Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-7937 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- plone (PyPI): affected from 5.0 up to 5.2.1; no fix listed\n- plone (PyPI): affected from 5.0; fixed in 5.2.2\n- Plone (PyPI): affected from 5.0 up to 5.2.1; no fix listed\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-2020-7937/ (Markdown: https://insights.sbomify.com/CVE-2020-7937/index.md)","id":"CVE-2020-7937","markdown":"https://insights.sbomify.com/CVE-2020-7937/index.md","name":"CVE-2020-7937","record":{"aliases":["GHSA-8mc4-2xrc-g582","PYSEC-2020-86"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Plone CMS","requires_auth":"low_privilege","summary":"Privileged users can inject JavaScript into Plone titles, leading to script execution for other site visitors.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"plone","vendor":"plone"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"An XSS issue in the title field in Plone 5.0 through 5.2.1 allows users with a certain privilege level to insert JavaScript that will be executed when other users access the site.","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":"Plone cross site scripting (XSS)","id":"CVE-2020-7937","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"plone:plone","products":["plone:plone"],"type":"xss","year":"2020"},"n_packages":3,"n_references":4,"next":{"headline":"Plone Privilege Escallation","id":"CVE-2020-7938"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["5.0"],"last_affected":["5.2.1"],"package":"Plone","purl":null,"source":"GHSA-8mc4-2xrc-g582"},{"ecosystem":"PyPI","fixed":[],"introduced":["5.0"],"last_affected":["5.2.1"],"package":"plone","purl":"pkg:pypi/plone","source":"GHSA-8mc4-2xrc-g582"},{"ecosystem":"PyPI","fixed":["5.2.2"],"introduced":["5.0"],"last_affected":[],"package":"plone","purl":"pkg:pypi/plone","source":"PYSEC-2020-86"}],"prev":{"headline":"Plone Open Redirect Vulnerability","id":"CVE-2020-7936"},"products":["n/a"],"published":"2020-01-23","related":[{"cvss_score":9.9,"headline":"Incorrect Permission Assignment for Critical Resource in Plone","id":"CVE-2021-33509","kev_date_added":null,"published":"2021-05-21"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2020-35190","kev_date_added":null,"published":"2020-12-17"},{"cvss_score":9.8,"headline":"Plone Unauthenticated Write Vulnerability","id":"CVE-2020-7941","kev_date_added":null,"published":"2020-01-23"},{"cvss_score":9.3,"headline":"Zope Command Execution Vulnerability","id":"CVE-2011-3587","kev_date_added":null,"published":"2011-10-10"},{"cvss_score":8.8,"headline":"Server-Side Request Forgery in Plone CMS","id":"CVE-2021-33926","kev_date_added":null,"published":"2023-02-17"},{"cvss_score":8.8,"headline":"Improper Restriction of XML External Entity Reference in Plone","id":"CVE-2020-28734","kev_date_added":null,"published":"2020-12-30"},{"cvss_score":8.8,"headline":"SSRF attacks via tracebacks in Plone","id":"CVE-2020-28735","kev_date_added":null,"published":"2020-12-30"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Privileged users can inject JavaScript into Plone titles, leading to script execution for other site visitors.","url":"https://insights.sbomify.com/CVE-2020-7937/"}
