An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of PSF-2019-14 in the wild and no public exploit code.\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/PSF-2019-14/ (Markdown: https://insights.sbomify.com/PSF-2019-14/index.md)","id":"PSF-2019-14","markdown":"https://insights.sbomify.com/PSF-2019-14/index.md","name":"PSF-2019-14","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python standard library","requires_auth":"none","summary":"A malicious HTTP server can cause extreme CPU usage and block execution in Python applications parsing Set-Cookie headers via a vulnerable regex.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The regex ``http.cookiejar.LOOSE_HTTP_DATE_RE`` is vulnerable to regular\nexpression denial of service (\"REDoS\"). ``LOOSE_HTTP_DATE_RE.match()`` is\ncalled when using ``http.cookiejar.CookieJar`` to parse ``Set-Cookie``\nheaders returned by a HTTP server.
