CVE-2026-86299

Status: DeferredHigh (8.6)—

A vulnerability was detected in Linksys RE7000 2.0.15. This affects the function platform_event_pingTest of the file /cgi-bin/json.cgi?PingTest of the component PingTest Handler. The manipulation of the argument pingTestIp/pingTestPktSize/pingTestTimes results in os command injection. The attack can be launched remotely. The exploit is now public and may be used.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.
