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.

What is Terragrunt?

Terragrunt 1.2's last candidate finishes eleven experiments and locks down state buckets.

Terragrunt v1.2.0-rc3, dated mid-October, is declared the final candidate: unless a blocker appears, v1.2.0 ships with its contents. The cycle completes eleven experiments, among them OCI, block-iteration, azure-backend and optional-hooks. Two changes need attention: base64gzip() now returns the Go 1.27 encoder's output, which can trigger resource replacements, and S3 bootstrapping no longer adds the RootAccess bucket policy statement.

Oh Dear

5.0

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.

5.0

Terragrunt 1.2's last candidate finishes eleven experiments and locks down state buckets.

◆ Current state

Terragrunt v1.2.0-rc3, dated mid-October, is declared the final candidate: unless a blocker appears, v1.2.0 ships with its contents. The cycle completes eleven experiments, among them OCI, block-iteration, azure-backend and optional-hooks. Two changes need attention: base64gzip() now returns the Go 1.27 encoder's output, which can trigger resource replacements, and S3 bootstrapping no longer adds the RootAccess bucket policy statement.

◆ Where it's heading

The graduation model has repeated at a larger scale: six experiments in v1.1, eleven in v1.2. The candidates ran as stabilization, with fixes concentrated in the CAS, the catalog and the Provider Cache Server. Each breaking change also ships with an escape hatch, base64gzip_compat() or enable_bucket_root_access, which shows how seriously the project treats its 1.0 guarantees.

◆ Prediction

v1.2.0 final is the next release, since rc3 says only regression or urgent fixes will land first. It has not appeared in this feed in the 18 days since rc3.
