An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-75575 in the wild and no public exploit code.\n\nAffected product: RocketChat Rocket.Chat. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-75575/ (Markdown: https://insights.sbomify.com/CVE-2026-75575/index.md)","id":"CVE-2026-75575","markdown":"https://insights.sbomify.com/CVE-2026-75575/index.md","name":"CVE-2026-75575","record":{"aliases":["GHSA-7c6v-m68v-v73r","GHSA-jfh6-w7r2-rj74"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Rocket.Chat","requires_auth":"none","summary":"Unauthenticated attackers can spam password reset emails and enumerate OAuth users due to missing rate limits on the sendForgotPasswordEmail method.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"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","version":"4.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"},{"id":"CWE-204","name":"Observable Response Discrepancy"}],"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Rocket.Chat Missing DDP Rate Limit on the sendForgotPasswordEmail Meteor Method","id":"CVE-2026-75575","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"keeper.sh Calendar version prior to 2.18.14 SSRF Guard Bypass via DNS Rebinding","id":"CVE-2026-75583"},"packages":[],"prev":{"headline":"Grav before 4.2.2 Remote Code Execution via Email Twig","id":"CVE-2026-75574"},"products":["Rocket.Chat"],"published":"2026-08-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-29","vendors":["RocketChat"]},"summary":"Unauthenticated attackers can spam password reset emails and enumerate OAuth users due to missing rate limits on the sendForgotPasswordEmail method.","url":"https://insights.sbomify.com/CVE-2026-75575/"}
