Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-83526 in the wild and no public exploit code.\n\nAffected product: foliovision FV Player 8. 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-2026-83526/ (Markdown: https://insights.sbomify.com/CVE-2026-83526/index.md)","id":"CVE-2026-83526","markdown":"https://insights.sbomify.com/CVE-2026-83526/index.md","name":"CVE-2026-83526","record":{"aliases":["GHSA-p776-3xx4-5fcg"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated subscribers can upload executable files via a race condition in FV Player, leading to remote code execution.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"The FV Player 8 plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 8.1.7 via the check_mimetype function. This is due to insufficient file type validation in check_mimetype(), which writes attacker-supplied remote file content to the public uploads directory before any MIME or extension check, combined with a missing capability check on new player creation. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. This requires successfully exploiting a race condition, and is only exploitable if the '[fvplayer_editor]' shortcode is present, or the \"Enable profile videos\" setting is enabled.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"File upload in FV Player 8","id":"CVE-2026-83526","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2026"},"n_packages":0,"n_references":11,"next":{"headline":"Auth bypass in Sentry","id":"CVE-2026-83527"},"packages":[],"prev":{"headline":"Incorrect operator (CWE-480) in the FetchSnapshot RPC handler in Apache Kafka from 2.8.0 before 4.2.2, and from 4.3.0 before 4.3.2 on all pl","id":"CVE-2026-83525"},"products":["FV Player 8"],"published":"2026-10-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-28","vendors":["foliovision"]},"summary":"Authenticated subscribers can upload executable files via a race condition in FV Player, leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2026-83526/"}
