The login flow in Zenitel Connect before 1.11.0 applies per-account lockout on repeated failed login attempts, which allows remote attackers to cause a denial of service (temporary lockout of targeted user accounts from the web interface, repeatable for as long as the attack continues) via repeated failed login requests for a known or guessed username. Intercom call handling is not affected.

CVE-2026-1266265.3 MÉD44.8%
——13The web services listener of Progressive Robot hMailServer 6.3.3 through 6.3.7 counts every failed CardDAV, CalDAV or Autodiscover sign-in from a proxy it trusts - one on the same machine, or one named in WebServicesTrustedProxies, whose X-Forwarded-Proto it believes - against the proxy's own address, which allows a remote unauthenticated attacker who can reach the proxy to have that address banned from the server's mail listeners. The listener, off by default (WebServicesHttpPort and WebServicesHttpsPort 0), signs an account in with HTTP Basic over HTTPS for CardDAV from 6.3.3 and for CalDAV and Outlook Autodiscover from 6.3.4. Behind a TLS-terminating proxy, which the server trusts when it is on the same machine or named in WebServicesTrustedProxies, the listener takes the client's HTTPS from the proxy's X-Forwarded-Proto header, but it does not believe X-Forwarded-For and sees the proxy's address for every client. Each failed sign-in counted towards the auto-ban against that address, so that failed sign-ins through the proxy from anybody, under any user name, reaching MaxInvalidLogonAttempts (3 within 30 minutes by default) wrote an IP range that refused the proxy's address at the SMTP, POP3, IMAP and ManageSieve listeners for AutoBanMinutes (60 by default), and could write it again each time it lapsed. For a proxy on the same machine that address is the loopback address, so that a webmail on that machine, local scripts that submit mail and the other local clients of the mail listeners were shut out; for a proxy at another address that also carries mail, every mail client behind it was. Such a proxy forwarding to the listener's HTTPS port, re-encrypting, was counted against in the same way, and listing it in WebServicesTrustedProxies did not spare it. The auto-ban is on by default and AutoBanNeverBan, which spares an address, is empty by default; the listener itself went on serving the proxy.1dCVE-2026-351615.3 MÉD34.0%
——10Dell PowerScale InsightIQ, versions 5.2.0 through 6.3.0, contains an Overly Restrictive Account Lockout Mechanism vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Denial of service.30dCVE-2026-1058667.5 ALT31.2%
——9Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, an unauthenticated attacker who knows an account email address or username can abuse the account lockout mechanism of a local-authentication collection to prevent that account from signing in. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.30dCVE-2026-539826.5 MÉD26.4%
——8Cap-go Console < 12.28.2 contains a denial-of-service vulnerability in its account deletion flow that allows an attacker to block authentication and onboarding functions by triggering account deletion while a device identifier is linked to the active session. The platform incorrectly associates the deletion state with the device identifier, causing the affected device or browser environment to be redirected to an account-disabled page for approximately 30 days, preventing any account login or registration from that device.21dCVE-2023-43467.5 ALT72.2%
