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 Productboard?

Productboard's v2 documents API now keeps plain web addresses and emoji as ordinary text.

Productboard's v2 API spent the summer closing v1 parity gaps, then in September made entity types a workspace-specific string. October added field values on relationships, exact-match text search and 308 redirects for merged entities. On November 5 the documents content endpoints changed how they treat bare URLs, email addresses and emoji: they now stay plain text unless written with explicit link syntax.

Kanboard vs Productboard: editorial side-by-side

K5.0

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.

P5.0

Productboard's v2 documents API now keeps plain web addresses and emoji as ordinary text.

◆ Current state

Productboard's v2 API spent the summer closing v1 parity gaps, then in September made entity types a workspace-specific string. October added field values on relationships, exact-match text search and 308 redirects for merged entities. On November 5 the documents content endpoints changed how they treat bare URLs, email addresses and emoji: they now stay plain text unless written with explicit link syntax.

◆ Where it's heading

The v2 API is being tightened release by release so integrations can round-trip data without surprises. The documents format is the latest surface to get exact, documented rules.

◆ Prediction

Expect further dated v2 entries that fill in document and entity edge cases; nothing in the entries points to a larger change soon.
