Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.19% for the current model date.

Compensating controls

  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Unknown Photo Engine (Media Organizer & Lightroom) and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

01

What, why and how

The Photo Engine (Media Organizer & Lightroom) WordPress plugin before 6.5.8 does not verify that a user is authorised to act on the targeted media attachment, allowing authenticated users with the author role and above to delete arbitrary media attachments, including those uploaded by other users and administrators.

What

The Photo Engine (Media Organizer & Lightroom) WordPress plugin before 6.5.8 does not verify that a user is authorised to act on the targeted media attachment, allowing authenticated users with the author role and above to delete arbitrary media attachments, including those uploaded by other users and administrators.

Why

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

How

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

What

The Photo Engine (Media Organizer & Lightroom) WordPress plugin before 6.5.8 does not verify that a user is authorised to act on the targeted media attachment, allowing authenticated users with the author role and above to delete arbitrary media attachments, including those uploaded by other users and administrators.

Why

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

How

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Authorization Bypass Through User-Controlled Key → cause the confidentiality, integrity or availability impact described by the vendor

CWE-639 ↗

CWE-639: Authorization Bypass Through User-Controlled Key. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
