Prior to version 1.0.8.6, Vvveb's HTML sanitizer fails to strip event-handler attributes when a tag carries a greater-than character inside a quoted attribute value. A low-privilege content author (default role author or contributor) can store a payload in post or product content that runs JavaScript in a browser of every visitor and of any administrator who views or previews that content, which opens a path to admin account takeover. This issue has been patched in version 1.0.8.6.","categories":["Unclassified"],"product":"Vvveb","vendor":"givanz","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55230","source_modified_at":"2026-10-01T19:23:19.200Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Vvveb","vendor":"givanz","versions":[{"version":"< 1.0.8.6","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00323,"percentile":0.24113,"score_date":"2026-10-23"},"published_at":"2026-10-01T18:42:50.082Z","modified_at":"2026-10-01T19:23:19.200Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55230","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T19:23:19.200Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55230","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/givanz/Vvveb/security/advisories/GHSA-97xr-82vc-wj2v","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/givanz/Vvveb/releases/tag/1.0.8.6","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-01T19:22:58.340870Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-01T19:23:19.200Z","content_hash":"f7479f4df09ece691a1400ac161d76eb3d2f7b451dcd2154db6576a60582262b"}}
