An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-13258 exists.\n\nAffected packages and fixed versions:\n- contentful (PyPI): affected all versions; fixed in 1.12.4\n- contentful (PyPI): affected all versions; fixed in 1.12.4\n- contentful (PyPI): affected all versions; fixed in 1.12.4\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-2020-13258/ (Markdown: https://insights.sbomify.com/CVE-2020-13258/index.md)","id":"CVE-2020-13258","markdown":"https://insights.sbomify.com/CVE-2020-13258/index.md","name":"CVE-2020-13258","record":{"aliases":["GHSA-g5j6-r3x9-gf2m","PYSEC-2026-626"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Python SDK","requires_auth":"none","summary":"Reflected XSS in the Contentful Python SDK allows attackers to execute arbitrary scripts via the api parameter.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"python_example","vendor":"contentful"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Contentful through 2020-05-21 for Python allows reflected XSS, as demonstrated by the api parameter to the-example-app.py.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2020/CVE-2020-13258.yaml","stars":null,"title":"Contentful \u003c=2020-05-21 - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":true,"headline":"Cross-site scripting in Contentful","id":"CVE-2020-13258","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":3,"n_references":1,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-13259"},"packages":[{"ecosystem":"PyPI","fixed":["1.12.4"],"introduced":["0"],"last_affected":[],"package":"contentful","purl":null,"source":"GHSA-g5j6-r3x9-gf2m"},{"ecosystem":"PyPI","fixed":["1.12.4"],"introduced":["0"],"last_affected":[],"package":"contentful","purl":"pkg:pypi/contentful","source":"GHSA-g5j6-r3x9-gf2m"},{"ecosystem":"PyPI","fixed":["1.12.4"],"introduced":["0"],"last_affected":[],"package":"contentful","purl":"pkg:pypi/contentful","source":"PYSEC-2026-626"}],"prev":{"headline":"Data leakage via cache key collision in Django","id":"CVE-2020-13254"},"products":["n/a"],"published":"2020-05-21","related":[],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Reflected XSS in the Contentful Python SDK allows attackers to execute arbitrary scripts via the api parameter.","url":"https://insights.sbomify.com/CVE-2020-13258/"}
