This means any user granted just a read\u2011only role on a board can modify card details such as titles, content, and timestamps.

The EPSS score is reported as <\u202f1\u202f%, indicating that, at the time of assessment, the likelihood of exploitation is low, and the vulnerability is not listed in the CISA KEV catalog. Attackers would need to combine legitimate authentication with the exposed API endpoints that permit card updates, indicating a remote, \u201cnetwork\u201d level attack vector that is inferred from the API context. Successful exploitation could allow an attacker to alter project data or undermine board integrity, potentially compromising project workflow and reporting."}}}}, "created": "2026-02-09T10:44:20.477195+00:00", "updated": "2026-04-16T17:30:26.000966+00:00", "vendors": ["wekan_project", "wekan_project$PRODUCT$wekan"]}
