CVE-2026-205144.4 MED—
——0In Audio HAL, there is a possible information disclosure due to a missing permission check. This could lead to local information disclosure if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS11087632; Issue ID: MSV-8244.22hCVE-2026-20512——
——0In Audio HAL, there is a possible escalation of privilege due to improper input validation. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS11087540; Issue ID: MSV-8246.5hCVE-2026-861866.5 MED7.6%
——2AVideo API fails to enforce rate limits when clients send a bot User-Agent header, allowing attackers to bypass all eight protected operations including login brute-force protection. Attackers can send requests with a bot User-Agent to disable rate limiting and perform unlimited password guessing attempts against any account from a single IP address.3dCVE-2026-85237—22.4%
——7A vulnerability in MISP's email-based one-time password (OTP) authentication flow allowed an attacker to perform an unrestricted number of OTP verification attempts.
The email_otp() endpoint did not apply brute-force protection when validating submitted OTP values. An attacker who had reached the OTP verification stage, for example after successfully providing a user's primary authentication credentials, could repeatedly submit candidate OTP values while the same OTP remained valid. This significantly increased the feasibility of guessing the OTP and bypassing the additional authentication factor, potentially resulting in unauthorized access to the affected user's account.
The issue was exacerbated by the fact that the OTP is associated with the user rather than with an individual pending login session, allowing multiple concurrent sessions to attempt guesses against the same valid OTP.
The patch integrates the existing MISP brute-force protection mechanism into the email OTP flow. Failed OTP attempts are now counted against the user, further attempts are rejected once the configured threshold is reached, and the active OTP is invalidated when the attempt budget is exhausted. Blocklisted users are also prevented from requesting the generation of a fresh OTP. In addition, OTP comparison now uses hash_equals() and validates that the submitted value is a string.5dCVE-2026-16675—1.1%
——0A privilege escalation security issue exists within FactoryTalk® Activation Manager. The security issue stems from custom actions in the installer that spawn visible console windows running with SYSTEM privileges during installation or repair operations. An authenticated attacker with Windows credentials could hijack these console windows to obtain a SYSTEM-level command prompt, allowing full access to all files, processes, and system resources.7dCVE-2026-13348—23.5%
——7CWE-307: Improper Restriction of Excessive Authentication Attempts vulnerability exists that could allow an attacker to gain unauthorized access to a user account by performing an arbitrary number of authentication attempts when redirect handling is disabled.7d
