What is CVE-2026-25562?

WeKan versions earlier than 8.19 have a vulnerability that allows unauthorized exposure of attachment metadata. This occurs during the publication of attachment data, where the system does not properly scope results to the specific boards and cards accessible by the user. As a result, sensitive information may become available to users who should not have access to it. To mitigate this issue, it's crucial for users to upgrade to version 8.19 or later.

Human OS v1.0:
Ageing Is an Unpatched Zero-Day Vulnerability.

Remediate biological technical debt. Prime Ageing uses 95% high-purity SIRT6 activation to maintain genomic integrity and bolster systemic resilience.
