CVE-2026-29788

Status: AnalyzedHigh (8.4)—

TSPortal is the WikiTide Foundation’s in-house platform used by the Trust and Safety team to manage reports, investigations, appeals, and transparency work. Prior to version 30, conversion of empty strings to null allows disguising DPA reports as genuine self-deletion reports. This issue has been patched in version 30.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

UI:P requiere interacción del usuario para enviar reporte; manipulación de datos (convertir cadenas vacías a null) falsifica reportes de cumplimiento normativo (DPA). Afecta integridad (VI:L) y disponibilidad (VA:H/SA:H) de reports.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
