Security readout for executives and security teams
Plain-English summary
This CVE describes a cross-site scripting flaw in NextGEN Gallery for WordPress. Malicious content in image alt or title text could affect an administrator who views the image in the admin page. The source bundle says versions 2.2.30 and earlier are affected and version 2.2.45 fixed it.
Executive priority
Prioritize remediation for public WordPress sites using this plugin, especially where multiple users manage gallery content. This is not evidenced as actively exploited, but XSS affecting administrators can create meaningful account and site-control risk.
Technical view
The issue is XSS in the Image Alt & Title Text handling of Imagely NextGEN Gallery. The stated attack path requires a victim viewing the image in an administrator page. The provided sources do not give CVSS, CWE, privileges required, or payload details.
Likely exposure
Exposure is likely limited to WordPress sites running NextGEN Gallery 2.2.30 or earlier. Risk is higher where non-admin or untrusted users can influence gallery image metadata later viewed by administrators.
Exploitation context
The source bundle does not show CISA KEV listing or evidence of active exploitation. The described path is administrator-page viewing of crafted image metadata, but source evidence is incomplete on how attackers can set that metadata.
Researcher notes
The record is sparse: no CVSS, CWE, CPE, exploit status, or detailed vendor advisory content is included. Analysis should stay bounded to NextGEN Gallery 2.2.30 and earlier, admin-page XSS via image alt/title text, fixed in 2.2.45.
Mitigation direction
- Upgrade NextGEN Gallery to version 2.2.45 or later.
- Inventory WordPress sites for NextGEN Gallery versions 2.2.30 and earlier.
- Restrict image metadata editing to trusted administrators until upgraded.
- Check vendor and FortiGuard references for any newer guidance.
Validation and detection
- Confirm installed NextGEN Gallery versions across WordPress assets.
- Verify no production site remains on version 2.2.30 or earlier.
- Review who can create or edit gallery image alt and title text.
- Review recent gallery metadata changes for suspicious entries.
- Confirm administrator-facing gallery pages are updated after remediation.
