CVE-2025-54475 Overview
CVE-2025-54475 is a SQL injection vulnerability [CWE-89] in the JS Jobs plugin for Joomla, affecting versions 1.3.2 through 1.4.4. The flaw allows low-privilege authenticated users to execute arbitrary SQL commands against the underlying database. Successful exploitation can lead to unauthorized data disclosure, modification of records, and full compromise of database confidentiality, integrity, and availability. The vulnerability carries a CVSS 4.0 base score of 8.7. The EPSS score is 0.061% with a percentile of 19.264, indicating low predicted exploitation activity.
Critical Impact
Authenticated low-privilege users can execute arbitrary SQL queries through the JS Jobs plugin, exposing all data stored in the Joomla database.

Technical Details for CVE-2025-54475
Vulnerability Analysis
The JS Jobs plugin extends Joomla with job board functionality, including candidate, employer, and listing management features. The plugin fails to properly sanitize user-supplied input before incorporating it into SQL statements. An authenticated user with low privileges can submit crafted input through plugin parameters and alter query logic. The attack vector is network-based, requires no user interaction, and operates with low attack complexity.
Root Cause
The root cause is improper neutralization of special elements used in an SQL command [CWE-89]. User-controlled values flow into database queries without parameterization or escaping. The plugin concatenates input directly into query strings rather than using prepared statements provided by the Joomla database abstraction layer. This pattern allows attackers to break out of the intended query context and append malicious SQL clauses.
Attack Vector
An attacker first authenticates to the Joomla site using any account with access to JS Jobs functionality. The attacker submits a request containing SQL payloads in vulnerable parameters exposed by the plugin. The malicious input modifies the executed SQL query, allowing extraction of arbitrary table contents through techniques such as UNION-based or boolean-based injection. The attacker can read user credentials, session tokens, and any other data stored in the Joomla database. Depending on database privileges, the attacker can also modify or delete records.
No verified public proof-of-concept code is currently associated with this CVE. Technical detail is available in the GitHub CVE Repository.
Detection Methods for CVE-2025-54475
Indicators of Compromise
- HTTP requests to JS Jobs plugin endpoints containing SQL meta-characters such as ', --, UNION SELECT, or INFORMATION_SCHEMA references.
- Unexpected Joomla database errors logged when low-privilege accounts interact with JS Jobs components.
- Outbound queries from the web application returning unusually large result sets to authenticated users.
- New or modified rows in Joomla user, session, or configuration tables that do not correspond to administrative activity.
Detection Strategies
- Inspect web server access logs for requests to index.php?option=com_jsjobs containing encoded SQL syntax.
- Enable Joomla database query logging and alert on queries containing tautologies such as OR 1=1 or stacked statements.
- Deploy a web application firewall with SQL injection signatures tuned for Joomla component parameters.
- Correlate authentication events with subsequent anomalous query patterns from the same session.
Monitoring Recommendations
- Monitor the JoomSky vendor page for plugin updates and apply patched versions promptly. See JoomSky JS Jobs.
- Track failed and successful logins to low-privilege accounts that subsequently access JS Jobs URLs.
- Baseline normal query volume per user role and alert on deviations exceeding established thresholds.
How to Mitigate CVE-2025-54475
Immediate Actions Required
- Upgrade the JS Jobs plugin to a version later than 1.4.4 once a fixed release is available from JoomSky.
- Restrict access to JS Jobs functionality to trusted authenticated users only.
- Audit Joomla user accounts and revoke privileges that are not required for business operations.
- Review database logs for evidence of prior exploitation across the affected version window.
Patch Information
Consult the JoomSky JS Jobs product page for the latest plugin release and security advisories. Apply the vendor-supplied update on a staging environment before promoting to production. Verify the plugin version after upgrade through the Joomla administrator extension manager.
Workarounds
- Disable the JS Jobs plugin in the Joomla extension manager until a patched version is installed.
- Deploy WAF rules that block SQL injection payloads against com_jsjobs request parameters.
- Apply least-privilege principles to the database account used by Joomla, removing rights such as FILE, DROP, and write access to unrelated schemas.
- Enforce input validation at a reverse proxy layer for requests targeting the JS Jobs component.
# Configuration example: disable the component via Joomla CLI
php cli/joomla.php extension:disable --name="com_jsjobs"
