What is Froxlor?

Seven consecutive security releases as froxlor works through an input-validation audit.

Every froxlor release since February has been titled a security release, and the pattern inside them is consistent: batches of validation fixes across the API and frontend rather than responses to single disclosures. The work covers DNS record content validation across LOC, RP, SSHFP, TLSA, NAPTR and TXT types, path traversal and symlink resolution in data export and authorized_keys handling, ownership checks in email and domain operations, CSRF tokens on AJAX actions, and requiring the current password before generating an API key. The June sequence — 2.3.8, then 2.3.9 and 2.3.10 the same day — shows a regression being chased immediately after a fix.

What is OpenTripPlanner?

OpenTripPlanner finished a multi-year migration by deleting its REST API.

OTP releases roughly twice a year and keeps its notes to a handful of notable items, deferring the rest to external changelogs. The recent line has been about API consolidation: 2.6.0 disabled the legacy REST API by default and made the new debug client the default, 2.8.0 removed the REST API outright, and 2.9.0's only listed change is a move to Java 25. Feature work in between went into SIRI extra calls, GTFS-RT platform and headsign changes, and transit filters on the GraphQL planConnection query.

Seven consecutive security releases as froxlor works through an input-validation audit.

◆ Current state

Every froxlor release since February has been titled a security release, and the pattern inside them is consistent: batches of validation fixes across the API and frontend rather than responses to single disclosures. The work covers DNS record content validation across LOC, RP, SSHFP, TLSA, NAPTR and TXT types, path traversal and symlink resolution in data export and authorized_keys handling, ownership checks in email and domain operations, CSRF tokens on AJAX actions, and requiring the current password before generating an API key. The June sequence — 2.3.8, then 2.3.9 and 2.3.10 the same day — shows a regression being chased immediately after a fix.

◆ Where it's heading

This reads as a systematic audit being worked through in order rather than incident response. The fixes group by class — first DNS record content, then path and symlink containment, then ownership and authorisation checks, then CSRF and response filtering — which is what a methodical pass over a hosting control panel's attack surface looks like. A control panel is an unusually high-value target since it holds root-adjacent capability over customer domains, mail and databases, so the concentration on ownership validation and path containment is well aimed. Feature work is essentially absent; the non-security content is translations and dependency bumps.

◆ Prediction

Expect the security-release cadence to continue until the audit is exhausted, with the remaining validation surface — likely the config-service and task-generation paths — as the next area. The same-day 2.3.9 and 2.3.10 sequence suggests the team will keep shipping fast follow-ups rather than batching regressions into the next monthly release.

O0.0

OpenTripPlanner finished a multi-year migration by deleting its REST API.

◆ Current state

OTP releases roughly twice a year and keeps its notes to a handful of notable items, deferring the rest to external changelogs. The recent line has been about API consolidation: 2.6.0 disabled the legacy REST API by default and made the new debug client the default, 2.8.0 removed the REST API outright, and 2.9.0's only listed change is a move to Java 25. Feature work in between went into SIRI extra calls, GTFS-RT platform and headsign changes, and transit filters on the GraphQL planConnection query.

◆ Where it's heading

The GraphQL API is now the only API, and the deprecation of plan in favour of planConnection back in 2.7.0 shows the same consolidation happening inside it. Alongside that, the real-time surface keeps growing — SIRI Lite, extra calls, GTFS-RT support for new and replacement trips — while graph build memory consumption gets cut release over release. The 2.9.0 release being a Java version bump and nothing else suggests the API work has run its course.

◆ Prediction

With the REST removal done and the runtime moved to Java 25, the next release is more likely to concentrate on real-time data handling than on API surface.
