CVE-2026-42211
React Router's vendored turbo-stream v2 allows arbitrary constructor invocation via TYPE_ERROR deserialization leading to Unauth RCE
React Router is a router for React. In versions 7.0.0 through 7.14.1, when using Framework Mode, a combination of steps could potentially allow unauthorized remote code execution (RCE) through external requests. This attack requires the application code to have an existing prototype pollution vulnerability, which can then be leveraged in a 2-step attack where the second step triggers unauthorized RCE on the remote server. This does not impact applications using Declarative Mode (<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>). This is patched in version 7.14.2.

8.1
React Router's vendored turbo-stream v2 allows arbitrary constructor invocation via TYPE_ERROR deserialization leading to Unauth RCE
When using React Router v7 in Framework Mode, there exists a combination of steps that could potentially allow unauthorized RCE through external requests. This first requires the application code to have an existing prototype pollution vulnerability. This can be leveraged into a 2-step attack in which the second step can trigger unauthorized RCE on the remote server.
[!NOTE] This does not impact your React Router application if you are using Declarative Mode (
<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>).

Security update 5.2.1 for Multi-Linux Manager Client Tools
This update 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
