| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2026-32148 | Insufficient Verification of Data Authenticity vulnerability in hexpm hex (Hex.RemoteConverger module) allows dependency integrity bypass via unverified lockfile checksums. Hex stores checksums for dependencies in the mix.lock file to ensure reproducible and integrity-checked builds. However, Hex.RemoteConverger.verify_resolved/2 never executes checksum verification because the lock data returned by Hex.Utils.lock/1 uses string-based dependency names, while the verification logic compares again | 6b3ad84c-e1a6-4bf7-a703-f496b71e49db | 8.9 | 0.02% | 2026-04-30 | 2026-05-05 |
| CVE-2026-23940 | Uncontrolled Resource Consumption vulnerability in hexpm hexpm/hexpm allows Excessive Allocation. Publishing an oversized package can cause Hex.pm to run out of memory while extracting the uploaded package tarball. This can terminate the affected application instance and result in a denial of service for package publishing and potentially other package-processing functionality. This issue affects hexpm: before 495f01607d3eae4aed7ad09b2f54f31ec7a7df01; hex.pm: before 2026-03-10. | 6b3ad84c-e1a6-4bf7-a703-f496b71e49db | 7.1 | 0.05% | 2026-03-13 | 2026-04-06 |
| CVE-2026-21622 | Insufficient Session Expiration vulnerability in hexpm hexpm/hexpm ('Elixir.Hexpm.Accounts.PasswordReset' module) allows Account Takeover. Password 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. If a user's historical emails are exposed through a data breach (e.g., a leaked mailbox | 6b3ad84c-e1a6-4bf7-a703-f496b71e49db | 9.5 | 0.05% | 2026-03-05 | 2026-04-06 |
| CVE-2026-21621 | Incorrect Authorization vulnerability in hexpm hexpm/hexpm ('Elixir.HexpmWeb.API.OAuthController' module) allows Privilege Escalation. An API key created with read-only permissions (domain: "api", resource: "read") can be escalated to full write access under specific conditions. When exchanging a read-only API key via the OAuth client_credentials grant, the resource qualifier is ignored. The resulting JWT receives the broad "api" scope instead of the expected "api:read" scope. This token is th | 6b3ad84c-e1a6-4bf7-a703-f496b71e49db | 7.0 | 0.03% | 2026-03-05 | 2026-04-06 |
| CVE-2026-21619 | Uncontrolled Resource Consumption, Deserialization of Untrusted Data vulnerability in hexpm hex_core (hex_api modules), hexpm hex (mix_hex_api modules), erlang rebar3 (r3_hex_api modules) allows Object Injection, Excessive Allocation. This vulnerability is associated with program files src/hex_api.erl, src/mix_hex_api.erl, apps/rebar/src/vendored/r3_hex_api.erl and program routines hex_core:request/4, mix_hex_api:request/4, r3_hex_api:request/4. This issue affects hex_core: from 0.1.0 before 0. | 6b3ad84c-e1a6-4bf7-a703-f496b71e49db | 2.0 | 0.06% | 2026-02-27 | 2026-04-06 |
| CVE-2026-23939 | Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in hexpm hexpm/hexpm ('Elixir.Hexpm.Store.Local' module) allows Relative Path Traversal. This vulnerability is associated with program files lib/hexpm/store/local.ex and program routines 'Elixir.Hexpm.Store.Local':get/3, 'Elixir.Hexpm.Store.Local':put/4, 'Elixir.Hexpm.Store.Local':delete/2, 'Elixir.Hexpm.Store.Local':delete_many/2.
