🚨 CVE-2026-21901
A NULL Pointer Dereference vulnerability in the management daemon (mgd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, high-privileged attacker setting or deactivating a specific SSH configuration parameter to create a Denial of Service (DoS).

A local high-privileged user configuring or deactivating a specific 'system services ssh' configuration parameter can exploit a null pointer dereference in one of the functions used by SSH. The function attempts to dereference a null pointer when accessing certain configuration data, resulting in an mgd process crash and restart. Continued execution of these configuration commands will create a sustained Denial of Service (DoS) condition.

This issue affects:
Junos OS:


* from 22.3 before 22.3R3-S5;
* from 22.4 before 22.4R3-S10;
* from 23.2 before 23.2R2-S7;
* from 23.4 before 23.4R2-S8.




This issue does not affect Junos OS before 22.3R1.



Junos OS Evolved:
* from 22.3R1-EVO before 23.2R2-S7-EVO;
* from 23.4 before 23.4R2-S8-EVO.


This issue does not affect Junos OS Evolved before 22.3R1-EVO.

🚨 CVE-2026-33794
An Improper Check for Unusual or Exceptional Conditions vulnerability in the

advanced forwarding toolkit (evo-aftmand)

of Juniper Networks Junos OS Evolved on PTX Series allows an unauthenticated network-based attacker generating continuous routing updates, resulting in unilist ECMP routes, to crash the

evo-aftmand process on the PFE, leading to a Denial-of-Service (DoS). The conditions required for successful exploitation are based on a sequence of events that are outside an attacker's direct control.

Unified list (unilist) ECMP routes are a specific ECMP behavior where multiple equal-cost routes share a single logical next-hop list entry. The router treats them as one route with multiple next hops and load balances traffic across that unified list. Due to an issue processing unilist ECMP routing updates, internal state corruption may occur, especially in large-scale ECMP unilist deployments, leading to the evo-aftmand process crashing, resulting in an evo-aftmand-bx core. Manual intervention is required to recover by rebooting the system or restarting the FPC.

This issue affects Junos OS Evolved on PTX :


* from 24.4R2-EVO before 24.4R2-S3-EVO;
* from 25.2 before 25.2R2-EVO.

🚨 CVE-2026-60120
Bagisto before 2.4.4 contains a stored cross-site scripting vulnerability via client-side template injection that allows unauthenticated attackers to execute arbitrary JavaScript in administrator browsers by registering a customer account with malicious payload in the first or last name field. The create.blade.php template renders customer name fields without the Vue.js v-pre directive, causing Vue.js to evaluate stored template expressions as live JavaScript when an administrator opens the Create Order page for the affected customer.

🚨 CVE-2026-57021
An Out-of-bounds Write vulnerability in the http-gatekeeper (http-gk) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).

If an SRX Series device is configured for remote-access VPN with pre-logon compliance check, a network-based attacker sending specifically formatted requests can trigger an out of bounds write leading to an http-gk process crash. This crash leads to unavailability of all services depending on the [ system services web-management ] configuration (like J-Web, remote access VPN and firewall authentication) until the process automatically restarts.

This issue affects Junos OS on SRX Series:

🚨 CVE-2026-57022
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on MX with SPC3 and SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).

When an affected device initiates a TCP connection to an attacker-controlled system that responds with a specific packet, this causes a PFE crash and restart, which affects all services until the system has automatically recovered.
This issue can happen among others in the following scenarios: ALG, SSL proxy, UTM, RTLOG, AppQoE probing, AAMW, ICAP, URL filtering.

This issue affects Junos OS on MX Series with SPC3, SRX5k Series with SPC3, SRX1600 Series, SRX2300 Series, SRX4000 Series, and vSRX Series:

🚨 CVE-2026-57024
A Use of Multiple Resources with Duplicate Identifier vulnerability in the IKE daemon (iked) of Juniper Networks Junos OS on MX with SPC3 and SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).



On an MX with SPC3 and SRX devices configured for VPN service, when a large number of VPN negotiations fail a peer index rollover will eventually occur. As a result, new peers are assigned index values that are already in use and the iked process starts to crash repeatedly. This results in failure to establish new VPN connections and rekeying existing ones. To restore service the system must be rebooted.
Please note that the index value can't be monitored, so customers should monitor tunnel up and down events and if a lot of events occur over an extended period of time it becomes likely that this issue occurs.

To be exposed to this issue the system needs to run iked (vs. kmd which is not affected), which can be verified with:
