CVE-2026-31874 Vulnerability Summary

CVE-2026-31874: Taskosaur is an open source project management platform with conversational AI for task execution in-app. In 1.0.0, the application does not properly validate or restrict the role parameter during the user registration process. An attacker can manually modify the request payload and assign themselves elevated privileges. Because the backend does not enforce role assignment restrictions or ignore client-supplied role parameters, the server accepts the manipulated value and creates the account with SUPER_ADMIN privileges. This allows any unauthenticated attacker to register a fully privileged administrative account.

Assessing the Risk of CVE-2026-31874

Access Complexity Graph

The exploitability of CVE-2026-31874 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-2026-31874

With low attack complexity and no required privileges, CVE-2026-31874 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.

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-2026-31874, 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-2026-31874, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: High
    Exploiting CVE-2026-31874 can result in unauthorized access to sensitive data, severely compromising data privacy.
  • Integrity: High
    CVE-2026-31874 could allow unauthorized modifications to data, potentially affecting system reliability and trust.
  • Availability: High
    CVE-2026-31874 can disrupt system operations, potentially causing complete denial of service (DoS).
