{"apiVersion":"1.0","identifier":"CVE-2026-75575","description":"Rocket.Chat exposes the sendForgotPasswordEmail Meteor method without a DDP rate limit, so an unauthenticated caller may invoke it as often as it likes. The method is reachable over DDP and over the HTTP route POST /api/v1/method.callAnon/sendForgotPasswordEmail, and it triggers a password reset message for any address that matches an account. With no DDPRateLimiter rule registered for it, a caller can drive an unbounded volume of reset mail at a chosen address from the deployment-s own mail sender, and can probe addresses at scale: the method answers true for an address with no account and for a successful send, but false when the address belongs to an account that authenticates through an external provider and Accounts_AllowPasswordChangeForOAuthUsers is off, so repeated calls distinguish that class of account. Later versions register a rule permitting ten calls per minute per client address.","publishedAt":"2026-08-25T02:16:51","lastModifiedAt":"2026-08-25T16:17:26","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75575","cvssScore":5.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","epssProbability":0.00231,"riskScore":0.54,"affectedProduct":"Rocket.Chat","affectedVersions":"unknown","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-75575","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-75575","en":"https://www.redsauce.net/en/cves/CVE-2026-75575","fr":"https://www.redsauce.net/fr/cves/CVE-2026-75575","pt":"https://www.redsauce.net/pt/cves/CVE-2026-75575","de":"https://www.redsauce.net/de/cves/CVE-2026-75575","sk":"https://www.redsauce.net/sk/cves/CVE-2026-75575","el":"https://www.redsauce.net/el/cves/CVE-2026-75575"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-75575"}}
