Kanboard vs ZenTao: at a glance
What is Kanboard?
Kanboard shipped three security releases in ten days, plus a PHP 8.5 move.
Kanboard is a self-hosted PHP kanban board whose releases are now almost entirely security work, and October tripled the pace. 1.2.55 blocked spoofed proxy IPs from bypassing CAPTCHA and login lockouts and enforced project authorization across several board actions; 1.2.56 moved the Docker image to PHP 8.5 to pick up two PHP CVE fixes; 1.2.57 disables PHP session upload progress against another CVE and stops API lookups from revealing that inaccessible projects exist. WebP attachments and exact-email user search are the only feature additions.
What is ZenTao?
ZenTao posts a 22.0 beta with no notes in the feed.
The only tracked ZenTao entry is the 22.0 beta tag from October 21. It links to a changelog file in the repository and contains no description of what changed.
Kanboard vs ZenTao: editorial side-by-side
Kanboard
5.0PM
Kanboard shipped three security releases in ten days, plus a PHP 8.5 move.
◆ Current state
Kanboard is a self-hosted PHP kanban board whose releases are now almost entirely security work, and October tripled the pace. 1.2.55 blocked spoofed proxy IPs from bypassing CAPTCHA and login lockouts and enforced project authorization across several board actions; 1.2.56 moved the Docker image to PHP 8.5 to pick up two PHP CVE fixes; 1.2.57 disables PHP session upload progress against another CVE and stops API lookups from revealing that inaccessible projects exist. WebP attachments and exact-email user search are the only feature additions.
◆ Where it's heading
The audit that ran from LDAP escaping through API response shape is now reaching information leaks by error message: returning false instead of a 403 so the API doesn't confirm a project exists. The Docker image has become part of the security perimeter, with two of the three releases changing PHP runtime settings. Features remain small and incidental.
◆ Prediction
Expect further releases tracking upstream PHP and Alpine security fixes, since the Docker image now ships on PHP 8.5 and has needed two runtime changes in ten days.
ZenTao
2.5PM
ZenTao posts a 22.0 beta with no notes in the feed.
◆ Current state
The only tracked ZenTao entry is the 22.0 beta tag from October 21. It links to a changelog file in the repository and contains no description of what changed.
◆ Where it's heading
A beta of a new major version suggests a larger release is in progress, but nothing in the feed says what it contains.
◆ Prediction
Unclear: the entry does not show what 22.0 changes or when a stable version will follow.
