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-2026-33035 exists.\n\nAffected packages and fixed versions:\n- wwbn/avideo (Packagist): affected all versions up to 25.0; no fix listed\n- wwbn/avideo (Packagist): affected all versions up to 25.0; 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-2026-33035/ (Markdown: https://insights.sbomify.com/CVE-2026-33035/index.md)","id":"CVE-2026-33035","markdown":"https://insights.sbomify.com/CVE-2026-33035/index.md","name":"CVE-2026-33035","record":{"aliases":["GHSA-wfq5-qgqp-hvhv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Video platform","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary JavaScript via reflected XSS in AVideo, leading to session theft and account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"avideo","vendor":"wwbn"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"WWBN AVideo is an open source video platform. In versions 25.0 and below, there is a reflected XSS vulnerability that allows unauthenticated attackers to execute arbitrary JavaScript in a victim's browser. User input from a URL parameter flows through PHP's json_encode() into a JavaScript function that renders it via innerHTML, bypassing encoding and achieving full script execution. The vulnerability is caused by two issues working together: unescaped user input passed to JavaScript (videoNotFound.php), and innerHTML rendering HTML tags as executable DOM (script.js).  The attack can be escalated to steal session cookies, take over accounts, phish credentials via injected login forms, spread self-propagating payloads, and compromise admin accounts — all by exploiting the lack of proper input sanitization and cookie security (e.g., missing HttpOnly flag on PHPSESSID). The issue has been fixed in version 26.0.","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":"Unauthenticated Reflected XSS via innerHTML in AVideo","id":"CVE-2026-33035","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"wwbn:avideo","products":["wwbn:avideo"],"type":"xss","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"fast-xml-parser affected by numeric entity expansion bypassing all entity expansion limits (incomplete fix for CVE-2026-26278)","id":"CVE-2026-33036"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["25.0"],"package":"wwbn/avideo","purl":null,"source":"GHSA-wfq5-qgqp-hvhv"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["25.0"],"package":"wwbn/avideo","purl":"pkg:composer/wwbn/avideo","source":"GHSA-wfq5-qgqp-hvhv"}],"prev":{"headline":"Potential denial-of-service vulnerability in ASGI requests via memory upload limit bypass","id":"CVE-2026-33034"},"products":["AVideo"],"published":"2026-03-20","related":[{"cvss_score":10,"headline":"WWBN AVideo YPTSocket WebSocket Broadcast Relay Leads to Unauthenticated Cross-User JavaScript Execution via Client-Side eval() Sinks","id":"CVE-2026-40911","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":10,"headline":"AVideo Multi-Chain Attack: Unauthenticated Remote Code Execution via Clone Key Disclosure, Database Dump, and Command Injection","id":"CVE-2026-33478","kev_date_added":null,"published":"2026-03-23"},{"cvss_score":9.9,"headline":"Command injection in AVideo","id":"CVE-2022-30534","kev_date_added":null,"published":"2022-08-22"},{"cvss_score":9.9,"headline":"Path traversal in AVideo","id":"CVE-2022-30547","kev_date_added":null,"published":"2022-08-22"},{"cvss_score":9.9,"headline":"Command injection in AVideo","id":"CVE-2022-32572","kev_date_added":null,"published":"2022-08-22"},{"cvss_score":9.8,"headline":"AVideo has an Unauthenticated SQL Injection via `doNotShowCats` Parameter (Backslash Escape Bypass)","id":"CVE-2026-33352","kev_date_added":null,"published":"2026-03-23"},{"cvss_score":9.8,"headline":"WWBN AVideo: Unauthenticated SQL Injection via JSON Request Bypass in objects/videos.json.php","id":"CVE-2026-28501","kev_date_added":null,"published":"2026-03-06"}],"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":"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-20","vendors":["WWBN"]},"summary":"Unauthenticated attackers can execute arbitrary JavaScript via reflected XSS in AVideo, leading to session theft and account takeover.","url":"https://insights.sbomify.com/CVE-2026-33035/"}
