What is Countly?

Countly ripped out its custom-code sandbox and rebuilt its Docker stack from scratch in a single LTS drop.

Countly is in an extended security hardening cycle, maintaining two parallel LTS lines — 25.03.x and 24.05.x — with coordinated patch releases. The 25.03.52-LTS was structurally significant: Docker images rebuilt as multi-stage on Debian 13 and Node.js 24 to strip compilers and build tooling from production images, the legacy v8-sandbox replaced by isolated-vm eliminating network, filesystem, and process access from custom hooks, and the A/B testing backend migrated from end-of-life Python 3.8 and pystan to Python 3.12 and cmdstanpy. The 25.03.53 and 24.05.53 patches that followed addressed XSS, OIDC session handling, and embedded widget cross-origin policies.

What is OpenReplay?

OpenReplay moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.

On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.

Countly ripped out its custom-code sandbox and rebuilt its Docker stack from scratch in a single LTS drop.

◆ Current state

Countly is in an extended security hardening cycle, maintaining two parallel LTS lines — 25.03.x and 24.05.x — with coordinated patch releases. The 25.03.52-LTS was structurally significant: Docker images rebuilt as multi-stage on Debian 13 and Node.js 24 to strip compilers and build tooling from production images, the legacy v8-sandbox replaced by isolated-vm eliminating network, filesystem, and process access from custom hooks, and the A/B testing backend migrated from end-of-life Python 3.8 and pystan to Python 3.12 and cmdstanpy. The 25.03.53 and 24.05.53 patches that followed addressed XSS, OIDC session handling, and embedded widget cross-origin policies.

◆ Where it's heading

Countly is hardening its self-hosted security posture — the isolated-vm switch and Docker rebuild reduce attack surface without changing the product surface for end users. Running two LTS tracks simultaneously signals a maturing enterprise customer base that cannot upgrade on a quarterly cadence. Feature development in journey_engine and content continues on a separate lane from the security work, suggesting the two concerns are intentionally decoupled.

◆ Prediction

The Node.js 22/24 migration will propagate to additional components. The isolated-vm change will likely prompt tighter documentation of what custom code can and cannot access. Dual LTS maintenance continues as long as significant deployments remain on 24.05.x.

OpenReplay
ANALYTICS
5.0

OpenReplay moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.

◆ Current state

On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.

◆ Where it's heading

The release feed is all maintenance: dependency and runtime upgrades backported to several self-hosted lines at once, published as timestamped backup tags without feature notes. The quick follow-up fix shows the pgx migration is touching real query paths.

◆ Prediction

Expect more backup tags as the pgx v5 change reaches 1.22 and any further query fixes land; nothing in the entries points to a feature release.
