Any signed-in user can exploit it over the network, 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-2023-4820 exists.\n\nAffected product: Unknown PowerPress Podcasting plugin by Blubrry. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2023-4820/ (Markdown: https://insights.sbomify.com/CVE-2023-4820/index.md)","id":"CVE-2023-4820","markdown":"https://insights.sbomify.com/CVE-2023-4820/index.md","name":"CVE-2023-4820","record":{"aliases":["GHSA-hfr4-7364-jv2q"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Contributors can inject arbitrary web scripts via the media URL field, potentially targeting site administrators.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"powerpress","vendor":"blubrry"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"The PowerPress Podcasting plugin by Blubrry WordPress plugin before 11.0.12 does not sanitize and escape the media url field in posts, which could allow users with privileges as low as contributor to inject arbitrary web scripts that could target a site admin or superadmin.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"PowerPress Podcasting \u003c 11.0.12 - Contributor+ Stored XSS","id":"CVE-2023-4820","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Drag and Drop Multiple File Upload \u003c 1.1.1 - Unauthenticated Stored Cross-Site Scripting","id":"CVE-2023-4821"},"packages":[],"prev":{"headline":"Shared Files \u003c 1.7.6 - Unauthenticated Stored Cross-Site Scripting","id":"CVE-2023-4819"},"products":["PowerPress Podcasting plugin by Blubrry"],"published":"2023-10-16","related":[{"cvss_score":7.2,"headline":"PowerPress \u003c 8.3.8 - Authenticated Arbitrary File Upload leading to RCE","id":"CVE-2021-24123","kev_date_added":null,"published":"2021-03-18"},{"cvss_score":6.4,"headline":"WordPress PowerPress Podcasting Plugin \u003c= 11.0.6 is vulnerable to Server Side Request Forgery (SSRF)","id":"CVE-2023-41239","kev_date_added":null,"published":"2023-11-13"},{"cvss_score":5.9,"headline":"PowerPress Podcasting \u003c 11.9.18 - Author+ XSS via Podcast URL","id":"CVE-2024-9230","kev_date_added":null,"published":"2025-04-14"},{"cvss_score":5.5,"headline":"WordPress PowerPress Podcasting Plugin \u003c= 10.0.1 is vulnerable to Cross Site Scripting (XSS)","id":"CVE-2023-30778","kev_date_added":null,"published":"2023-08-15"},{"cvss_score":5.4,"headline":"PowerPress \u003c= 10.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode","id":"CVE-2023-1917","kev_date_added":null,"published":"2023-06-09"},{"cvss_score":5.4,"headline":"Cross-site scripting in n/a","id":"CVE-2015-9410","kev_date_added":null,"published":"2019-09-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-05","vendors":["Unknown"]},"summary":"Contributors can inject arbitrary web scripts via the media URL field, potentially targeting site administrators.","url":"https://insights.sbomify.com/CVE-2023-4820/"}
