CVE-2026-24749 silverstripe CVE debrief

Who should care

Defenders and developers using Silverstripe Framework and Assets Module should assess exposure and prioritize verification and upgrades to fixed versions. They must ensure proper file permissions and access grants to prevent bypassing. Operators of affected platforms and security teams should review and update DataObject classes that use DBFile directly in $db configuration.

Why it matters

The Silverstripe Assets Module vulnerability allows unauthorized access to files, bypassing file permissions. Defenders and developers must assess exposure, verify and upgrade to fixed versions, and ensure proper file permissions and access grants.

• Defenders must verify and upgrade to fixed versions to prevent unauthorized access to files
• Exposure assessment is required to determine if deployments are affected
• Proper file permissions and access grants must be ensured to prevent bypassing
• Verification of DataObject classes using DBFile directly in $db configuration is necessary

Technical summary

The Silverstripe Assets Module vulnerability causes images rendered in templates or accessed via DBFile::getURL() or DBFile::getSourceURL() to incorrectly add an access grant to the current session, bypassing file permissions. This issue affects versions prior to 2.4.5 and 3.0.0-rc1 through 3.1.2, and has been fixed in versions 2.4.5 and 3.1.3. The vulnerability allows unauthorized access to files, which can be mitigated by verifying and upgrading to fixed versions, assessing exposure in deployments, and ensuring proper file permissions and access grants.

Defensive priority

Defenders should prioritize verifying and upgrading to fixed versions, assessing exposure in their deployments, and ensuring proper file permissions and access grants.

Recommended defensive actions

• Verify and upgrade to fixed versions (2.4.5 or 3.1.3) of Silverstripe Assets Module
• Assess exposure in deployments and ensure proper file permissions and access grants
• Review and update DataObject classes that use DBFile directly in $db configuration
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
