CVE-2026-6241

MEDIUMPre-NVD 6.86.8
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 94% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

An authenticated format string vulnerability is present in the ONVIF AddScopes in Tapo C520WS v2, where user-controlled input is improperly passed to formatting functions without adequate sanitization. An attacker can inject format specifiers into ONVIF scope parameters to manipulate memory handling behavior.

Successful exploitation may cause the ONVIF management service to crash, resulting in DoS condition that impacts normal device operation.
