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."}],"problemTypes":[{"descriptions":[{"lang":"en","cweId":"CWE-307","description":"Improper Restriction of Excessive Authentication Attempts","type":"CWE"}]},{"descriptions":[{"lang":"en","cweId":"CWE-204","description":"Observable Response Discrepancy","type":"CWE"}]}],"affected":[{"vendor":"RocketChat","product":"Rocket.Chat","repo":"https://github.com/RocketChat/Rocket.Chat","packageURL":"pkg:github/RocketChat/Rocket.Chat","defaultStatus":"unaffected","versions":[{"version":"0","lessThan":"7.10.15","status":"affected","versionType":"semver"},{"version":"8.0.0","lessThan":"8.1.8","status":"affected","versionType":"semver"},{"version":"8.2.0","lessThan":"8.2.8","status":"affected","versionType":"semver"},{"version":"8.3.0","lessThan":"8.3.8","status":"affected","versionType":"semver"},{"version":"8.4.0","lessThan":"8.4.6","status":"affected","versionType":"semver"},{"version":"8.5.0","lessThan":"8.5.3","status":"affected","versionType":"semver"},{"version":"8.6.0","lessThan":"8.6.2","status":"affected","versionType":"semver"},{"version":"8.7.0","lessThan":"8.7.2","status":"affected","versionType":"semver"},{"version":"8.8.0-rc.0","lessThan":"8.8.0","status":"affected","versionType":"semver"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","versionEndExcluding":"7.10.15"},{"vulnerable":true,"criteria":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","versionEndExcluding":"8.1.8","versionStartIncluding":"8.0.0"},{"vulnerable":true,"criteria":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","versionEndExcluding":"8.2.8","versionStartIncluding":"8.2.0"},{"vulnerable":true,"criteria":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","versionEndExcluding":"8.3.8","versionStartIncluding":"8.3.0"},{"vulnerable":true,"criteria":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","versionEndExcluding":"8.4.6","versionStartIncluding":"8.4.0"},{"vulnerable":true,"criteria":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","versionEndExcluding":"8.5.3","versionStartIncluding":"8.5.0"},{"vulnerable":true,"criteria":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","versionEndExcluding":"8.6.2","versionStartIncluding":"8.6.0"},{"vulnerable":true,"criteria":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","versionEndExcluding":"8.7.2","versionStartIncluding":"8.7.0"},{"vulnerable":true,"criteria":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","versionEndExcluding":"8.8.0","versionStartIncluding":"8.8.0-rc.0"}]}]}],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","baseScore":6.9,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"LOW","vulnIntegrityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE"}},{"format":"CVSS","cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"}}],"references":[{"url":"https://github.com/RocketChat/Rocket.Chat/security/advisories/GHSA-7c6v-m68v-v73r","name":"GitHub Security Advisory (GHSA-7c6v-m68v-v73r)","tags":["vendor-advisory"]},{"url":"https://github.com/RocketChat/Rocket.Chat","tags":["product"]},{"url":"https://github.com/RocketChat/Rocket.Chat/commit/3a61c3afe","tags":["patch"]},{"name":"VulnCheck Advisory: Rocket.Chat Missing DDP Rate Limit on the sendForgotPasswordEmail Meteor Method","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/rocket-chat-missing-ddp-rate-limit-on-the-sendforgotpasswordemail-meteor-method"}],"credits":[{"lang":"en","value":"nedlir","type":"finder"}],"x_generator":{"engine":"vulncheck-endgame"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-25T15:25:37.838804Z","id":"CVE-2026-75575","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-25T15:25:46.054Z"}}]}}
