CVE-2026-108724 Sylius CVE debrief

Who should care

Defenders responsible for Sylius installations, especially those using versions up to 2.3.0, should be aware of this vulnerability and take steps to verify and mitigate it. This includes operators, platform administrators, vulnerability management teams, and security teams who need to assess exposure, apply patches or mitigations, and monitor for unauthorized access to product reviews.

Why it matters

CVE-2026-108724 is an authorization bypass vulnerability in Sylius that allows unauthenticated attackers to read unmoderated and rejected product reviews. Defenders should prioritize verifying the presence of this vulnerability in their Sylius installations and apply patches or mitigations as available.

• Verify and restrict access to the /api/v2/shop/product-reviews/{id} endpoint
• Monitor for unauthorized access to product reviews
• Apply patches or mitigations as available
• Assess exposure of sensitive information in product reviews

Technical summary

The vulnerability exists in Sylius versions up to 2.3.0 and is caused by the lack of application of the AcceptedExtension filter to the item operation. This allows attackers to enumerate sequential IDs on the GET /api/v2/shop/product-reviews/{id} endpoint to retrieve review titles, ratings, comments, timestamps, and author first names, bypassing merchant moderation. Affected product deployments should be identified in managed environments, and owners should be assigned for follow-up. Official advisories or CVE records should be reviewed to validate affected scope, severity, and vendor guidance.

Defensive priority

Defenders should prioritize verifying the presence of this vulnerability in their Sylius installations, especially if they are using versions up to 2.3.0, and apply patches or mitigations as available.

Recommended defensive actions

• Verify the presence of Sylius versions up to 2.3.0 in your environment
• Apply patches or mitigations as available
• Monitor for unauthorized access to product reviews
• Restrict access to the /api/v2/shop/product-reviews/{id} endpoint
• 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
