| CVE-2026-67279 | 1 Mikrotik | 1 Routeros | 2026-09-05 | N/A |
| 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 creation, overwrite, and reconstruction of files in the RouterOS managed file namespace, including support files containing configuration and diagnostic data.This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable) | ||||
| CVE-2026-67278 | 1 Mikrotik | 1 Routeros | 2026-09-05 | N/A |
| MikroTik RouterOS accepts malformed RSA/PKCS#1 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 intermediate and issue certificates for arbitrary hostnames, enabling TLS server impersonation. This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable) | ||||
| CVE-2026-67277 | 1 Mikrotik | 1 Routeros | 2026-09-05 | N/A |
| 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 unchecked, inverted packet-size interval causes unsigned integer underflow, anomalously large fragmented output, and can restart the RouterOS kernel. This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable) | ||||
| CVE-2026-67276 | 1 Mikrotik | 1 Routeros | 2026-09-05 | N/A |
| 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 supply a key with exponent one, forge a valid signature, and open an SSH command channel as the target user without the private key.This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable) | ||||
| CVE-2026-86206 | 1 N-able | 1 N-central | 2026-09-05 | N/A |
| A vulnerability in the N-central internal API access control filter allows unauthorised access to internal APIs. This is fixed in N-central 2026.3 HF3 and 2026.4 | ||||
| CVE-2026-86115 | 2 Sim, Simstudioai | 2 Sim, Sim | 2026-09-05 | 5 Medium |
| Sim before 0.8.14 classifies tool requests as internal based on URL prefix matching without scheme normalization, skipping SSRF validation and minting internal authentication tokens. Authenticated workflow authors can bypass external URL validation by supplying paths starting with /api/ in HTTP blocks to reach internal-only endpoints like POST /api/function/execute. | ||||
| CVE-2026-86060 | 1 Mikrotik | 1 Routeros | 2026-09-05 | N/A |
| RouterOS contains an argument-handling flaw in the SSH login path involving usernames that begin with a prohibited character, allowing for the trusted RouterOS policy mask to be changed, leading to privilege escalation. Exploitation requires an unauthenticated SSH session to reach the RouterOS login helper.This issue was fixed in versions: 6.49.21 (Lont-term), 7.23.4 (Lont-term) and 7.24.2 (Stable) | ||||
| CVE-2026-67281 | 1 Mikrotik | 1 Routeros | 2026-09-05 | N/A |
| 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 this pointer with sufficient rights, then supply parent-directory components in an encrypted URI to escape the WebFig file namespace and disclose root-owned files, including configuration stores containing credentials.This issue was fixed in versions: 6.49.21 (Lont-term), 7.23.4 (Lont-term) and 7.24.2 (Stable) | ||||
| CVE-2026-86207 | 2026-09-05 | N/A | ||

| CVE-2026-18238 | 2026-09-05 | 5 Medium | ||
| The rpcap client code that processes a RPCAP_MSG_PACKET message received from the server incorrectly validates its headers. A malicious server can send a crafted message and cause the client to treat up to 20 bytes of the client process memory beyond the end of the buffer as if it was a part of the captured packet. | ||||
| CVE-2026-18313 | 2026-09-05 | 4.3 Medium | ||
| rpcapd can allocate up to 65536 bytes per each RPCAP_MSG_UPDATEFILTER_REQ or RPCAP_MSG_STARTCAP_REQ message received from the client, but it never frees the memory, so it leaks memory even under normal use. A malicious client can cause the server to leak memory substantially faster. | ||||
| CVE-2026-6554 | 2026-09-05 | 5.5 Medium | ||
| libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations. In particular uncommon use cases a crafted filter program can cause the interpreter to loop infinitely. | ||||
| CVE-2026-6244 | 2026-09-05 | 5.5 Medium | ||
| libpcap BPF interpreter for the 'div #k' and 'mod #k' ALU instructions does not check whether the immediate value is zero. In particular uncommon use cases a crafted filter program can cause a division by zero. | ||||
| CVE-2026-31911 | 2026-09-05 | 5.5 Medium | ||
| libpcap BPF interpreter calls abort() if it encounters a BPF instruction that has an invalid opcode. In particular uncommon use cases a crafted filter program can terminate the OS process. | ||||
| CVE-2026-31912 | 2026-09-05 | 5.5 Medium | ||
| libpcap BPF interpreter detects neither reaching the end of the filter program buffer due to lack of a return instruction nor executing a jump instruction with an offset that translates to a pointer outside of the buffer. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading the OS process memory in the 32GiB around the buffer on 64-bit architectures and in the entire address space on 32-bit architectures. | ||||
| CVE-2026-0799 | 2026-09-05 | 8.7 High | ||
| In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading and writing the OS process memory in the 16GiB starting at the current stack frame on 64-bit architectures and in the entire address space on 32-bit architectures. | ||||
| CVE-2026-86193 | 1 Getgrav | 2 Grav, Grav-plugin-api | 2026-09-05 | N/A |
| grav-plugin-api before 1.0.20 fails to validate group-inherited super permissions in user-management guards, allowing non-super user managers to modify super-admin accounts. Attackers with api.access and api.users.write can patch password fields on group-super accounts to gain full administrative control. | ||||
| CVE-2026-82752 | 1 Ash-project | 1 Ash | 2026-09-05 | N/A |
| Improper Validation of Specified Quantity in Input vulnerability in ash-project ash allows an attacker to store a value of arbitrary size in an attribute whose length constraint should bound it. Ash measures string length with Elixir's String.length/1, which counts Unicode graphemes, in the max_length and min_length constraints of Ash.Type.String (apply_constraints/2 in lib/ash/type/string.ex), in Ash.Resource.Validation.StringLength, and in the string_length expression function. A grapheme carries an unbounded number of combining marks, so a base character followed by a million combining acute accents is one grapheme and megabytes of data, and satisfies max_length: 2. Where the data layer imposes no independent limit (ETS, Mnesia, or a Postgres text column) the whole value is persisted, so an attacker can write an entire request body into an attribute declared with a small maximum and grow storage without bound. The counting unit also disagrees with the storage layer, which counts codepoints rather than graphemes, so a value accepted by the constraint can still be rejected or truncated by the column. A Postgres varchar(n) column bounds the value itself and is not exposed. This issue affects ash: from 0.10.0 before 3.33.0. | ||||
| CVE-2026-78327 | 2026-09-05 | 9.1 Critical | ||
| An Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in the SonicWall Network Security Manager (NSM) On-Prem Management interface allows an authenticated attacker with SuperAdmin privileges to inject arbitrary commands that are executed on the underlying host, resulting in remote code execution. | ||||
| CVE-2026-86194 | 1 Getgrav | 2 Grav, Grav-plugin-form | 2026-09-05 | N/A |
| Grav Form Plugin before 9.1.22 fails to verify page authorization when resolving forms by name across pages, allowing anonymous visitors to execute form actions defined on login-restricted or unpublished pages. Attackers can POST to any public page with a restricted form's name to trigger save, upload, email, or call actions without authentication. | ||||
