The CVE record's CNA (WPScan) lists File Media Renamer versions up to and including 1.3 as affected. No release containing a fix is confirmed on record.

The File Media Renamer WordPress plugin through 1.3 does not verify that the requesting user is authorised to modify a given media attachment, allowing any user with file-upload privileges to rename attachments belonging to other users, including administrators, and to corrupt unrelated stored site data that referenced the old file path.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
