What is Cobbler?

Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.

Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.

What is Oh Dear?

Oh Dear's weekly changelogs have carried a security section five weeks running.

Oh Dear, an uptime and site monitoring service, publishes a changelog each week. Since late September, along with features such as custom webhook headers, 30 to 90 days of status page history and AI fix prompts in Broken Links alerts, it has fixed a high-severity SSRF in uptime checks and AI page fetches, a status page CNAME takeover, a reflected XSS and a status page ID leak, restricted scoped API tokens from team-wide endpoints, and made the MCP consent screen show redirect destinations. The MCP URL now opens a landing page in a browser.

Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.

◆ Current state

Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.

◆ Where it's heading

The branch is still gaining features aimed at enterprise data centres rather than winding down: new installer ecosystems in August, directory-backed single sign-on now. Authentication has been a recurring concern since the CVE-2024-47533 admin-API bypass. Releases continue to arrive as rollups from main.

◆ Prediction

Expect further 3.3.x rollups; whether the main line cuts a 3.4 is not visible from these entries.

Oh Dear's weekly changelogs have carried a security section five weeks running.

◆ Current state

Oh Dear, an uptime and site monitoring service, publishes a changelog each week. Since late September, along with features such as custom webhook headers, 30 to 90 days of status page history and AI fix prompts in Broken Links alerts, it has fixed a high-severity SSRF in uptime checks and AI page fetches, a status page CNAME takeover, a reflected XSS and a status page ID leak, restricted scoped API tokens from team-wide endpoints, and made the MCP consent screen show redirect destinations. The MCP URL now opens a landing page in a browser.

◆ Where it's heading

August's large MCP release opened the whole product to AI agents, and the autumn work is closing the gaps that kind of exposure creates: SSRF through AI page fetches, consent redirects and token scope. Several fixes credit outside reporters, which suggests responsible disclosure is active. Product work continues alongside in small, practical items for webhooks, status pages and resellers.

◆ Prediction

Expect security fixes to keep appearing in most weekly changelogs while outside reports continue. AI features are spreading into notifications, as the Broken Links fix prompts show, so more AI-written guidance inside alerts is likely.
