What is Doppler?

Doppler shipped an on-prem build — the secrets manager that only ran as SaaS now runs in your datacenter.

Monthly digests, each one a list, and the captured bodies cut off partway so only the opening items are legible. June leads with Doppler On-prem, alongside role filters on the dashboard, warnings that show downstream impact before deleting inherited or referenced data, and fuzzy matching in secret search. The months before it are steady platform work: Integration Access Scoping via API and Terraform, the ability to redact every historical version of a secret so deleted history is genuinely gone, Azure Service Principal rotated and dynamic secrets, activity-log forwarding to multiple destinations per service type including AWS SQS, and CLI token creation from the MCP server.

What is mod_auth_openidc?

mod_auth_openidc keeps hardening its own attack surface, one audited subsystem at a time

This is the Apache module implementing OpenID Connect relying-party support, and its 2.4.20.x line has been an almost unbroken security programme. An internal audit turned up eight issues including an identity-header bypass; PBKDF2 key stretching changed the session encryption key and invalidated every session created by 2.4.19.x and earlier; out-of-bounds reads and writes were fixed in the state-cookie parser. The latest release continues in the same register, hardening file-backed metadata and cache I/O and the shared-memory cache itself.

Doppler shipped an on-prem build — the secrets manager that only ran as SaaS now runs in your datacenter.

◆ Current state

Monthly digests, each one a list, and the captured bodies cut off partway so only the opening items are legible. June leads with Doppler On-prem, alongside role filters on the dashboard, warnings that show downstream impact before deleting inherited or referenced data, and fuzzy matching in secret search. The months before it are steady platform work: Integration Access Scoping via API and Terraform, the ability to redact every historical version of a secret so deleted history is genuinely gone, Azure Service Principal rotated and dynamic secrets, activity-log forwarding to multiple destinations per service type including AWS SQS, and CLI token creation from the MCP server.

◆ Where it's heading

Two commitments run through this window. The first is that everything must be reachable programmatically — API and Terraform coverage for access scoping, Change Requests endpoints in the v3 API, service account identity management, MCP-driven CLI authentication. The second is control over the secret's whole lifecycle rather than its current value: rotation, dynamic generation, history redaction, and delete-time impact warnings all treat a secret as something with a past and dependents. On-prem is what those two make sellable to the customers who could not use Doppler at all.

◆ Prediction

Expect the on-prem build to drive the next stretch of work — parity gaps, upgrade paths, and air-gapped handling of the integrations that currently assume outbound access. The truncated digests make anything finer than that unreadable from the feed.

mod_auth_openidc keeps hardening its own attack surface, one audited subsystem at a time

◆ Current state

This is the Apache module implementing OpenID Connect relying-party support, and its 2.4.20.x line has been an almost unbroken security programme. An internal audit turned up eight issues including an identity-header bypass; PBKDF2 key stretching changed the session encryption key and invalidated every session created by 2.4.19.x and earlier; out-of-bounds reads and writes were fixed in the state-cookie parser. The latest release continues in the same register, hardening file-backed metadata and cache I/O and the shared-memory cache itself.

◆ Where it's heading

The project is working outward from the code paths an attacker actually reaches: cookie parsing, then session key derivation, then cache storage and the files the module reads at runtime. Keyed hashing of cache keys to stop bucket-chain flooding, refusing non-regular files, capping allocations and writing metadata atomically all address resource-exhaustion and file-substitution classes rather than single bugs. Packaging and commercial distribution notes take up an increasing share of each release body, with Redis and Valkey over TLS behind a commercial agreement.

◆ Prediction

With the cache and file layers now hardened, the remaining large surface is the HTTP client and provider metadata handling, so that is the likeliest next area — and the 2.4.20.x line should settle into ordinary maintenance once the audit backlog is worked through.
