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-2026-50183 exists.\n\nAffected packages and fixed versions:\n- WWBN/AVideo (Packagist): affected all versions up to 29.0; no fix listed\n- WWBN/AVideo (Packagist): affected all versions up to 29.0; 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-2026-50183/ (Markdown: https://insights.sbomify.com/CVE-2026-50183/index.md)","id":"CVE-2026-50183","markdown":"https://insights.sbomify.com/CVE-2026-50183/index.md","name":"CVE-2026-50183","record":{"aliases":["GHSA-66q5-cj5g-wrfx"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"AVideo video platform","requires_auth":"none","summary":"Attackers can inject malicious scripts via YouTube video titles, leading to administrative account takeover in AVideo.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/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":"WWBN AVideo is an open source video platform. Versions 29.0 and below contain a stored Cross-Site Scripting vulnerability in the YouTubeAPI plugin. The plugin renders the snippet.title field returned by the YouTube Data API into the homepage gallery markup with no HTML encoding. The title is set by the YouTube video uploader (anyone in the world) and is treated by AVideo as trusted content. A YouTube uploader who controls a video matching the operator's configured query injects HTML into the AVideo homepage by setting their video's title to a JavaScript-bearing string; the payload then executes in the browser of every visitor who loads any page that renders the gallery. When the visitor is an AVideo administrator, the injected JavaScript performs any admin action (create user, promote to admin, change configuration, install plugin) that uses cookie-based authentication without an additional CSRF token, escalating the bug into full administrative takeover. The payload persists for the duration of cacheTimeout (default 3600 seconds) after the malicious title is set on YouTube and survives YouTube removing the hostile video for the same window. This issue has been addressed by commit https://github.com/WWBN/AVideo/commit/7292129eaee5f609beae103b5cb387d55f17b877.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"WWBN AVideo: Stored XSS via Hostile YouTube Video Title in AVideo YouTubeAPI Gallery Section","id":"CVE-2026-50183","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"Angular: Request Credential \u0026 Cache Policy Stripping in Angular Service Worker","id":"CVE-2026-50184"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["29.0"],"package":"WWBN/AVideo","purl":null,"source":"GHSA-66q5-cj5g-wrfx"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["29.0"],"package":"WWBN/AVideo","purl":"pkg:composer/WWBN/AVideo","source":"GHSA-66q5-cj5g-wrfx"}],"prev":{"headline":"AVideo Has Unauthenticated Reflected XSS via $_GET['search'] in YouTubeAPI Gallery Pagination","id":"CVE-2026-50182"},"products":["AVideo"],"published":"2026-07-15","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-16","vendors":["WWBN"]},"summary":"Attackers can inject malicious scripts via YouTube video titles, leading to administrative account takeover in AVideo.","url":"https://insights.sbomify.com/CVE-2026-50183/"}
