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-2026-21622 in the wild and no public exploit code.\n\nAffected product: hexpm hex.pm. 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-2026-21622/ (Markdown: https://insights.sbomify.com/CVE-2026-21622/index.md)","id":"CVE-2026-21622","markdown":"https://insights.sbomify.com/CVE-2026-21622/index.md","name":"CVE-2026-21622","record":{"aliases":["EEF-CVE-2026-21622","GHSA-6r94-pvwf-mxqm"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Hex package manager","requires_auth":"none","summary":"Attackers can take over accounts by using non-expiring password reset tokens found in leaked email archives.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"EEF","cpe":[{"product":"hexpm","vendor":"hex"}],"cvss":{"score":9.5,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:H/SI:H/SA:L","version":"4.0"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"Insufficient Session Expiration vulnerability in hexpm hexpm/hexpm ('Elixir.Hexpm.Accounts.PasswordReset' module) allows Account Takeover.\n\nPassword reset tokens generated via the \"Reset your password\" flow do not expire. When a user requests a password reset, Hex sends an email containing a reset link with a token. This token remains valid indefinitely until used. There is no time-based expiration enforced.\n\nIf a user's historical emails are exposed through a data breach (e.g., a leaked mailbox archive), any unused password reset email contained in that dataset could be used by an attacker to reset the victim's password. The attacker does not need current access to the victim's email account, only access to a previously leaked copy of the reset email.\n\nThis vulnerability is associated with program files lib/hexpm/accounts/password_reset.ex and program routines 'Elixir.Hexpm.Accounts.PasswordReset':can_reset?/3.\n\nThis issue affects hexpm: from 617e44c71f1dd9043870205f371d375c5c4d886d before bb0e42091995945deef10556f58d046a52eb7884.","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":"Password Reset Tokens Do Not Expire","id":"CVE-2026-21622","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Extension - stackideas.com - Persistent XSS in EasyDiscuss component 1.0.0-5.0.15 for Joomla","id":"CVE-2026-21623"},"packages":[],"prev":{"headline":"Improper Scope Enforcement in OAuth client_credentials Flow Allows Read-Only API Key to Escalate to Full Access","id":"CVE-2026-21621"},"products":["hex.pm","hexpm"],"published":"2026-03-05","related":[{"cvss_score":8.5,"headline":"Cross-site scripting (XSS) in OAuth Device Authorization screen","id":"CVE-2026-21618","kev_date_added":null,"published":"2026-01-19"},{"cvss_score":7.1,"headline":"Denial of Service via Oversized Package Upload","id":"CVE-2026-23940","kev_date_added":null,"published":"2026-03-13"},{"cvss_score":7,"headline":"Improper Scope Enforcement in OAuth client_credentials Flow Allows Read-Only API Key to Escalate to Full Access","id":"CVE-2026-21621","kev_date_added":null,"published":"2026-03-05"},{"cvss_score":6.9,"headline":"Path Traversal in Local File Store Backend","id":"CVE-2026-23939","kev_date_added":null,"published":"2026-02-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"total"},"state":"PUBLISHED","updated":"2026-04-21","vendors":["hexpm"]},"summary":"Attackers can take over accounts by using non-expiring password reset tokens found in leaked email archives.","url":"https://insights.sbomify.com/CVE-2026-21622/"}
