CVE-2025-27753
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA SQLi vulnerability in RSMediaGallery component 1.7.4 - 2.1.6 for Joomla was discovered. The vulnerability is due to the use of unescaped user-supplied parameters in SQL queries within the dashboard component. This allows an authenticated attacker to inject malicious SQL code through unsanitized input fields, which are used directly in SQL queries. Exploiting this flaw can lead to unauthorized database access, data leakage, or modification of records.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify RSMediaGallery component installationLocate the RSMediaGallery component in your Joomla installation (typically in /components/com_rsmediagallery/) and check the manifest file or version.php for the installed version numberAffected if The component is present but the version cannot be determined or is in the range 1.7.4 through 2.1.6
-
Confirm version against affected rangeCompare your installed RSMediaGallery version to the affected range: 1.7.4 <= version <= 2.1.6Affected if The installed version falls between 1.7.4 and 2.1.6 inclusive
-
Verify dashboard functionality is accessibleCheck if the RSMediaGallery administrator dashboard is accessible by navigating to Components > RSMediaGallery in the Joomla administrator panel, or by accessing the dashboard component endpoint directlyAffected if The dashboard functionality is enabled and accessible to authenticated users
-
Confirm user account access existsVerify that user accounts with access to the RSMediaGallery component exist in the Joomla user management system (Users > Manage)Affected if Any valid user credentials exist that can authenticate to the RSMediaGallery component dashboard
Your environment is affected if RSMediaGallery is installed with a version between 1.7.4 and 2.1.6 and the dashboard functionality is accessible to authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace direct string concatenation in SQL queries with parameterized queries/prepared statements; implement proper input validation and escaping; update to patched version if available.
