Photo Engine WordPress plugin: Stored XSS via keyword names
Summary
The Photo Engine WordPress plugin before 6.6.2 does not sanitise or escape keyword names before storing and displaying them on its debugging page. An attacker with an Author account or higher can store malicious script that runs in the browser of an administrator who has enabled this debugging page. Exploitation requires an authenticated account and an administrator action, and the CVSS score is 6.4 (medium).
Affected
- Photo Engine (Media Organizer & Lightroom) WordPress plugin, versions before 6.6.2 (CNA range: 0 to before 6.6.2)
- Note: VulDB states up to 6.6.1, which is consistent with this range
- Note: Vendor is listed as Unknown in the CVE record; Meow Apps is assumed as vendor
Fixed in
- Version 6.6.2 (according to the CNA record; vendor confirmation pending)
Workaround
- Disable the debugging page if it is not needed
- Review and restrict accounts with Author or higher permissions
- Apply only if 6.6.2 cannot be installed; not confirmed by a vendor source
Exploitation
- No evidence of exploitation in the wild found; not listed in KEV
- No public proof-of-concept found
- CISA SSVC: Exploitation none, Automatable no, Technical impact total
Our recommendation
- Update Photo Engine to version 6.6.2 or later once the release is confirmed on WordPress.org or the vendor site
- Check whether the debugging page is enabled and disable it if not needed
- Review accounts with Author or higher and remove unused ones
- Check the fix status of related CVE-2026-120575 (stored XSS, up to 6.5.7) and monitor NVD for the official score
