Technical Analysis
CVE-2026-35660 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.1.
A proof-of-concept (PoC) exploit exists for CVE-2026-35660. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
