Mailerpress Newsletter Email Marketing Ai Automation
Monthly
Unauthenticated campaign content tampering in the MailerPress - Newsletter, Email Marketing & AI Automation WordPress plugin (versions ≤ 1.5.0) allows any remote actor to overwrite active email campaign HTML by invoking the revision-restore REST endpoint without credentials. The campaign revision-restore route (POST /wp-json/mailpress/v1/campaign/<id>/restore-revision/<revision_id>) was registered in the WordPress REST API without a permissionCallback, bypassing the authorization layer entirely. No public exploit code has been identified at time of analysis and this CVE is not listed in the CISA KEV catalog, though the attack is trivially executable against any reachable WordPress instance running the affected plugin.
Unauthorized contact data modification in MailerPress (WordPress plugin, versions up to and including 1.5.0) is achievable by any unauthenticated remote attacker via a missing capability check on the REST API endpoint `mailerpress/v1/contact`. The root cause (CWE-862) means WordPress's permission framework is entirely bypassed for this endpoint, exposing the contact database to arbitrary writes without credentials. No public exploit has been identified at time of analysis and the issue is not listed in CISA KEV, but the low attack complexity and zero authentication requirement make this trivially exploitable by automated scanners.
