CVE-2026-87836
LowCVSS 2.7Exploitation Probability (EPSS)
Low risk9th percentile - higher than 9% of all known CVEs
Summary
The Comments Import & Export WordPress plugin before 2.5.4 does not restrict its comment export to users able to moderate comments, nor scope the export to content owned by the requesting user. This allows users with the Author role and above to retrieve every comment on the site, including commenter email addresses, IP addresses, unapproved comment content and comment meta.
Risk Assessment
Low-privilege users can access sensitive personal data of commenters, violating privacy and potentially leading to data protection breaches. This may also expose unapproved content.
Recommendation
Update the Comments Import & Export plugin to version 2.5.4 or later. Restrict comment export to authorized moderators and scope it to user-owned content.
