Short explanation
Firelight Lightbox WordPress plugin versions prior to 2.3.24 process the image ‘src’ attribute without proper escaping, allowing contributors and higher‑privileged users to inject stored XSS.
Stored XSS enables execution of malicious code in a victim’s browser, leading to session hijacking or page manipulation.
What should be done?
- Apply the vendor’s patch when released
- Properly escape and validate image attributes
- Restrict contributor privileges
- Monitor for suspicious uploads
- Deploy security plugins to mitigate XSS
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.

Show the technical text from the sources
