CVE-2026-6645
HighCVSS 7.3Exploitation Probability (EPSS)
Low risk3th percentile - higher than 3% of all known CVEs
Summary
An insecure process execution vulnerability exists in the PaperCut Print Deploy Client for Windows. The application, which operates with high-level system privileges, improperly performs an internal validation check by invoking a secondary system utility without specifying a path.
Risk Assessment
A local attacker with the ability to modify directories in the system's search path could plant a malicious binary, leading to the execution of malicious code with SYSTEM privileges, resulting in full compromise of the affected host.
Recommendation
It is recommended that the application specifies an absolute path to the invoked utility to minimize the risk of unauthorized access to the system.

A vulnerability has been discovered in Tenda CP3 27.5.57.101 in the SystemAsh function of the file Apis/system.c of the Kylin component. Manipulation of the AlarmVoiceURL argument results in OS command injection. The attack can be launched remotely.
- CVE-2026-86060Critical
RouterOS contains an argument-handling flaw in the SSH login path involving usernames that begin with a prohibited character, allowing 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 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable).
- CVE-2026-67276Critical
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-2026-86190Critical
WWBN AVideo contains a broken access control vulnerability in videoViewsInfo endpoints that returns complete user records including password hashes, recovery tokens, and live session identifiers to unauthenticated callers when a hash parameter is provided. Attackers can use the disclosed session identifier to hijack viewer sessions, including administrator accounts, and obtain sensitive personal data for all video viewers.
- CVE-2026-86189Critical
WWBN AVideo contains a path traversal vulnerability in notify.ffmpeg.json.php that allows unauthenticated attackers to write files to arbitrary locations by supplying a caller-chosen path in the avideoRelativePath parameter. Attackers can replay any previously issued ciphertext as a notifyCode token, which is decrypted but never validated, to bypass authentication and write files to the application root and subdirectories.
- CVE-2026-86184Critical
Lara Dashboard before 1.3.0 contains an authentication bypass vulnerability in the screenshot-login route that allows unauthenticated attackers to authenticate as any user by email when APP_ENV is not production. Attackers can request the GET /screenshot-login/{email} endpoint with a registered email address to receive a fully authenticated session, enabling access to user administration, settings, database contents, and arbitrary code execution through the module installer.
- CVE-2026-10196Critical
The Mail Mint – Email Marketing, Newsletter, Email Automation & WooCommerce Emails plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.31.0 via deserialization of untrusted input in the 'handle_form_submission' function. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to execute code on the server. The vulnerability was partially patched in version 1.23.1.
- CVE-2026-86124Critical
AutoAgent contains an unauthenticated remote code execution vulnerability in the TCP server that binds to all interfaces and executes attacker-supplied commands as root. Attackers can connect to the exposed communication port and execute arbitrary bash commands within the container, gaining access to bind-mounted host workspace directories.
- CVE-2026-86121Critical
Cua computer-server versions before 0.3.42 skip authentication when the CONTAINER_NAME environment variable is unset and bind to all interfaces by default, allowing unauthenticated attackers to execute arbitrary commands. Attackers can reach TCP port 8000 to run shell commands via the run_command endpoint, read and write arbitrary files through file operation endpoints, and access interactive PTY shells without authentication.
Original NVD description (English source)
An insecure process execution vulnerability exists in the pc-printer-updater.exe component of the PaperCut Print Deploy Client for Windows. The application, which typically operates with high-level system privileges, attempts to perform an internal validation check by invoking a secondary system utility using an unqualified file reference. Because the application does not specify an absolute path to this utility, it relies on the operating system's default search order to locate the executable. Under specific conditions, a local attacker with the ability to modify directories within the system's search path could plant a malicious binary that mimics the expected utility. This could result in the malicious code being executed with SYSTEM privileges, leading to a full compromise of the affected host.
