CVE-2026-25562

Status: AnalyzedMedium (5.3)—

WeKan versions prior to 8.19 contain an information disclosure vulnerability in the attachments publication. Attachment metadata can be returned without properly scoping results to boards and cards accessible to the requesting user, potentially exposing attachment metadata to unauthorized users.

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).
