novel-plus through 5.3.3 Missing Authorization on the Admin Book Download Endpoint
cve-program · CVE-2026-90941 · Published
No access to your tenant or devices. Every item links to its source. What this means
novel-plus through 5.3.3 contains an authorization bypass vulnerability in the BookController download endpoint that allows authenticated backend accounts to export complete book text including paid chapters. Attackers can supply a bookId and bookName to retrieve all chapter content without VIP or purchase verification, bypassing the permission checks and data-scope limits enforced elsewhere in the admin interface.
Read the publisher's advisoryCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
See how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
