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-2026-89247 exists.\n\nAffected product: WWBN AVideo. 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-2026-89247/ (Markdown: https://insights.sbomify.com/CVE-2026-89247/index.md)","id":"CVE-2026-89247","markdown":"https://insights.sbomify.com/CVE-2026-89247/index.md","name":"CVE-2026-89247","record":{"aliases":["GHSA-m43h-5r7h-8gjg","GHSA-whh8-w65x-9fvx"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Video streaming platform","requires_auth":"none","summary":"Remote attackers can inject malicious XML into video ads via unauthenticated requests, potentially leading to code execution or data theft.","user_interaction":"required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-91","name":"XML Injection"}],"description":"WWBN AVideo at commit c3edcc274c389816d434acadac07ee78eaf330c1 and earlier contains an XML injection vulnerability in plugin/AD_Server/VMAP.php, which is reachable without authentication when the AD_Server plugin is enabled. The script emits Content-Type: application/xml and writes the timeOffset and idTag values returned by AD_Server::getVMAPSFromRequest() directly into VMAP attributes without encoding. Those values originate from the base64- and JSON-decoded $_REQUEST['vmaps'] parameter, which is not covered by $securityFilter in objects/security.php. A remote attacker can craft a vmaps value (containing a non-empty VAST.campaing entry) and induce a user to open the resulting VMAP URL or a video page using it, injecting arbitrary \u003cvmap:AdBreak\u003e and \u003cvmap:AdTagURI\u003e/AdSource nodes into the generated XML. The player's IMA path (afterVideoJS -\u003e PlayerSkins::setIMAADTag) then requests the attacker-supplied ad URLs, resulting in ad injection and cross-origin requests from the victim's playback session. The issue was unfixed at the time of reporting.","ecosystems":[],"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 XML Injection via plugin/AD_Server/VMAP.php","id":"CVE-2026-89247","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"AVideo WebRTC Plugin Information Disclosure via status.json.php","id":"CVE-2026-89248"},"packages":[],"prev":{"headline":"WWBN AVideo CSV Formula Injection via myComments.download.php","id":"CVE-2026-89246"},"products":["AVideo"],"published":"2026-09-11","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-15","vendors":["WWBN"]},"summary":"Remote attackers can inject malicious XML into video ads via unauthenticated requests, potentially leading to code execution or data theft.","url":"https://insights.sbomify.com/CVE-2026-89247/"}
