CVE-2025-68113 6.5 MEDIUM 6 Writeups EPSS 0.00

ALTCHA is privacy-first software for captcha and bot protection. A cryptographic semantic binding flaw in ALTCHA libraries allows challenge payload splicing, which may enable replay attacks. The HMAC signature does not unambiguously bind challenge parameters to the nonce, allowing an attacker to reinterpret a valid proof-of-work submission with a modified expiration value. This may allow previously solved challenges to be reused beyond their intended lifetime, depending on server-side replay handling and deployment assumptions. The vulnerability primarily impacts abuse-prevention mechanisms such as rate limiting and bot mitigation. It does not directly affect data confidentiality or integrity. This issue has been addressed by enforcing explicit semantic separation between challenge parameters and the nonce during HMAC computation. Users are advised to upgrade to patched versions, which include version 1.0.0 of the altcha Golang package, version 1.0.0 of the altcha Rubygem, version 1.0.0 of the altcha pip package, version 1.0.0 of the altcha Erlang package, version 1.4.1 of the altcha-lib npm package, version 1.3.1 of the altcha-org/altcha Composer package, and version 1.3.0 of the org.altcha:altcha Maven package. As a mitigation, implementations may append a delimiter to the end of the `salt` value prior to HMAC computation (for example, `<salt>?expires=<time>&`). This prevents ambiguity between parameters and the nonce and is backward-compatible with existing implementations, as the delimiter is treated as a standard URL parameter separator.

CWE-772 May 28, 2025

CVE-2025-32782 5.3 MEDIUM 1 Writeup EPSS 0.00

Ash Authentication provides authentication for the Ash framework. The confirmation flow for account creation currently uses a GET request triggered by clicking a link sent via email. Some email clients and security tools (e.g., Outlook, virus scanners, and email previewers) may automatically follow these links, unintentionally confirming the account. This allows an attacker to register an account using another user’s email and potentially have it auto-confirmed by the victim’s email client. This does not allow attackers to take over or access existing accounts or private data. It is limited to account confirmation of new accounts only. This vulnerability is fixed in 4.7.0.

CWE-306 Apr 15, 2025

CVE-2025-25202 6.5 MEDIUM 1 Writeup EPSS 0.00

Ash Authentication is an authentication framework for Elixir applications. Applications which have been bootstrapped by the igniter installer present since AshAuthentication v4.1.0 and who have used the magic link strategy _or_ are manually revoking tokens are affected by revoked tokens being allowed to verify as valid. Unless one hase implemented any kind of custom token revocation feature in your application, then one will not be affected. The impact here for users using builtin functionality is that magic link tokens are reusable until they expire. With that said, magic link tokens are only valid for 10 minutes, so the surface area for abuse is extremely low here. The flaw is patched in version 4.4.9. Additionally a compile time warning is shown to users with remediation instructions if they upgrade. 4.4.9 ships with an upgrader, so those who use `mix igniter.upgrade ash_authentication` will have the necessary patch applied. Otherwise, one may run the upgrader manually as described in the error message. As a workaround, delete the generated `:revoked?` generic action in the token resource. This will cause it to use the one internal to Ash Authentication which has always been correct. Alternatively, manually make the changes that are included in the patch.

CWE-269 Feb 11, 2025

CVE-2025-1211 6.5 MEDIUM 1 Writeup EPSS 0.00

Versions of the package hackney before 1.21.0 are vulnerable to Server-side Request Forgery (SSRF) due to improper parsing of URLs by URI built-in module and hackey. Given the URL http://[email protected]/, the URI function will parse and see the host as 127.0.0.1 (which is correct), and hackney will refer the host as 127.2.2.2/. This vulnerability can be exploited when users rely on the URL function for host checking.

CWE-918 Feb 11, 2025

CVE-2024-51988 6.5 MEDIUM EPSS 0.00

RabbitMQ is a feature rich, multi-protocol messaging and streaming broker. In affected versions queue deletion via the HTTP API was not verifying the `configure` permission of the user. Users who had all of the following: 1. Valid credentials, 2. Some permissions for the target virtual host & 3. HTTP API access. could delete queues it had no (deletion) permissions for. This issue has been addressed in version 3.12.11 of the open source rabbitMQ release and in versions 1.5.2, 3.13.0, and 4.0.0 of the tanzu release. Users are advised to upgrade. Users unable to upgrade may disable management plugin and use, for example, Prometheus and Grafana for monitoring.

CVE-2024-49756 5.3 MEDIUM 1 Writeup EPSS 0.00

AshPostgres is the PostgreSQL data layer for Ash Framework. Starting in version 2.0.0 and prior to version 2.4.10, in certain very specific situations, it was possible for the policies of an update action to be skipped. This occurred only on "empty" update actions (no changing fields), and would allow their hooks (side effects) to be performed when they should not have been. Note that this does not allow reading new data that the user should not have had access to, only triggering a side effect a user should not have been able to trigger. To be vulnerable, an affected user must have an update action that is on a resource with no attributes containing an "update default" (updated_at timestamp, for example); can be performed atomically; does not have `require_atomic? false`; has at least one authorizer (typically `Ash.Policy.Authorizer`); and has at least one `change` (on the resource's `changes` block or in the action itself). This is where the side-effects would be performed when they should not have been. This problem has been patched in `2.4.10` of `ash_postgres`. Several workarounds are available. Potentially affected users may determine that none of their actions are vulnerable using a script the maintainers provide in the GitHub Security Advisory, add `require_atomic? false` to any potentially affected update action, replace any usage of `Ash.update` with `Ash.bulk_update` for an affected action, and/or add an update timestamp to their action.

CVE-2024-31209 5.3 MEDIUM 1 Writeup EPSS 0.00

oidcc is the OpenID Connect client library for Erlang. Denial of Service (DoS) by Atom exhaustion is possible by calling `oidcc_provider_configuration_worker:get_provider_configuration/1` or `oidcc_provider_configuration_worker:get_jwks/1`. This issue has been patched in version(s)`3.1.2` & `3.2.0-beta.3`.

CVE-2024-25718 9.8 CRITICAL 2 Writeups EPSS 0.00

In the Samly package before 1.4.0 for Elixir, Samly.State.Store.get_assertion/3 can return an expired session, which interferes with access control because Samly.AuthHandler uses a cached session and does not replace it, even after expiry.

CVE-2023-5588 2.6 LOW 1 Writeup EPSS 0.01

A vulnerability was found in kphrx pleroma. It has been classified as problematic. This affects the function Pleroma.Emoji.Pack of the file lib/pleroma/emoji/pack.ex. The manipulation of the argument name leads to path traversal. The complexity of an attack is rather high. The exploitability is told to be difficult. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The patch is named 2c795094535537a8607cc0d3b7f076a609636f40. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-242187.

CVE-2023-45312 8.8 HIGH EPSS 0.03

CWE-1188 Oct 10, 2023

CVE-2023-42446 6.5 MEDIUM EPSS 0.00

Pow is a authentication and user management solution for Phoenix and Plug-based apps. Starting in version 1.0.14 and prior to version 1.0.34, use of `Pow.Store.Backend.MnesiaCache` is susceptible to session hijacking as expired keys are not being invalidated correctly on startup. A session may expire when all `Pow.Store.Backend.MnesiaCache` instances have been shut down for a period that is longer than a session's remaining TTL. Version 1.0.34 contains a patch for this issue. As a workaround, expired keys, including all expired sessions, can be manually invalidated.

CWE-298 Sep 18, 2023

CVE-2023-35174 8.6 HIGH 1 Writeup EPSS 0.00

Livebook is a web application for writing interactive and collaborative code notebooks. On Windows, it is possible to open a `livebook://` link from a browser which opens Livebook Desktop and triggers arbitrary code execution on victim's machine. Any user using Livebook Desktop on Windows is potentially vulnerable to arbitrary code execution when they expect Livebook to be opened from browser. This vulnerability has been fixed in version 0.8.2 and 0.9.3.
