CVE-2026-79886
HighCVSS 8.2Exploitation Probability (EPSS)
Low risk13th percentile - higher than 13% of all known CVEs
Summary
An unauthenticated buffer overflow vulnerability exists in the PAPI protocol of AOS-8. Successful exploitation could allow an unauthenticated remote attacker to disrupt the availability of the affected service on the controller, with a limited impact to its integrity.
Risk Assessment
An attacker could cause service unavailability on the controller without authentication, potentially interrupting network management. Integrity impact is limited, but the operational disruption may be noticeable.
Recommendation
Update AOS-8 to a version containing the fix and restrict access to the PAPI protocol and controller ports to trusted network segments.

See all- CVE-2026-79875Critical
A vulnerability has been identified in the PAPI protocol of AOS-8 that could potentially allow an unauthenticated adjacent attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to gain administrative access, modify system configurations, and access or manipulate sensitive data.
- CVE-2026-79870Critical
An authentication bypass vulnerability in the PAPI protocol of AOS-8 could allow an unauthenticated adjacent attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to gain administrative access, modify system configurations, access or manipulate sensitive data, and disrupt network operations.
- CVE-2026-79868Critical
Authentication bypass vulnerabilities in the affected interface of AOS-8 could allow an unauthenticated adjacent attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to gain administrative access, modify system configurations, and access or manipulate sensitive data, leading to complete compromise of the affected system.
- CVE-2026-79867Critical
Authentication bypass vulnerabilities in the affected interface of AOS-8 could allow an unauthenticated adjacent attacker to circumvent existing authentication controls and run arbitrary commands on the underlying host. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system leading to complete system compromise.
- CVE-2026-79866Critical
An unauthenticated path traversal vulnerability exists in the PAPI protocol in AOS-8. Successful exploitation of this vulnerability could allow an unauthenticated adjacent attacker to read, modify, and delete files on the underlying operating system.
- CVE-2026-79860Critical
Buffer overflow vulnerabilities exist in an underlying service of AOS-8 that could lead to unauthenticated remote code execution by sending specially crafted packets to UDP port 8211 of the PAPI protocol. Successful exploitation could allow an attacker to execute arbitrary code as a privileged user on the underlying operating system.
- CVE-2026-79859Critical
Buffer overflow vulnerabilities exist in the affected interface of AOS-8 that could lead to unauthenticated remote code execution. Successful exploitation could allow an attacker to execute arbitrary code as a privileged user on the underlying operating system.
- CVE-2026-79858Critical
An unauthenticated SQL injection vulnerability exists in the PAPI protocol in AOS-8. Successful exploitation could allow an unauthenticated remote attacker to obtain and modify sensitive information in the underlying database and to interrupt the normal operation of the affected service.
- CVE-2026-79857Critical
There is a command injection vulnerability in the PAPI protocol (Aruba's access point management protocol) of AOS-8 that could lead to unauthenticated remote code execution by sending specially crafted packets to the affected UDP port. Successful exploitation results in the ability to execute arbitrary code as a privileged user on the underlying operating system.
- CVE-2026-79856Critical
A buffer overflow vulnerability exists in the PAPI protocol of AOS-8 that could allow an unauthenticated remote attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to gain administrative access, modify system configurations, and access or manipulate sensitive data.
