CVE-2025-59133: Projectopia Custom Role IDOR Vulnerability (7.5 CVSS)

Technical summary

CVE-2025-59133 is an Insecure Direct Object Reference (IDOR) vulnerability affecting Projectopia's custom role implementation (CWE-639). The flaw permits an unauthenticated, remote attacker to enumerate and access resources by directly manipulating object references associated with custom roles. The attack requires no special privileges, no user interaction, and no special network conditions. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) reflects a high-confidence confidentiality breach with no impact on system integrity or availability.

Business impact

Unauthorized disclosure of sensitive project data, customer information, or business intelligence tied to role-based access controls could harm competitive standing, trigger regulatory compliance failures (GDPR, HIPAA, SOC 2), erode customer trust, and create litigation exposure. The impact scope depends on what data Projectopia stores and which roles are targeted by attackers.

Affected systems

Projectopia versions up to and including 5.1.25.2 are vulnerable. Organizations running these versions in production environments face immediate risk. Verify your installed version via the Projectopia dashboard or administrative interface. The vendor and product list is not populated in the advisory data; consult the official Projectopia security bulletin for definitive version and deployment guidance.

Exploitability

This vulnerability is remotely exploitable without authentication. An attacker can craft requests targeting custom role identifiers from outside your network, making exploitation trivial. No KEV entry has been assigned, indicating that while the threat is well-understood, active exploitation in the wild has not yet been formally cataloged by CISA. Nevertheless, the low attack complexity and lack of privilege requirements mean that exploitation risk is high and weaponization is straightforward.

Remediation

Upgrade Projectopia to a patched version released after 5.1.25.2. Consult the official Projectopia release notes and security advisory to confirm the minimum safe version. Until patching is complete, implement network segmentation to restrict Projectopia access to trusted users, monitor for suspicious role-enumeration requests, and audit custom role assignments for unauthorized access patterns.

Patch guidance

Check Projectopia's official security advisory and release notes for the minimum patched version. Test the upgrade in a non-production environment first, paying attention to any breaking changes in the custom role system. Coordinate the deployment during a scheduled maintenance window to avoid disrupting dependent services. After upgrade, validate that custom roles function as expected and that access controls are properly enforced.

Detection guidance

Monitor HTTP/API logs for repeated attempts to access custom role resources with sequential or enumerated identifiers (e.g., /api/roles/1, /api/roles/2, etc.) from unauthenticated sessions. Alert on 400/403 errors that spike in frequency, as they may indicate IDOR probing. Audit Projectopia's access logs for role-based data exfiltration patterns. If available, enable verbose logging for custom role queries and correlate them with user identity.

Why prioritize this

The HIGH CVSS score (7.5) combined with unauthenticated remote exploitability makes this a priority patch. Although not yet on the KEV catalog, the technical simplicity of exploitation and the direct impact on confidentiality demand rapid remediation. Organizations should target this for patching within 72–96 hours, especially if Projectopia holds PII, financial data, or trade secrets.

Risk score, explained

CVSS 7.5 reflects a remote, unauthenticated attack vector (AV:N/PR:N/UI:N) with no prerequisites for successful exploitation, coupled with high confidentiality impact (C:H). The absence of integrity or availability impact prevents a 'critical' rating, but the ease of exploitation and potential for wide-scale data exposure justify the HIGH severity classification.
