Adobe InDesign Update Addresses 2 Vulnerabilities
Tech GuruQuick Answer
The authority published APSB26-145 for Adobe InDesign. Adobe published APSB26-145 with supported updates for InDesign. Adobe states that it is not aware of exploitation of these issues. Affected deployments should be matched to the authority's exact scope and moved to the supported fixed release.
Confirm Scope And Apply The Supported Fix
What to do now: Inventory Adobe InDesign, match the exact affected release or feature, apply the authority-supported fixed build or service remediation, validate the dependent workflow, and preserve evidence.

| CVSS severity | Important |
| Exploitation status | Adobe states that it is not aware of exploitation; no exploitation claim is inferred. |
What Changed
Adobe published APSB26-145 with supported updates for InDesign. Adobe states that it is not aware of exploitation of these issues.
What To Validate Now
- Inventory. Locate Adobe InDesign deployments, versions, enabled features, exposure paths, owners, and dependent services.
- Establish applicability. Compare each deployment with the authority's affected-version statement: InDesign 21.5 and earlier, and 20.5.4 and earlier, on Windows and macOS Do not infer applicability from product family or severity alone.
- Remediate. Apply InDesign 21.6 or 20.5.5 through the supported vendor or project channel, following the current advisory and change-control requirements.
- Validate. Confirm the resulting version or managed-service state, exercise representative functionality and recovery paths, monitor for regressions, and document exceptions.
- 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
Use the exact supported release stream and repository. Test dependencies, clusters, integrations, and rollback before broad deployment; a CVSS rating or reachable feature is not evidence of exploitation.
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.
