CVE-2026-102795: Apache Traffic Server: SNI to Host header matching policy is not properly enforced

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.28% (FIRST EPSS).
  • 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.
  • Fixed version: Apache Software Foundation Apache Traffic Server 9.2.15.
  • Severity is disputed: the assigning authority (CNA) scores it 9.3, NVD 7.0.

Low priority for now. Upgrade to Apache Software Foundation Apache Traffic Server 9.2.15 or later.
