What is RSS-Bridge?

The web's duct-tape RSS layer, now quiet for a year after flipping every bridge on by default.

RSS-Bridge generates feeds for sites that removed theirs, and each release is a batch of community fixes to individual bridges plus a handful of new ones. Releases are date-tagged rather than versioned and land every few months, with the most recent in August 2025 — roughly a year of silence since. The core is stable PHP; the churn is in the ~400 site-specific scrapers that break whenever a target site changes markup or adds bot protection.

What is Grype?

Grype has stopped competing on coverage and started competing on how few false positives it prints.

Nearly every release in this window is about match precision rather than new scanning surface. The Go ecosystem gets the most attention — deduplicating the same CVE reported under both a govulndb GO-* ID and its GHSA alias, disabling stdlib CPE matching by default, emitting only stdlib records where appropriate, and respecting withdrawn OSV records. The RHEL side gets parallel work on version streams, RHSA-to-minor-version mapping, and fix dates, with Ubuntu ESM and Chainguard added as data sources.

RSS-Bridge vs Grype: editorial side-by-side

0.0

The web's duct-tape RSS layer, now quiet for a year after flipping every bridge on by default.

◆ Current state

RSS-Bridge generates feeds for sites that removed theirs, and each release is a batch of community fixes to individual bridges plus a handful of new ones. Releases are date-tagged rather than versioned and land every few months, with the most recent in August 2025 — roughly a year of silence since. The core is stable PHP; the churn is in the ~400 site-specific scrapers that break whenever a target site changes markup or adds bot protection.

◆ Where it's heading

The project has been shifting from a curated tool to a general-purpose scraping surface: bridges are now all enabled by default, caching was rewritten, and token-based URL auth was added to make public instances survivable. That combination points at operators running shared instances rather than individuals running one bridge. The maintenance load, however, is entirely community-carried, and the gap since the last release suggests that pipeline has thinned.

◆ Prediction

The next release is likely another routine batch of bridge repairs and additions rather than a core change. The stated intentions in these notes — raising the minimum PHP version and separating the document root from the data folder — remain unshipped, and nothing here indicates when that lands.

Grype has stopped competing on coverage and started competing on how few false positives it prints.

◆ Current state

Nearly every release in this window is about match precision rather than new scanning surface. The Go ecosystem gets the most attention — deduplicating the same CVE reported under both a govulndb GO-* ID and its GHSA alias, disabling stdlib CPE matching by default, emitting only stdlib records where appropriate, and respecting withdrawn OSV records. The RHEL side gets parallel work on version streams, RHSA-to-minor-version mapping, and fix dates, with Ubuntu ESM and Chainguard added as data sources.

◆ Where it's heading

The product is being tuned for teams that already run it in CI and are drowning in output — the unit of progress is a suppressed bad match, not a newly detected one. Reachability analysis is the sharpest expression of that: it moves the question from 'is this version vulnerable' to 'does this code path exist in your binary.' Expect vulnerability data quality and distro-specific correctness to keep consuming most of the release notes.

◆ Prediction

Reachability analysis should widen beyond Go if the false-positive reduction holds, and the pattern of onboarding one new ecosystem or distro data source per minor release looks set to continue.
