Sunlight v0.8.1 [security fix]

This release fixes ANT-2026-88EWBS43, a security vulnerability.

Submissions were deduplicated by looking them up in a SQLite database using a 128-bit key. If a match is found in the deduplication cache, Sunlight signs an SCT over the stored (old) timestamp and index, and the submitted (pre-)certificate.

With 128-bit keys, an attacker could compute a collision offline in 2⁶⁴ work (costing in the order of tens of thousands of dollars), submit a honest certificate, and then obtain an SCT for the colliding certificate, without the latter making it into the log.

In the WebPKI, this would require a colluding, compromised, or separately vulnerable CA, because the TLS BRs require unpredictable entropy in the serial number, making it impossible to compute the collision offline.

Starting in Sunlight v0.8.1 (this release), entries are added to the cache using a 256-bit key.

Existing 128-bit keys are still queried, to avoid a wave of cache misses when upgrading from v0.8.0 (or earlier) to v0.8.1 (or later). This is relatively safe because a collision attack requires control over both entries. Either the attack was executed in the past, in which case the attacker already obtained a forged SCT, or the existing 128-bit keys are honest. With approximately 2³² entries in the cache, a multi-target second preimage attack would require 2⁹⁶ work (taking in the order of a couple years with the same energy consumption as the whole Bitcoin network).

For extra safety, operators can optionally run the new recompute-cache command to rebuild the cache from the backend storage. Once recompute-cache has completed, run

sqlite3 cache.db "ALTER TABLE cache RENAME TO cache_legacy;"

to disable the fallback. This is safe to run concurrently with the log. (Do not use DROP as that would be a long write transaction, blocking the sequencer.)

This vulnerability was discovered by Claude, Anthropic's AI assistant, and triaged by the Anthropic security team in collaboration with Anthropic Research.

v1.24.1 / 2026-07-23

Small bugfix release for promhttp.

What's Changed

Full Changelog: prometheus/client_golang@v1.24.0...v1.24.1

v1.24.0 - 2026-07-20

Changes

• [CHANGE] Minimum required Go version is now 1.25, only the two latest Go versions (1.25 and 1.26) are supported from now on. #1862
• [CHANGE] prometheus: Name validation now always uses the UTF-8 scheme instead of the deprecated model.NameValidationScheme global. Default behavior is unchanged; code that set NameValidationScheme = LegacyValidation no longer gets legacy enforcement at metric, label, and push-grouping construction. #2051
• [CHANGE] api/prometheus/v1: Support matchers (matches[] parameter) in Rules method (Rules(ctx context.Context, matches []string) (RulesResult, error)). #1843
• [CHANGE] api/prometheus/v1: Refactor LabelNames method to return model.LabelNames instead of []string for consistency across the API. #1850
• [CHANGE] exp/api/remote: Simplify Store interface, rename Handler to WriteHandler, and encapsulate write response handling. #1855
• [FEATURE] prometheus: Add new Go 1.26 runtime metrics (/sched/goroutines-created:goroutines, /sched/goroutines/not-in-go:goroutines, /sched/goroutines/runnable:goroutines, /sched/goroutines/running:goroutines, /sched/goroutines/waiting:goroutines, /sched/threads/total:threads). #1942
• [FEATURE] prometheus: Add WithUnit(unit string) option and explicit OpenMetrics unit support in CounterOpts, GaugeOpts, SummaryOpts, and HistogramOpts. #1392
• [FEATURE] prometheus: Expose descriptor construction error through public Err() method on Desc. #1902
• [FEATURE] promhttp: Add opt-in HandlerOpts.CoalesceGather to deduplicate concurrent Gather calls so overlapping scrapes share one collection cycle, preventing goroutine pile-up when the scrape rate outpaces collection time. #1969
• [FEATURE] promhttp: HTTP handlers created by promhttp package now support metrics filtering by providing one or more name[] query parameters. The default behavior when none are provided remains the same, returning all metrics. #1925
• [FEATURE] api/prometheus/v1: Add query formatting endpoint support (/format_query) and FormatQuery(ctx context.Context, query string) (string, error) method. #1846, #1856
• [FEATURE] api/prometheus/v1: Add support for /status/tsdb/blocks endpoint via TSDBBlocks(ctx context.Context) ([]TSDBBlock, error) method. #1896
• [FEATURE] exp/api/remote: Export BackoffConfig to allow customization when using WithAPIBackoff. #1895
• [FEATURE] exp/api/remote: Add RetryCallBack to allow custom logging or handling on retry attempts in the remote write client. #1888, #1890
• [ENHANCEMENT] prometheus/collectors/version: Allow specifying custom labels when registering the version collector. #1860
• [ENHANCEMENT] api: Use cloned http.DefaultTransport when constructing default HTTP clients to prevent accidental mutations of shared global transport state. #1885
• [BUGFIX] prometheus: Recover from collector panics during Gather() and return an error instead of crashing the process. #1961
• [BUGFIX] prometheus: Fix cpu-seconds unit suffix handling for metric go_cpu_classes_gc_mark_assist_cpu_seconds. #1991
• [BUGFIX] promhttp: InstrumentHandlerDuration and InstrumentHandlerCounter no longer panic when given an observer/counter that does not implement ExemplarObserver/ExemplarAdder (e.g. a SummaryVec). The exemplar is dropped and the value is recorded via the plain Observe/Add path, matching the safe-cast already used by Timer.ObserveDurationWithExemplar. #2005
• [BUGFIX] api/prometheus/v1: Fall back to GET requests when POST requests return 403 Forbidden or method not allowed. #2030
• [BUGFIX] api: Respect context cancellation inside httpClient.Do. #1971
• [BUGFIX] exp/api/remote: Fix compression buffer pooling where compressed buffers were released prematurely, causing corrupted remote-write payloads. #1889
• [BUGFIX] exp/api/remote: Reject malformed snappy payloads declaring huge decoded sizes. Enforce a 32MB decoded-size limit to prevent OOM from oversized remote-write requests. #1917
• [BUGFIX] exp/api/remote: Ensure remote write v2 headers cannot be returned on v1 requests. #1927

• build(deps): bump github.com/prometheus/procfs from 0.16.1 to 0.17.0 by @​dependabot[bot] in prometheus/client_golang#1839
