mod_auth_openidc vs Scalar: at a glance
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.
What is Scalar?
Scalar's mock server learns event-driven APIs while the reference UI picks up localization
Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.

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.
Scalar

Scalar's mock server learns event-driven APIs while the reference UI picks up localization
◆ Current state
Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.
◆ Where it's heading
AsyncAPI is the clear investment across all three packages — rendered in the reference, filterable in navigation, and now mockable as live event streams. The client and reference lines otherwise trend toward extension points and polish rather than new surface.
◆ Prediction
Expect AsyncAPI support to complete the loop by reaching the API client, so event-driven APIs can be exercised interactively the way REST endpoints already are.
