinterpreted as a protocol-relative URL whose authority is an attacker-controlled host. This bypasses the CVE-2024-42353 fix that escaped a leading double slash, allowing an attacker who influences the redirect location to send users to an arbitrary external site instead of the intended one.
