Photo Engine WordPress plugin: Broken access control allows media deletion
Summary
The Photo Engine (Media Organizer & Lightroom) WordPress plugin before version 6.6.2 does not check whether a user may delete the media in a collection before deleting it together with the collection. Users with the Author role or higher can therefore permanently delete other users' synced media, including media uploaded by administrators. The attack requires a valid Author account, so it is an insider or post-login risk rather than an anonymous internet threat.
Affected
- Photo Engine (Media Organizer & Lightroom) WordPress plugin (WordPress.org slug wplr-sync) from 0 to before 6.6.2 (CNA range)
- Some third-party sources state up to 6.6.1; the CNA range is authoritative.
Fixed in
- Version 6.6.2 (according to the CVE description and CNA record)
- Not yet confirmed on WordPress.org at the time of research; the listing still showed 6.6.1 as current.
Workaround
- No vendor-published workaround known.
- Review and reduce Author-level accounts and remove unused ones.
- Keep current backups of the media library, as the deletion is permanent.
Exploitation
- Exploited in the wild: no evidence on record. Not listed in CISA KEV.
- Public proof of concept: none found at the time of research.
- CISA SSVC: exploitation none, automatable no, technical impact partial.
Our recommendation
- Update the plugin to version 6.6.2 or later as soon as it is confirmed available, and check the WordPress.org changelog.
- Review which users hold the Author role or higher and remove accounts that are not needed.
- Verify that media library backups work and can be restored.
- Monitor for unexpected collection or media deletions.
- Note that the CVSS vector lists high privileges (PR:H), which looks inconsistent with the Author role; do not rely on the 4.9 score until NVD confirms it.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
