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-2011-4139 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- django (PyPI): affected all versions; fixed in 1.2.7, 1.3.1\n- django (PyPI): affected all versions; fixed in 1.2.7\n- django (PyPI): affected from 1.3; fixed in 1.3.1\n- Django (PyPI): affected all versions; fixed in 1.2.7\n- Django (PyPI): affected from 1.3; fixed in 1.3.1\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-2011-4139/ (Markdown: https://insights.sbomify.com/CVE-2011-4139/index.md)","id":"CVE-2011-4139","markdown":"https://insights.sbomify.com/CVE-2011-4139/index.md","name":"CVE-2011-4139","record":{"aliases":["DEBIAN-CVE-2011-4139","GHSA-rm2j-x595-q9cj","PYSEC-2011-4"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Django web framework","requires_auth":"none","summary":"Remote attackers can poison caches by manipulating the HTTP Host header in Django applications, potentially serving malicious content to users.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"django","vendor":"djangoproject"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Django before 1.2.7 and 1.3.x before 1.3.1 uses a request's HTTP Host header to construct a full URL in certain circumstances, which allows remote attackers to conduct cache poisoning attacks via a crafted request.","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":"Django Vulnerable to Cache Poisoning","id":"CVE-2011-4139","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"djangoproject:django","products":["djangoproject:django"],"type":"other","year":"2011"},"n_packages":5,"n_references":8,"next":{"headline":"Django Cross-Site Request Forgery vulnerability","id":"CVE-2011-4140"},"packages":[{"ecosystem":"PyPI","fixed":["1.2.7"],"introduced":["0"],"last_affected":[],"package":"Django","purl":null,"source":"GHSA-rm2j-x595-q9cj"},{"ecosystem":"PyPI","fixed":["1.3.1"],"introduced":["1.3"],"last_affected":[],"package":"Django","purl":null,"source":"GHSA-rm2j-x595-q9cj"},{"ecosystem":"PyPI","fixed":["1.2.7","1.3.1"],"introduced":["0","1.3"],"last_affected":[],"package":"django","purl":"pkg:pypi/django","source":"PYSEC-2011-4"},{"ecosystem":"PyPI","fixed":["1.2.7"],"introduced":["0"],"last_affected":[],"package":"django","purl":"pkg:pypi/django","source":"GHSA-rm2j-x595-q9cj"},{"ecosystem":"PyPI","fixed":["1.3.1"],"introduced":["1.3"],"last_affected":[],"package":"django","purl":"pkg:pypi/django","source":"GHSA-rm2j-x595-q9cj"}],"prev":{"headline":"Django Might Allow CSRF Requests via URL Verification","id":"CVE-2011-4138"},"products":["n/a"],"published":"2011-10-19","related":[{"cvss_score":9.8,"headline":"Privilege abuse in GenericInlineModelAdmin","id":"CVE-2026-4277","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":9.8,"headline":"Django SQL injection in HasKey(lhs, rhs) on Oracle","id":"CVE-2024-53908","kev_date_added":null,"published":"2024-12-06"},{"cvss_score":9.8,"headline":"Django SQL injection vulnerability","id":"CVE-2024-42005","kev_date_added":null,"published":"2024-08-07"},{"cvss_score":9.8,"headline":"Django bypasses validation when using one form field to upload multiple files","id":"CVE-2023-31047","kev_date_added":null,"published":"2023-05-07"},{"cvss_score":9.8,"headline":"Django `Trunc()` and `Extract()` database functions vulnerable to SQL Injection","id":"CVE-2022-34265","kev_date_added":null,"published":"2022-07-04"},{"cvss_score":9.8,"headline":"SQL Injection in Django","id":"CVE-2021-35042","kev_date_added":null,"published":"2021-07-02"},{"cvss_score":9.8,"headline":"SQL injection in Django","id":"CVE-2020-7471","kev_date_added":null,"published":"2020-02-03"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can poison caches by manipulating the HTTP Host header in Django applications, potentially serving malicious content to users.","url":"https://insights.sbomify.com/CVE-2011-4139/"}
