{"id":"CVE-2026-89247","state":"PUBLISHED","title":"WWBN AVideo XML Injection via plugin/AD_Server/VMAP.php","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 <vmap:AdBreak> and <vmap:AdTagURI>/AdSource nodes into the generated XML. The player's IMA path (afterVideoJS -> 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.","publishedAt":"2026-09-11T11:15:26.580Z","updatedAt":"2026-09-15T16:11:31.860Z","severity":{"score":5.3,"label":"Medium","version":"4.0","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","source":"VulnCheck"},"assigner":"VulnCheck","products":["WWBN AVideo"],"affected":[{"vendor":"WWBN","product":"AVideo","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"c3edcc274c389816d434acadac07ee78eaf330c1","versionType":"git"}]}],"references":["https://github.com/WWBN/AVideo/security/advisories/GHSA-whh8-w65x-9fvx","https://www.vulncheck.com/advisories/wwbn-avideo-xml-injection-via-plugin-ad-server-vmap-php"],"weaknesses":["CWE-91"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/89xxx/CVE-2026-89247.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-89247","state":"PUBLISHED","datePublished":"2026-09-11T11:15:26.580Z","dateUpdated":"2026-09-15T16:11:31.860Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-11T10:51:31.663Z"},"containers":{"cna":{"title":"WWBN AVideo XML Injection via plugin/AD_Server/VMAP.php","descriptions":[{"lang":"en","value":"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.
