ApostropheCMS is an open-source Node.js content management system, and sanitize-html provides a simple HTML sanitizer with a clear API. Versions of sanitize-html prior to 2.17.5 use `allowedSchemesAppliedToAttributes` (default: `['href', 'src', 'cite']`) to gate the `naughtyHref()` function that blocks dangerous URI schemes like `javascript:` and `vbscript:`. The HTML specification defines 10+ attributes that accept URIs (`action`, `formaction`, `data`, `poster`, `background`, `ping`, `xlink:href`, `dynsrc`, `lowsrc`), but none of these are included in the default gate list. When a developer allows any of these attributes in their configuration, `javascript:` URIs pass through completely unmodified, enabling XSS. Version 2.17.5 patches the issue.

    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
