CVE-2026-86060

MikroTik RouterOS contains an argument-handling flaw in the SSH login path. An unauthenticated attacker can supply a username beginning with a prohibited character to reach the RouterOS login helper and modify the trusted policy mask , achieving privilege escalation . The vulnerability is rated C...

CVE-2026-67281 Unauthenticated file read in Mikrotik RouterOS

RouterOS WebFig contains an unauthenticated file-read vulnerability in the /jsproxy path where a newly allocated session retains a stale uninitialized principal pointer used for file authorization. An unauthenticated attacker can prepare the allocator so that the file-serving path dereferences th...

EUVD-2026-72026

MikroTik RouterOS accepts malformed RSA/PKCS1 v1.5 signatures during X.509 validation. Because its trust store includes an e=3 root CA, an attacker controlling or redirecting an outbound RouterOS TLS connection can use the root’s public certificate - without its private key - to forge a trusted...

CVE-2026-67279 SSH Pre-Authentication Rekey State Bypass in MikroTik RouterOS

RouterOS SSH enters the connection protocol after a client-requested rekey even though user authentication was never attempted, allowing an unauthenticated client to open a session channel and send an exec request. On affected builds the server dispatches the command, enabling unauthenticated...

CVE-2026-67278 TLS server impersonation possible in Mikrotik RouterOS

MikroTik RouterOS accepts malformed RSA/PKCS1 v1.5 signatures across RSA-based services, including TLS/X.509 certificate validation and SSH host-key authentication. Because its trust store includes an e=3 root CA, an attacker controlling or redirecting an outbound RouterOS TLS connection can use...

CVE-2026-67278

MikroTik RouterOS accepts malformed RSA/PKCS#1 v1.5 signatures during X.509 validation. Because its trust store includes a root CA with e=3 , an attacker who controls or redirects an outbound TLS connection can use the root's public certificate—without its private key—to forge a trusted intermedi...

CVE-2026-67279

MikroTik RouterOS is affected by a SSH pre-authentication rekey state bypass (CVE-2026-67279). The root cause is that the SSH service enters the connection protocol after a client-requested rekey even though user authentication was never attempted, allowing an unauthenticated remote client to ope...

CVE-2026-67277

MikroTik RouterOS btest service is vulnerable to unauthenticated kernel memory disclosure and denial of service . An unauthenticated attacker can exploit a race condition where a "related" btest connection is accepted before primary session authentication completes, then start an IPv4 UDP test. W...

CVE-2026-67277 Kernel memory disclosure and denial of service in MikroTik RouterOS btest service

RouterOS accepts a "related" btest connection before the corresponding primary session has completed authentication. An unauthenticated client can use this state to start an IPv4 UDP test. With "random-data=false", the sender transmits an uninitialized tail from a kernel packet buffer. A separate...

With "random-data=false", the sender transmits an uninitialized tail from a kernel packet buffer. A separate...

CVE-2026-67276 SSH user impersonation possible in Mikrotik RouterOS

RouterOS does not compare the complete RSA public key when matching an SSH authentication request to an authorized user key, checking the key type and modulus but omitting the exponent. Because signature verification uses the client-supplied key, an attacker knowing an authorized RSA modulus can...

CVE-2026-67276 SSH user impersonation possible in Mikrotik RouterOS

RouterOS does not compare the complete RSA public key when matching an SSH authentication request to an authorized user key, checking the key type and modulus but omitting the exponent. Because signature verification uses the client-supplied key, an attacker knowing an authorized RSA modulus can...

CVE-2026-67276

MikroTik RouterOS is vulnerable to an SSH public-key authentication bypass (CWE-347). The server matches a presented public-key blob to an authorized key by key type and modulus only, omitting the exponent , and performs signature verification using the client-supplied key . An attacker who knows...

PT-2026-86453

MikroTik RouterOS accepts malformed RSA/PKCS1 v1.5 signatures during X.509 validation. Because its trust store includes an e=3 root CA, an attacker controlling or redirecting an outbound RouterOS TLS connection can use the root’s public certificate - without its private key - to forge a trusted...
