CVE-2025-25202 Vulnerability Summary

CVE-2025-25202: 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.

Assessing the Risk of CVE-2025-25202

Access Complexity Graph

The exploitability of CVE-2025-25202 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2025-25202

No exploitability data is available for CVE-2025-25202.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2025-25202, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2025-25202, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2025-25202 does not compromise confidentiality.
  • Integrity: None
    CVE-2025-25202 does not impact data integrity.
  • Availability: None
    CVE-2025-25202 does not affect system availability.

Exploit Prediction Scoring System (EPSS)

CWE Common Weakness Enumeration

CWE-269

CAPEC Common Attack Pattern Enumeration and Classification

  • Privilege Abuse CAPEC-122 An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.
  • Privilege Escalation CAPEC-233 An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.
  • Restful Privilege Elevation CAPEC-58 An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
