WatchGuard Agent 1.25.14 Fixes Windows Log Directory Permissions
Tech GuruQuick Answer
WatchGuard fixed CVE-2026-115253 in WatchGuard Agent for Windows 1.25.14.0000. Inventory vulnerable endpoints, update through the supported channel, verify directory permissions and log continuity, review suspicious gaps where warranted, and retain evidence.
Confirm Scope And Apply The Supported Remediation
What to do now: Inventory Windows Agent versions and local-user exposure; update affected endpoints to 1.25.14.0000 or later; verify service state, log-directory permissions, and centralized log continuity; investigate unexplained gaps when justified; test management; and retain evidence.

Scope And Authority
| Product scope | WatchGuard Agent for Windows |
|---|---|
| Advisory | CVE-2026-115253 |
| CVE | CVE-2026-115253 |
| Authoritative release date | 2026-10-22 |
| Authority revision date | 2026-10-22 |
| Affected versions | WatchGuard Agent for Windows versions before 1.25.14.0000. The authority requires a local, authenticated non-administrative user for the described path. |
| Fixed version | WatchGuard Agent 1.25.14.0000 or later |
| CVSS base score | 7.3 (CVSS v4.0) |
| CVSS severity | High |
| Exploitation status | WatchGuard does not state that this vulnerability is being maliciously exploited; no exploitation claim is inferred. |
What Changed
WatchGuard corrected permissions on the Agent log directory. A local authenticated non-administrator on a vulnerable Windows endpoint can create, alter, append to, or delete security logs and place other files in a directory owned by a privileged service.
What To Validate Now
- Inventory. Identify Windows endpoints running WatchGuard Agent, exact agent versions, local-user access, endpoint-management policy, log forwarding, owner, and maintenance window.
- Establish applicability. Match each Windows endpoint to the authority's affected range below 1.25.14.0000. Do not infer exposure from WatchGuard product-family presence or CVSS severity alone.
- Remediate. Update WatchGuard Agent for Windows to 1.25.14.0000 or later through the supported WatchGuard management channel.
- Validate. Confirm the running agent version and service state, verify log-directory access controls and centralized log continuity, review unexplained local log gaps or file creation where warranted, test endpoint management, and retain evidence.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
The authority describes a local, authenticated path rather than unauthenticated remote exploitation. Updating the agent does not reconstruct altered or deleted logs; preserve centralized evidence before remediation when tampering is suspected.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
