An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-5741 in the wild since at least 10 Mar 2023.\n\nAffected product: Plex Media Server (Windows). 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-2020-5741/ (Markdown: https://insights.sbomify.com/CVE-2020-5741/index.md)","id":"CVE-2020-5741","markdown":"https://insights.sbomify.com/CVE-2020-5741/index.md","name":"CVE-2020-5741","record":{"aliases":["GHSA-53fh-qcq6-xwhv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Plex Media Server","requires_auth":"high_privilege","summary":"A remote authenticated attacker can execute arbitrary Python code via unsafe deserialization in Plex Media Server on Windows.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"media_server","vendor":"plex"}],"cvss":{"score":7.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of Untrusted Data in Plex Media Server on Windows allows a remote, authenticated attacker to execute arbitrary Python code.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2020-05-07","github_poc":1,"max_poc_stars":0,"metasploit":1,"nuclei":0,"refs":[{"date":"2020-05-07","kind":"metasploit","ref":"exploit/windows/http/plex_unpickle_dict_rce","stars":null,"title":"Plex Unpickle Dict Windows RCE"},{"date":"2026-09-04T08:29:53Z","kind":"github_poc","ref":"https://github.com/HORKimhab/CVE-2025-34158-CVE-2020-5741","stars":0,"title":"CVE-2025-34158, CVE-2020-5741 - Draft or TODO"}],"tier":"exploited"},"has_fix":null,"headline":"Plex Media Server Remote Code Execution","id":"CVE-2020-5741","indexable":true,"kev":{"dateAdded":"2023-03-10","dueDate":"2023-03-31","knownRansomwareCampaignUse":"Unknown","product":"Media Server","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Plex","vulnerabilityName":"Plex Media Server Remote Code Execution Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site request forgery in Plex Media Server","id":"CVE-2020-5742"},"packages":[],"prev":{"headline":"Code injection in Plex Media Server (Windows)","id":"CVE-2020-5740"},"products":["Plex Media Server (Windows)"],"published":"2020-05-08","related":[{"cvss_score":8.6,"headline":"Plex Media Server External Control of File Name or Path","id":"CVE-2026-96656","kev_date_added":"2026-10-20","published":"2026-09-23"},{"cvss_score":6.9,"headline":"Plex Media Server Improper Neutralization of Encoded URI Schemes in a Web Page","id":"CVE-2026-96654","kev_date_added":"2026-10-20","published":"2026-09-23"},{"cvss_score":5.3,"headline":"Plex Media Server Server-Side Request Forgery (SSRF)","id":"CVE-2026-96652","kev_date_added":"2026-10-20","published":"2026-09-23"},{"cvss_score":5.3,"headline":"Plex Media Server Server-Side Request Forgery (SSRF)","id":"CVE-2026-96655","kev_date_added":"2026-10-20","published":"2026-09-23"},{"cvss_score":9.8,"headline":"XML external entity in n/a","id":"CVE-2018-13415","kev_date_added":null,"published":"2018-08-13"},{"cvss_score":8.8,"headline":"Cross-site request forgery in Plex Media Server","id":"CVE-2020-5742","kev_date_added":null,"published":"2020-06-15"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"A remote authenticated attacker can execute arbitrary Python code via unsafe deserialization in Plex Media Server on Windows.","url":"https://insights.sbomify.com/CVE-2020-5741/"}
