An update that solves 11 vulnerabilities, contains two features and has one
security fix can now be installed.
## Description:
This update for golang-github-prometheus-prometheus fixes the following issues:
golang-github-prometheus-prometheus was updated to version 3.13.2:
* Security issues:
* CVE-2026-39821: Fixed validation bypass and privilege escalation in Punycode
label handling (bsc#1266608)
* CVE-2026-56852: Fixed infinite loop on truncated or invalid UTF-8 input in
unicode/norm handling (bsc#1272102)
* CVE-2026-44990: Fixed stored XSS in the new React UI by sanitizing
disallowed xmp elements (bsc#1275205)
* CVE-2026-53606: Fixed incomplete URI scheme validation in sanitize-html that
could enable XSS (bsc#1269966)
* CVE-2026-2303: Fixed heap out-of-bounds read in GSSAPI error handling in
mongo-driver (bsc#1269856)
* CVE-2025-4673: Fixed credential leaks by stopping HTTP client header
forwarding on redirects (bsc#1275206)
* CVE-2023-45289: Fixed credential leaks by stopping header and cookie
forwarding on HTTP redirects (bsc#1275207)
* CVE-2025-61686: Fixed unauthorized file access and path traversal in react-
router storage (bsc#1270711)
* CVE-2026-40181: Fixed open redirect risks to external domains via relative
paths in react-router (bsc#1267528)
* CVE-2026-42342: Fixed DoS risks via unbounded path expansion in the manifest
endpoint (bsc#1267538)
* CVE-2026-42211: Fixed remote code execution risks from prototype pollution
in react-router (bsc#1267534)
* CVE-2026-39882: Fixed memory exhaustion via uncapped HTTP response reading
in OpenTelemetry (bsc#1274221)
* Fixed potential denial-of-service vulnerabilities by updating the gRPC
dependency
* Fixed memory exhaustion and DoS by rejecting snappy-compressed requests
exceeding 32MB limit
* Bug fixes and changes:
* Fixed scrape manager failing to reload properly when SD configuration
changes rapidly.
* Prevent memory leak in remote-write path when the receiving endpoint is
unavailable.
* Native Histograms are no longer experimental. They are fully supported for
production workloads.
* Added support for OpenTelemetry traces within the Prometheus UI to correlate
metrics and traces.
* TSDB compaction speed optimized by improving the block merging algorithm.
* Allow scraping of multiple targets using a single HTTP/2 connection to
reduce overhead.
* Added new metrics to monitor the health of the rule evaluation engine.
* Incompatible: This affects scraping, remote read and write, alerting, and
SD. Network paths might need adjustments to avoid redirects.
* Incompatible: Rule group pagination tokens now use SHA-256 instead of MD5.
Custom API consumers must adapt to the new longer token format.
* Added 'group_limit' parameter to PromQL aggregations to restrict the number
of results.
* Incompatible: promtool relative paths in config files now resolve relative
to the config directory itself, instead of the current working directory.
* Support exporting TSDB blocks directly to cloud storage via the admin API.
* Incompatible: Deprecated remote-write metrics like
prometheus_remote_storage_samples_total are removed in favor of
prometheus_wal_watcher_records_read_total.
* Significant query performance boost for high-cardinality regex matchers.
* Introduce a new UI interface for safely deleting specific time series data
directly.
* Added dynamic relabeling actions to extract substrings using regex capture
groups.
* Fixed UI displaying incorrect time ranges after a timezone change.
* Bumped firewalld-prometheus-config to version 0.2 bumping OpenTelemetry to
1.43.0
