CVE-2026-90940: Use of Default Credentials in 201206030 novel-plus
novel-plus versions up to 5.3.3 include a default cache-management password in the CacheController.refreshCache endpoint. This default credential allows anonymous attackers to invalidate portal caches by accessing the cache refresh URL with the hardcoded password. The vulnerability enables unauthorized cache invalidation, causing unnecessary database queries to repopulate the cache.
AI Analysis
Technical Summary
CVE-2026-90940 describes a vulnerability in novel-plus through version 5.3.3 where an insecure default password is hardcoded in the CacheController.refreshCache endpoint. This default credential can be used by unauthenticated attackers to trigger cache invalidation by supplying the known password in the URL path. The attack forces the system to perform unnecessary database queries to rebuild the cache, impacting availability but not confidentiality or integrity.
Potential Impact
The vulnerability allows anonymous attackers to cause denial of service by forcing repeated cache invalidations, leading to increased database load and potential performance degradation. There is no impact on confidentiality or integrity of data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the cache refresh endpoint or change the default cache-management password if possible to prevent unauthorized use.
