EPSS score0.37%
A NULL Pointer Dereference vulnerability in the routing-policy nexthop-ECMP matcher of Juniper Networks Junos OS and Junos OS Evolved allows a configured eBGP peer to cause a routing-daemon denial of service via a specific BGP packet received while a nexthop-ecmp qualifier is attached to a BGP import policy.CVE-2026-101959juniper networksjunos os+1EPSS score0.25%
A Function Call With Incorrect Variable or Reference as Argument vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause an rpd crash via specifically malformed LSP-ping.CVE-2026-101949juniper networksjunos os+1EPSS score0.45%
A NULL Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated remote BGP neighbor to cause a denial of service via a VPN-flowspec BGP update if it is readvertised and BMP post-policy RIB-out monitoring is configured.CVE-2026-101954juniper networksjunos os+1EPSS score0.49%
An Improper Authentication vulnerability in the J-Web management interface and its NETCONF session handling of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network attacker to obtain root-level device configuration access and take over the device via a reachable J-Web HTTP or HTTPS service when web management is enabled.CVE-2026-101952juniper networksjunos os+1EPSS score0.37%
An Improper Validation of Consistency within Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a configured BGP ISO-VPN peer to cause an rpd crash by sending a specific ISO-VPN update which is then processed by BMP route monitoring or NSR.CVE-2026-103994juniper networksjunos osEPSS score0.43%
A Heap-based Buffer Overflow vulnerability in the VXLAN Gateway Daemon (vgd) of Juniper Networks Junos OS allows a malicious or compromised SDN-controller to cause a complete outage of the OVSDB control plane and possibly remote code execution.CVE-2026-103993juniper networksjunos os+1EPSS score0.24%
An Out-of-bounds Write vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent attacker which sends a specific set of BGP communities to cause a Denial-of-Service (DoS) as rpd crashes when graceful-shutdown sender community is added when attempting to advertise.CVE-2026-102087juniper networksjunos os+1EPSS score0.25%
An Incomplete List of Disallowed Inputs vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).
When in a BGP traffic engineering scenario a specific, valid, optional, non-transitive BGP update is received over an established BGP session, RPD crashes and automatically restarts, which leads to traffic impact until routing has reconverged.

A NULL Pointer Dereference vulnerability in the DNS plugin of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a complete Denial-of-Service (DoS).
When multiple DNS queries are received in a single flow session, where one query matches a Security Intelligence (SecIntel) feed and another query is sent for DNS Domain Generation Algorithm (DGA) analysis, an error in processing logging of these asynchronous tasks can lead to an FPC crash. The exact timing conditions are outside an attacker's direct control.
This issue affects Junos OS on SRX Series:
* All versions before 23.2R2-S7.7;
* from 23.4 before 23.4R2-S8.13;
* from 24.2 before 24.2R2-S5.5;
* from 24.4 before 24.4R2-S4;
* from 25.2 before 25.2R2-S1;
* from 25.4 before 25.4R1-S2.CVE-2026-102085juniper networksjunos os evolvedEPSS score0.29%
An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a limited information disclosure and availability impact to the device.
Due to a wrong initialization, a process which should only be able to communicate internally within the device can be reached over the network via an open port. This leads to a device being inadvertently exposed and increased CPU cycles spent processing ingress packets.
This issue affects Junos OS Evolved:
* All versions before 23.2R2-S7.7-EVO;
* 23.4 versions before 23.4R2-S8.11-EVO;
* 24.2 versions before 24.2R2-S5.6-EVO;
* 24.4 versions before 24.4R2-S4-EVO;
* 25.2 version before 25.2R2-S1-EVO;
* 25.4 versions before 25.4R1-S1-EVO.
Please note that this issue is similar to but not identical CVE-2026-33803.CVE-2026-102084juniper networksjunos osEPSS score0.51%
An Improper Validation of Syntactic Correctness of Input vulnerability in the VPN daemon of Juniper Networks Junos OS on SRX Series allows an authenticated, network-based attacker to take complete control of the device.
If an SRX device configured for AutoDiscovery VPN (ADVPN) receives a message from a peer that contains one or more specifically malformed attributes, this will cause a buffer overflow, which can allow remote code execution and therefore allow an attacker to take complete control of the device. To be able to carry out this attack an attacker must either have acquired the shared secret to impersonate a peer or have compromised an existing one, so this attack is considerably difficult.
This issue affects Junos OS on SRX Series:
* All versions before 23.2R2-S7.7;
* from 23.4 before 23.4R2-S7;
* from 24.2 before 24.2R2-S4;
* from 24.4 before 24.4R2-S3;
* from 25.2 before 25.2R2;
* from 25.4 before 25.4R1-S3.CVE-2026-102083juniper networksjunos osEPSS score0.31%
An Improper Resource Locking vulnerability in the UTM processing of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).
When UTM WebFiltering is configured and the WebFiltering cloud server is unreachable, sustained HTTP traffic load may cause the UTM subsystem to crash and restart, which will lead to a complete service outage until the system has recovered.
When category lookup requests cannot be completed, they accumulate internally. Under high load and specific timing conditions, an invalid internal state can occur during cleanup of pending WebFiltering lookups, resulting in a crash of the UTM process.
This issue applies to both NextGeneration WebFiltering (NGWF) and Enhanced WebFiltering (EWF).
This issue affects Junos OS on SRX Series:
* 23.2 versions from 23.2R2 before 23.2R2-S7.7;
* 23.4 versions from 23.4R2 before 23.4R2-S8.13;
* 24.2 versions before 24.2R2-S5.5;
* 24.4 versions before 24.4R2-S4;
* 25.2 versions before 25.2R2-S1;
* 25.4 versions before 25.4R1-S3, 25.4R2.CVE-2026-102072juniper networksjunos osEPSS score0.41%
