A critical SQL injection vulnerability (CVE-2025-30590) has been discovered in the Dourou Flickr set slideshows plugin, affecting versions up to 0.9. With a CVSS score of 8.5 (High), this vulnerability could allow attackers to execute arbitrary SQL commands on affected systems.
Technical Analysis
The vulnerability stems from improper neutralization of special elements used in SQL commands within the Dourou Flickr set slideshows plugin. While specific technical details about the vulnerable endpoint aren’t publicly available yet, the classification as SQL injection suggests insufficient input validation or improper parameterization of database queries.
SQL injection vulnerabilities typically occur when:
- User-supplied input isn’t properly sanitized
- Prepared statements aren’t used for database queries
- Input validation is insufficient or improperly implemented
This vulnerability shares characteristics with other recent SQL injection flaws, such as CVE-2025-1094 in PostgreSQL’s psql tool, where improper handling of escaped input led to injection possibilities.
Impact Assessment
Successful exploitation could allow attackers to:
- Execute arbitrary SQL commands on the underlying database
- Read, modify, or delete sensitive data
- Potentially escalate privileges depending on database configuration
- Perform unauthorized actions within the application
The high CVSS score reflects the potential for significant impact, particularly if the vulnerable component handles sensitive user data or authentication functions.
While no public exploit code is currently available for CVE-2025-30590 we highly advise seeking to upgrade to the latest release.
Detection and Mitigation
Until an official patch is released, administrators should:
- Identify affected systems:
- Inventory all installations of Flickr set slideshows plugin (versions ≤ 0.9)
- Implement temporary mitigations:
- Apply WAF rules to block SQL injection patterns
- Restrict database permissions for the application account
- Monitor for unusual database activity
- Prepare for patching:
- Monitor the vendor’s security advisories for updates
- Test patches in a non-production environment before deployment
Conclusion
CVE-2025-30590 represents a significant security risk for organizations using vulnerable versions of the Flickr set slideshows plugin. While details about active exploitation aren’t yet available, the high CVSS score warrants immediate attention.
Security teams should prioritize identifying affected systems and implementing compensating controls until an official patch becomes available. This vulnerability serves as another reminder of the persistent threat posed by SQL injection flaws, despite being a well-understood attack vector for decades.
