Security readout for executives and security teams
Plain-English summary
CVE-2026-28226 affects Phishing Club before version 1.30.2. A logged-in user could abuse a recipient-list sorting parameter to inject database logic. The main business concern is potential unauthorized data exposure from the application database. The issue is patched in 1.30.2.
Executive priority
Treat as a timely patching item, especially for exposed or multi-user deployments. It is not currently evidenced as actively exploited, but the potential for confidential data exposure justifies prioritizing upgrade during the next security maintenance window.
Technical view
The GetOrphaned recipient listing endpoint builds a raw SQL ORDER BY clause using user-controlled sortBy input. Unknown values were passed through RemapOrderBy(), allowing authenticated blind SQL injection. CVSS 3.1 is 6.5 with network access, low complexity, low privileges, no user interaction, and high confidentiality impact.
Likely exposure
Exposure is limited to Phishing Club deployments running versions earlier than 1.30.2 where an attacker has valid authenticated access. Internet-facing administrative or user-accessible instances carry higher practical risk.
Exploitation context
No active exploitation is indicated in the provided sources, and the CVE is not listed as KEV. Exploitation requires authentication and targets SQL expression injection through sorting behavior, with the reported impact focused on confidentiality rather than integrity or availability.
Researcher notes
The public description identifies CWE-89 in an authenticated endpoint and a patch that allowlists order-by columns while clearing unknown mappings. Evidence supports confidentiality-focused SQL injection risk, but the provided sources do not establish exploitation in the wild or broader affected products.
Mitigation direction
- Upgrade Phishing Club to version 1.30.2 or later.
- Review vendor advisory and commit for the exact fixed behavior.
- Restrict access to Phishing Club to trusted users and networks.
- Audit accounts with access to recipient listing functionality.
- Monitor application and database logs for unusual authenticated query behavior.
Validation and detection
- Inventory Phishing Club deployments and record running versions.
- Confirm affected systems are below version 1.30.2.
- Verify upgraded systems report version 1.30.2 or later.
- Review configuration for externally reachable Phishing Club interfaces.
- Check logs for suspicious sorting or recipient-list requests by authenticated users.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
