CVE-2026-88855 OrdaSoft.com CVE debrief

Who should care

Joomla site administrators, security teams, and users with core.manage permissions should be aware of this vulnerability and take immediate action to patch or mitigate it. The vulnerability allows an attacker with core.manage permissions to gain full read/write access to the database, potentially leading to data breaches and unauthorized access. Affected operators and platform administrators should prioritize patching or applying compensating controls to

Why it matters

This vulnerability allows an attacker with core.manage permissions to gain full read/write access to the database, potentially leading to data breaches and unauthorized access.

• Potential data breaches due to unauthorized database access
• Possible extraction of sensitive data, including password hashes
• Risk of lateral movement within the network
• Need for immediate patching or mitigation

Technical summary

The OrdaSoft Joomla Gallery extension for Joomla is vulnerable to authenticated, privileged SQL injection due to improper sanitization of user-input values in the saveGallery() function. Specifically, the extension fails to properly quote or cast integer values from category_names[], catOrderIds, and image-ordering fields, allowing an attacker to inject SQL. This vulnerability can be exploited by an attacker with core.manage permissions, potentially leading to full read/write access to the database, including extraction of sensitive data such as password hashes.

Defensive priority

High priority for Joomla site administrators and security teams

Recommended defensive actions

• Update the OrdaSoft Joomla Gallery extension to version 6.2.7 or later
• Restrict core.manage permissions to trusted users
• Monitor database activity for suspicious queries
• 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 vulnerability exists in the saveGallery() function of the OrdaSoft Joomla Gallery extension. This function fails to sanitize SQL content when concatenating user-input values into SQL queries, specifically from category_names[], catOrderIds, and image-ordering fields. These values are passed through a hand-rolled parser into Joomla's Input object and then read back with ARRAY/STRING filter types, which do not sanitize SQL content. This oversight allows an attacker with core.manage permissions to inject SQL and gain full read/write
