1) Authorization bypass through user-controlled key (CVE-ID: N/A)

CWE-ID: CWE-639 - Authorization Bypass Through User-Controlled Key

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to disclose sensitive information from arbitrary private board cards and attachment bytes.

The vulnerability exists due to authorization bypass through user-controlled key in the single-card Excel export endpoint when handling requests with an authorized board identifier and an unrelated card identifier. A remote user can send a specially crafted request to disclose sensitive information from arbitrary private board cards and attachment bytes.

The list identifier is not used in the data query, and a known card identifier is required.
