  Remote Authentication Bypass in Citrix NetScaler ADC and NetScaler Gateway
  Citrix NetScaler ADC and NetScaler Gateway contain an authentication-bypass vulnerability (CWE-288, 'using an alternate path or channel') that an unauthenticated remote threat actor can exploit. The flaw is triggerable when the appliance is configured as an AAA virtual server or as a Gateway, including SSL VPN, ICA Proxy, CVPN, or RDP Proxy deployments, allowing the attacker to bypass authentication without valid credentials. A successful bypass could give an attacker access to VPN-protected or AAA-gated resources as an authenticated user; no CVSS score has been published yet. Organizations running affected NetScaler appliances in these configurations are exposed, and affected version ranges are not specified in the available data, so defenders should consult Citrix advisory AL26-019. The flaw was added to CISA's KEV on 2026-09-09, indicating exploitation in the wild; ransomware use is unknown, no public PoC is known, and EPSS assigns a 3.4% probability of exploitation within 30 days (88th percentile).

  Argument-Injection Flaw in MikroTik RouterOS SSH Login Enables Privilege Escalation
  CVE-2026-86060 is an argument-injection flaw (CWE-88) in MikroTik RouterOS's SSH login path: when a login supplies a username beginning with a prohibited character, the RouterOS login helper mishandles the argument, allowing the trusted RouterOS policy mask to be changed and privileges to be escalated. An unauthenticated attacker only needs the ability to reach the router's SSH service, since exploitation happens during the SSH login process itself. By altering the policy mask the attacker gains elevated rights on the device, and news reports indicate attackers have used this technique — including logins with usernames such as '-2' — as part of chains that take over routers without needing a password. Any RouterOS deployment running versions before the fixes (6.49.21 Long-term, 7.23.4 Long-term, 7.24.2 Stable) with SSH enabled or reachable is affected, with internet-exposed SSH at highest risk. Multiple outlets report the RouterOS flaws are being actively exploited in the wild, although no public proof-of-concept is known and the flaw is not yet in CISA KEV.

  Unauthenticated Kernel Crash and Memory Leak in MikroTik RouterOS btest
  CVE-2026-67277 is a missing-authentication flaw (CWE-306) in the bandwidth-test (btest) service of MikroTik RouterOS: the service accepts a "related" btest connection before the primary session has completed authentication, so an unauthenticated remote client can start an IPv4 UDP bandwidth test. When the test runs with "random-data=false", the sender transmits an uninitialized tail from a kernel packet buffer, leaking a small amount of kernel memory, and a separate unchecked, inverted packet-size interval causes an unsigned integer underflow that produces anomalously large fragmented output capable of restarting the RouterOS kernel. An unauthenticated network attacker therefore gains limited information disclosure and, more significantly, a remote denial of service through repeated router crashes, with no credentials or user interaction required (CVSS 4.0: 8.8 High). Any MikroTik device running an unpatched RouterOS version with the bandwidth-test server enabled and reachable from an untrusted network is affected. No public PoC or CISA KEV listing exists for this CVE and EPSS is low (0.4%), but it is part of the batch of RouterOS fixes in MikroTik advisory AV26-887 that attackers have recently chained to hijack routers, so in-the-wild exploitation of the flaw set is reported.

  SSH RSA Authorized-Key Bypass in MikroTik RouterOS 7.x
  MikroTik RouterOS 7.x fails to compare the complete RSA public key when matching an SSH authentication attempt against an authorized user key, checking the key type and modulus but omitting the exponent. Because RouterOS verifies the signature against the client-supplied key, an attacker who knows the modulus of an authorized RSA key can present a key with exponent 1 and a forged signature and be accepted as that user without possessing the private key. Successful exploitation opens an SSH command channel as the target user, giving the attacker control of the router without a password or key. Only the RouterOS 7.x branch is affected, with fixes released in 7.23.4 (Long-term) and 7.24.2 (Stable). A public proof-of-concept is available and related reporting describes active campaigns hijacking MikroTik routers using chained RouterOS flaws, though this CVE is not in CISA KEV and its 30-day EPSS probability is low (0.2%).

  Unauthenticated Buffer Overflow in Citrix NetScaler ADC and NetScaler Gateway
  CVE-2026-19489 is a vulnerability in Citrix NetScaler ADC and NetScaler Gateway classified as a classic buffer overflow (CWE-120), meaning input is copied into a buffer without adequate size checks; it was disclosed by Citrix alongside CVE-2026-19490, the authentication bypass receiving most of the headline attention. Per the CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N), the flaw is reachable over the network by an unauthenticated remote attacker with no user interaction, though detailed trigger conditions are not spelled out in the CVE description. The scoring (VC:L/VI:L/VA:H, base 8.8 High) indicates the primary impact is to availability — likely crashes or denial of service on the appliance — with low confidentiality and integrity impact. All organizations running NetScaler ADC or NetScaler Gateway 14.1 releases through build 73.32, or 13.1 releases through build 63.21, fall within the affected ranges. There is no evidence of exploitation so far: the issue is not in CISA KEV, has no known public proof-of-concept, and EPSS estimates only a 0.4% probability of exploitation in the next 30 days (32nd percentile).

  Authentication Bypass in Check Point SmartConsole Grants Full Admin Access
  Check Point SmartConsole, the administrative client used to manage Quantum Security Management and Multi-Domain Security Management, contains an authentication bypass (CWE-287) in its login process that allows an unauthenticated remote attacker to obtain an application login token and authenticate with full administrative privileges. Exploitation is possible when the Management Server IP address is reachable from the internet and the configuration does not restrict Trusted Clients. A successful attacker can modify security policies and security configurations, effectively taking control of firewall management. Any organization running an internet-exposed Check Point management server without Trusted Client restrictions is affected, though Check Point reports exploitation has impacted only a very small number of customers. The flaw was added to CISA's KEV on 2026-07-22, is actively exploited, and press reports indicate public proof-of-concept code has been released.

  OS Command Injection in ConfigServer Security & Firewall (CSF) Allows Root RCE
  CVE-2026-65639 is an OS command injection flaw (CWE-78, CVSS 4.0 score 9.5, critical) in the advanced-rule parser of ConfigServer Security & Firewall (CSF), a widely used Linux firewall suite. It is triggered when the parser processes rule data supplied by a configured allow/deny feed: because feed-supplied rule content is not sufficiently validated, an attacker who can control the contents of such a feed (for example by controlling or tampering with the feed source) can inject and execute arbitrary shell commands. Injected commands run as root, so successful exploitation yields full takeover of the host, with high impact to confidentiality, integrity, and availability (the CVSS AT:P metric reflects the precondition that a feed must be configured and attacker-influenced). Affected deployments include versions originally distributed by ConfigServer and versions of the WebPros-maintained fork that contain the vulnerable code; WebPros has fixed the issue in version 16.30, while other independently maintained forks may also be affected. No public proof-of-concept is known, the flaw is not in CISA KEV, and there is no confirmed exploitation in the wild at this time.

  Authenticated Root RCE via Improper Symlink Handling in Plesk
  Plesk, the WebPros hosting control panel, resolves symlinks without verifying their targets before file access (CWE-59, link following), so privileged panel operations can be redirected through an attacker-controlled symlink. The flaw is triggered remotely by an authenticated low-privileged user — for example a tenant account on a shared hosting server — who gets Plesk's privileged file operations to follow a malicious link. A successful attacker executes arbitrary code with root privileges on the hosting server, compromising the control panel, every site it hosts, and the underlying OS. All Plesk deployments are potentially affected, but the specific vulnerable version range is not given in the available data, so operators should consult WebPros advisory AV26-854 for fixed releases. No public PoC, KEV listing, or confirmed in-the-wild exploitation is known, and EPSS estimates only about a 0.5% probability of exploitation within 30 days.

  Potential RCE in Progress Telerik UI for ASP.NET AJAX via dialog parameter tampering
  Progress Telerik UI for ASP.NET AJAX before v2026.3.812 provides insufficient integrity protection (CWE-345) on the dialog request parameters used by the RadEditor file browser, allowing those parameters to be altered. To exploit it, a network attacker must first have obtained certain application encryption key material used to protect the dialog parameters, which drives the high attack complexity; no privileges or user interaction are required. With tampered parameters, the attacker can control which folders the file browser reads from, writes to, and uploads into, enabling arbitrary file uploads (CWE-434) and potentially remote code execution by writing attacker-controlled files into sensitive or web-executable locations. Any web application built with Telerik UI for ASP.NET AJAX in versions prior to 2026.3.812 is affected. Exploitation has not been observed: there is no public proof-of-concept, the flaw is not in the CISA KEV catalog, and EPSS assigns only a 0.2% probability of exploitation within 30 days.
