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-2023-43665 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- django (Bitnami): affected from 3.2.0; fixed in 3.2.22, 4.1.12, 4.2.6\n- django (PyPI): affected from 3.2; fixed in 3.2.22, 4.1.12, 4.2.6\n- django (PyPI): affected from 3.2a1; fixed in 3.2.22\n- django (PyPI): affected from 4.1a1; fixed in 4.1.12\n- django (PyPI): affected from 4.2a1; fixed in 4.2.6\n- Django (PyPI): affected from 3.2a1; fixed in 3.2.22\n- Django (PyPI): affected from 4.1a1; fixed in 4.1.12\n- Django (PyPI): affected from 4.2a1; fixed in 4.2.6\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-2023-43665/ (Markdown: https://insights.sbomify.com/CVE-2023-43665/index.md)","id":"CVE-2023-43665","markdown":"https://insights.sbomify.com/CVE-2023-43665/index.md","name":"CVE-2023-43665","record":{"aliases":["BIT-django-2023-43665","CLSA-2026-1784164007","DEBIAN-CVE-2023-43665","GHSA-h8gc-pgj2-vjm3","OESA-2023-1722","PYSEC-2023-226","SUSE-SU-2023:4232-1","SUSE-SU-2023:4426-1","UBUNTU-CVE-2023-43665","USN-6414-1","openSUSE-SU-2023:0309-1","openSUSE-SU-2023:0310-1","openSUSE-SU-2023:0389-1","openSUSE-SU-2023:0390-1","openSUSE-SU-2024:13334-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Django web framework","requires_auth":"none","summary":"Attackers can cause denial of service in Django applications by sending malformed HTML to specific text truncation utilities.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"django","vendor":"djangoproject"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1284","name":"Improper Validation of Specified Quantity in Input"}],"description":"In Django 3.2 before 3.2.22, 4.1 before 4.1.12, and 4.2 before 4.2.6, the django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text.
