CVE-2026-49262 aimeos CVE debrief

Who should care

Defenders responsible for Aimeos Pagible installations, particularly those with exposed administrative proxy routes, should assess their exposure and prioritize upgrading to version 0.10.4 or later.

Why it matters

Defenders should prioritize verifying exposure of the administrative proxy route and upgrading to version 0.10.4 or later to prevent potential access to internal network resources and cloud metadata endpoints.

• Access to internal network resources may be compromised
• Cloud metadata endpoints may be accessible to attackers
• Verification of exposure and remediation are required
• Upgrade to version 0.10.4 or later to fix the issue

Technical summary

The Aimeos Pagible content management system prior to version 0.10.4 contains a Server-Side Request Forgery (SSRF) vulnerability via DNS Rebinding in the administrative proxy route (cmsproxy). A Time-of-Check to Time-of-Use (TOCTOU) race condition exists between the URL validation phase and the actual HTTP request phase, allowing attackers to access internal network resources and cloud metadata endpoints.

Defensive priority

Defenders should prioritize verifying exposure of the administrative proxy route and upgrading to version 0.10.4 or later.

Recommended defensive actions

• Verify exposure of the administrative proxy route (cmsproxy) in Aimeos Pagible installations
• Upgrade to version 0.10.4 or later
• Monitor internal network resources and cloud metadata endpoints for unauthorized access
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, but additional information on affected deployments and exploitation attempts is limited. The Aimeos Pagible content management system versions prior to 0.10.4 are vulnerable to this issue. There is no evidence of public exploitation, but defenders should verify exposure and apply the patch. Limited source information is available, and defenders should exercise caution when assessing their exposure.
