CVE-2026-85102: Improper Certificate Validation in Quantum Security Gateway

Noroxi assessment

Priority: Now (action score 85/100)

CISA has confirmed exploitation in the wild (Sep 22, 2026). Remediation deadline for US federal agencies: Sep 25, 2026.
Probability of exploitation in the next 30 days: 54.1% (FIRST EPSS); higher than 99% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
According to the record, no fixed version is available yet.

Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Root cause

A certificate validation error is silently swallowed instead of terminating the connection. Often, code added for a test environment makes its way into production.
