AVideo 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.

CVE-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.3dCVE-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.5dCVE-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.5dCVE-2026-826447.5 ALT18.1%
——5WWBN AVideo (current e01e41ecc and earlier) contains a brute-force rate limiting bypass in enforceRateLimit(), which protects login.json.php and 13 other endpoints. The function stores its attempt counter via a cache layer (ObjectYPT::setCacheGlobal) that silently discards writes for any client identified as a bot by isBot(). Because isBot() treats a missing User-Agent header as a bot by default — and also matches common bot identifiers such as 'curl', 'bot', 'crawler', and 'spider' — the counter never increments for such clients, so the rate limit never fires. An unauthenticated attacker can therefore submit unlimited login attempts (e.g., by omitting the User-Agent header or using curl's default User-Agent), enabling unrestricted password-guessing attacks.5dCVE-2026-826436.5 MED10.4%
——3WWBN AVideo contains an unauthenticated credential submission vulnerability in plugin/Live/api/preauthorize.json.php that accepts credentials over GET without rate limiting. Attackers can submit correct credentials repeatedly to trigger uncapped two-factor confirmation emails and perform sustained password guessing attacks against user accounts.4dCVE-2026-78617—24.8%
——7WatchGuard Dimension's web login endpoint does not enforce effective rate-limiting or account lockout by default allowing a remote attacker to perform automated password guessing against user accounts. If the account lockout setting is enabled, brute-force attempts are blocked after a defined number of failed attempts, but this setting is not enabled by default.9d
