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 Prometheus?

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default

3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

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.

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default

◆ Current state

3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

◆ Where it's heading

The project is spending its feature budget on start timestamps, appearing across PromQL, TSDB encoding, and remote write V2 in the same release but held behind use-start-timestamps and histograms-st-encoding. Everything else follows the established rhythm of promoting one experimental function per cycle and adding a cloud discovery source. The API deprecations are being staged carefully, warning now and rejecting at the next major.

◆ Prediction

Start timestamps are the obvious candidate to lose their feature flags once the encoding and remote-write halves have run together, and the stats parameter values now warned on will be rejected in the next major.
