Juniper SIRT (JSA) via NVD
Juniper's advisory portal (kb.juniper.net) is a login-walled Salesforce app, so VulniPulse ingests Juniper SIRT (JSA) advisories from NVD, filtered to Juniper's own CNA ([email protected]) — official, machine-readable data with the affected Junos releases in each description. Junos on SRX/MX/EX/QFX and Junos Space are the common targets.

High [CVE-2026-102079] OS command injection vulnerability in the CLI of Juniper Networks Junos OS allows a local, low privileged attacker to take complete control of the device
An OS command injection vulnerability in the CLI of Juniper Networks Junos OS allows a local, low privileged attacker to take complete control of the device. A specific 'request csds' command doesn't sanitize user provided input so that it can be interpreted as a command. This allows unintended command execution with root privileges, which can lead to unauthorized system access or modification. This issue affects Junos OS: - 24.4 versions before 24.4R2-S4; - 25.2 versions before 25.2R2-S1; - 25.4 versions before 25.4R1-S3; This issue does not affect Junos OS releases before 24.4R1.
High [CVE-2026-102081] Missing Release of Memory after Effective Lifetime vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a complete Denial-of-Service (DoS)
A Missing Release of Memory after Effective Lifetime vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a complete Denial-of-Service (DoS). On SRX4000 Series, and SRX5000 Series with SPC3, and MX Series with SPC3, when one or more specific application services like ALGs, IDP/DPI, APPID, SECINTEL, AAMW or AppQoE are configured, a high connections per second churn will cause PFE memory to leak. If the memory is exhausted traffic processing will be impacted. Use the CLI command show security monitoring to monitor the memory utilization of the PFEs on the FPCs. This issue affects Junos OS on SRX Series and MX Series: - 23.4 versions from 23.4R2-S3 before 23.4R2-S7; - 24.2 versions from 24.2R2 before 24.2R2-S3;
