New features#
There are no new features included within this release of the Guardian web application.
Other enhancements#
The following additional enhancements are included within this release of the Guardian web application.
Scan performance improvements#
Several improvements have been made to reduce database load when scans are created. Redundant per-node lookups during scan and file-integrity-monitoring task creation have been eliminated, lowering the work required to start a scan on large estates.
Security updates#
As part of our ongoing commitment to security, vulnerabilities across the Guardian web application have been remediated. This release hardens the handling of report scope parameters, strengthens the isolation of generated report files during export, and updates a third-party dependency flagged by a published security advisory.
Fixed issues#
The following issues have been fixed within this release of the Guardian web application.
- Affects Versions: V3 (onwards)
- Fix Version: V3.68.2
- Problem
- A policy report configured to show only the latest results did not apply the selected date range, so it reported across all time rather than the requested window. In addition, certain scope selections could return an error — for example selecting a node group that resolved to no nodes, or supplying environment or node values in an array form.
- Solution
- The latest-results policy report now applies the selected date range, and the affected scope selections no longer produce an error.
- Affects Versions: V3 (onwards)
- Fix Version: V3.68.2
- Problem
- A connected node that had recently completed a scan could be shown as Offline, while some nodes appeared Online even when their agent was no longer reporting. Node status was derived from a stale stored value rather than the node's actual connectivity, and different pages could disagree on a node's status.
- Solution
- Node status is now derived from real connectivity — a recent agent session for agent nodes, or the most recent reachable scan for agentless nodes — so Online and Offline are reported consistently across the node, environment, and group pages. A node whose agent stops reporting is shown as Offline within a few minutes.
Linux Agent v5.53.1#
Here's what's included in V5.53.1 of the Linux Agent as part of the September 2026 quarterly release.
New features#
There are no new features included within this release of the Linux Agent.
Other enhancements#
The following additional enhancements are included within this release of the Linux Agent.
Security updates#
The Go toolchain and agent dependencies have been updated to remediate vulnerabilities in the agent.
Fixed issues#
The following issues have been fixed within this release of the Linux Agent.
- Affects Versions: V5 (onwards)
- Fix Version: V5.53.3
- Problem
- A trailing slash on the configured connect URL produced a doubled path segment (for example
.../guardian//api/...). Behind an edge that prefix-matches/guardian/api, the doubled-slash path missed the route and fell through, so agent and Connection Manager registration failed with an HTTP 405 error. - Solution
-
The connect URL is now normalised once at startup, so a trailing slash no longer breaks registration regardless of how the URL is entered.
Note
This fixed issue was implemented as part of a hotfix deployed on 29th September 2026.
